[0031] The principle and spirit of the present disclosure are explained in detail below with reference to several representative embodiments of the present disclosure.

[0032] As described in the background technology, in the related technologies, the coverage of optical fiber communication is not wide enough in extreme environments, the construction cost of wireless private networks is high, and the adaptability of satellite-ground fusion networks to mountain power grid scenarios cannot be confirmed. Specifically:

[0033] In related technologies, a fiber-optic communication network is a high-speed data transmission system that uses optical fiber as a transmission medium. It transmits information by reflecting light signals inside the optical fiber. Fiber-optic communication has the advantages of fast transmission speed, large bandwidth, strong anti-interference ability, low signal attenuation, and long transmission distance. It is very suitable for long-distance and large-capacity data transmission needs. In modern communication networks, fiber-optic communication is one of the core technologies for building high-speed Internet, data centers, cable TV networks, and telephone networks. Since fiber-optic communication is not subject to electromagnetic interference and can provide a high degree of communication security, it is also widely used in military, finance, government and other fields with high security requirements. With the continuous advancement of fiber-optic technology and optoelectronic technology, fiber-optic communication networks have been widely deployed and applied around the world and have become an important part of the information infrastructure of modern society.

[0034] However, the "Shagohuang" region, which is the junction of the desert and the Gobi Desert, has been undergoing an energy revolution in recent years, especially in the field of new energy. With the large-scale deployment of new energy power generation projects, the demand for power supply in these areas has surged, and the requirements for communication networks have also increased accordingly; although fiber-optic communication technology is widely used in power transmission systems due to its high bandwidth, low latency and anti-interference performance, it cannot fully cover all Shagohuang areas; the complex terrain and harsh climate in the Shagohuang area have brought great challenges to the construction and maintenance of communication infrastructure; in addition, due to the remote geographical location, the communication sites in these areas are often distributed far away, which increases the length and complexity of the communication link; therefore, although fiber-optic communication technology can provide efficient communication services, in some specific areas, such as the edge of the desert or mountainous areas, the high cost and difficulty of laying optical fibers make it difficult for optical fiber communication networks to fully cover.

[0035] In related technologies, a wireless private network is a professional network based on a wireless network that is provided for specific industries or professional users. It is distinguished from a public network (i.e., the public network), which is mainly used by public users; the characteristics of a wireless private network are its service scope, security, and adaptability to the needs of specific industries; these networks are usually used in key areas such as the military, government, transportation, and power supply to ensure the security and confidentiality of the business and the stability and reliability of the network. With the development of technology, especially the advent of the 5G era, wireless private networks have become more powerful and customizable, able to support more complex business needs and improve network performance; for example, the application of 5G technology enables wireless private networks to provide large bandwidth, low latency, and high-reliability network connections to meet the security, reliability, and high-performance communication needs of industries such as smart manufacturing, energy, and mining.

[0036] However, due to the unique geographical and climatic conditions of the Shagohuang area, the construction of traditional wireless private networks faces huge challenges; these areas are usually located in remote areas with complex terrain and difficult communication coverage, resulting in high construction costs, which in turn reduces the application prospects of wireless private networks in these areas; in addition, the communication reliability in these areas is low, which not only affects the information exchange efficiency of the power business, but may also cause obstacles to data transmission in emergency situations.

[0037] Among the relevant technologies, satellite communication networks have the characteristics of wide coverage, less environmental restrictions and high reliability. They can effectively solve the problems of limited ground network communication coverage and low reliability in remote desertified areas, provide seamless communication coverage for remote desertified areas, and enhance the communication capabilities of remote desertified areas with high data service demands. Therefore, the high, medium and low orbit multi-layer subnets are integrated with the ground multi-layer cellular network to build a satellite-ground integrated network that can cover all mountain power grids. It can provide ubiquitous and omnipresent communication services for power services in desertified areas.

[0038] However, although satellite network routing technology has made significant progress, existing research has not explored the application of satellite networks in mountain power grids and the optimization of their routing strategies. In particular, considering the special environment and needs of mountain power grids, how to use these advanced technologies to ensure efficient and stable operation of the network, and how to adjust routing algorithms to cope with the unique communication challenges in mountainous areas, is still an unresolved issue.

[0039] In order to solve the above problems, the present disclosure provides a satellite-ground integrated network communication method and related device solutions for power services in the Shagohuang area, specifically including:

[0040] Determine the satellite operation cycle, build a satellite transmission network based on the satellite operation cycle, determine the data transmission link of the satellite transmission network, select the data transmission link, obtain the satellite network transmission path, determine the Shagohuang area power service data packet, and transmit the Shagohuang area power service data packet to the client based on the satellite network transmission path. In this scheme, there are two main data unloading fusion architectures of the satellite-ground fusion network, namely: satellite-ground hybrid relay network architecture and satellite-ground collaborative network architecture; the satellite-ground hybrid relay network architecture is further divided into a basic relay architecture and a collaborative relay architecture; in the basic relay architecture, power grid users cannot communicate directly with satellites, and satellites need to transmit signals to power grid users through ground relays; the transmission process of the basic relay architecture will include two stages; in the basic relay architecture, with the help of ground relays, even if the direct link is blocked, users can communicate with satellites through relays, thereby improving the stability of the system; however, this architecture requires dedicated ground relays, and traditional ground cellular networks are not integrated into the system, which severely limits The application and development of this architecture; in the collaborative relay architecture, users can obtain signals through satellite direct connection and ground relay; with the help of ground relay, the signal quality can be improved by superimposing two signals, thereby improving system performance when the direct link is blocked; the collaborative relay architecture still needs to rely on ground relay, but the high construction cost of ground relay directly limits the application of this architecture, and cannot relieve the pressure of satellite network and improve network service capabilities; the satellite-ground collaborative network architecture is the integration of satellite and ground network, realizing the coordination of satellite and ground network; in the satellite-ground collaborative network, users can access both ground network and satellite network, and flexibly choose to access network according to network coverage. For example, when the power grid is within the coverage of the ground network, it can access the ground cellular network to obtain low-cost network services; but when the power grid is located in the Shagohuang area, the power grid users will access the satellite network to continue to obtain services; based on the collaboration of the two networks, the satellite-ground fusion network architecture can achieve ubiquitous coverage and uninterrupted services.

[0041] At the same time, considering that the mobility of satellite nodes leads to dynamic changes in satellite network topology, the switching of access to satellites will lead to the use of the satellite's secure virtual network function; in this case, in order to reduce the security cost consumption caused by the switching of access to satellites, the secure virtual network function is deployed on the satellite nodes; in addition, due to the wide coverage of satellites, redundantly deployed secure virtual network functions will also be used in turn within their coverage, which solves the problem of dynamic changes in satellite network topology and realizes the overall protection of the satellite-ground fusion network.

[0042] Since the distance between the power business in Shagohuang area and the distant main station is long and the transportation is very inconvenient, the cost of deploying a wired network is too high; the complex terrain also leads to insufficient coverage of the wired network, so the fiber-optic wired network is not suitable for remote information transmission of the power business in Shagohuang area; similarly, the wireless public network has not been able to fully cover the Shagohuang area; since the satellite communication network has advantages in coverage, throughput, network recovery, etc., the present invention combines the characteristics of the power business in Shagohuang area and the advantages of the satellite communication network, and uses satellite communication to transmit the electricity consumption information collected inside the power grid to the remote main station; this ensures the timeliness and reliability of the data return of the transmission line in Shagohuang area; therefore, the satellite network is used as the backbone communication network for data transmission between the power grid and the main station.

[0043] In terms of the transmission performance of the constellation system, since information is transmitted between satellite nodes by storing and forwarding data packets, changes in link length and forwarding hops will affect changes in end-to-end delay. Different communication services and traffic volumes will also lead to different performance of the constellation system. Based on this situation, it is particularly important to build a multi-target constellation routing solution. The Dijkstra algorithm has the advantages of high stability, small amount of calculation, and fast path search, and has a wide range of applications. Since the link status between each satellite node changes frequently, it is feasible to use the Dijkstra algorithm for optimization. However, the time complexity of the Dijkstra algorithm is relatively high, so it is necessary to optimize the Dijkstra algorithm to reduce the time complexity.

[0044] Priority queue is a special queue, usually implemented by binary tree. Priority queue has the characteristics of heap order. If you want to quickly find the minimum element in the queue, the minimum element should be at the root of the binary tree, and any other node must be smaller than its child node, which is a minimum heap. If you want to find the maximum element, the maximum element should be at the root of the binary tree, and any other node must be larger than its child node, which is a maximum heap. Since the routing solution of the present invention is to find the shortest path between two satellite nodes, it is necessary to establish a corresponding minimum heap binary tree. The traditional Dijkstra algorithm compares and sorts the data after finding multiple paths, and then selects the minimum value. However, adding a minimum heap to optimize the priority queue can reduce the sorting and comparison time of the Dijkstra algorithm.

[0045] In the satellite-ground fusion network, data transmission performance is affected by factors such as the connection status between satellite nodes, remaining bandwidth, remaining energy, communication overhead, etc. According to the proposed multi-objective optimization model for the satellite-ground fusion network, the minimum energy threshold and the minimum remaining bandwidth threshold are first determined, and then a set of candidate paths are established, and the Dijkstra algorithm is used to reduce the calculation time.

[0046] After introducing the basic principles of the present disclosure, various non-limiting embodiments of the present disclosure are described in detail below.

[0047] refer to Figure 1 , which is a schematic diagram of an application scenario of the satellite-ground integrated network communication method for the power business in the Shagohuang area provided by the exemplary embodiment of the present disclosure.

[0048] This application scenario includes a terminal device 101 and a server 102. The terminal device 101 and the server 102 may be connected via a wired or wireless communication network to achieve data interaction.

[0049] The terminal device 101 may be an electronic device with data transmission and multimedia input / output functions close to the user side, including but not limited to a desktop computer, a mobile phone, a mobile computer, a tablet computer, a media player, a smart wearable device, a personal digital assistant (PDA) or other electronic devices capable of realizing the above functions. The electronic device may include a processor and a display screen with a touch input function, the display screen is used to present a graphical user interface, the graphical user interface can display an application interface, and the processor is used to process application data, generate a graphical user interface, and control the display of the graphical user interface on the display screen.

[0050] Server 102 can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers. It can also be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), as well as big data and artificial intelligence platforms.

[0051] In some exemplary embodiments, the satellite-ground integrated network communication method for the power business in the Shagohuang area can be run on the terminal device 101 or the server 102.

[0052] When the satellite-ground integrated network communication method for the power business in Shagohuang area runs on server 102, server 102 is used to provide the satellite-ground integrated network communication service for the power business in Shagohuang area to the user of terminal device 101, and the terminal device 101 is installed with a client for communicating with server 102.

[0053] The server 102 determines a satellite operation cycle, and the server 102 constructs a satellite transmission network based on the satellite operation cycle;

[0054] The server 102 determines the data transmission link of the satellite transmission network, and the server 102 selects the data transmission link to obtain the satellite network transmission path;

[0055] The server 102 determines the Shagohuang area electricity service data packet, and the server 102 transmits the Shagohuang area electricity service data packet to the terminal device 101 terminal device 101 client based on the satellite network transmission path.

[0056] It should be noted that the above application scenarios are only shown to facilitate understanding of the spirit and principle of the present disclosure, and the embodiments of the present disclosure are not limited in this respect. On the contrary, the embodiments of the present disclosure can be applied to any applicable scenario.

[0057] refer to Figure 2 , a satellite-ground fusion network communication method for power business in the Shagohuang area is applied to a server, and the method comprises the following steps:

[0058] Step S210: Determine a satellite operation cycle, and construct a satellite transmission network based on the satellite operation cycle.

[0059] In specific implementation, the methods for determining the satellite operation period include but are not limited to at least one of the following:

[0060] Use aerospace dynamics models, such as the Kepler orbit model and the two-body problem model, to determine the satellite's operating period. Calculate the satellite's operating period based on the spacecraft's ephemeris data and the satellite's precise position and velocity information. Determine the satellite's operating period by actually observing the satellite's trajectory and velocity and combining it with the laws of physics. Use a satellite orbital period calculator to calculate the satellite's operating period or analyze the satellite's orbital parameters, such as orbital altitude, inclination, eccentricity, etc., to determine the satellite's operating period.

[0061] In the above exemplary embodiments, a method for determining the satellite operation period is introduced. Next, a method for constructing a satellite transmission network is introduced:

[0062] In this exemplary embodiment, building a satellite transmission network based on the satellite operation cycle includes:

[0063] The satellite operation cycle is divided to obtain dynamic topology information of the satellite network, at least two satellite nodes are obtained based on the dynamic topology information of the satellite network, at least one satellite connection link is obtained based on the at least two satellite nodes, and the satellite transmission network is obtained by constructing based on the at least one satellite connection link.

[0064] In a specific implementation, the satellite operation cycle is divided to obtain the satellite network dynamic topology information:

[0065] As a specific embodiment, according to the motion law of the satellite, the operation cycle S of the satellite is divided into m segments [s0=0, s1], [s1, s2], L, [s m -1,s m = S]; Assuming that the satellite network topology does not change in each time period, these m time periods represent m different network topologies. Each topology will be stored by the satellite, and link switching and topology changes only occur in s0, s1, ..., s m endpoint.

[0066] During specific implementation, the satellite node:

[0067] Satellite nodes refer to satellites that serve as communication relay points in a satellite communication network; these satellites are equipped with communication equipment and can transmit data between the earth and other satellites or directly with ground stations.

[0068] In specific implementation, the satellite transmission network:

[0069] As a specific embodiment, in this solution, the satellite transmission network is represented by an undirected graph F = (U, D, V). U = L × M means there are L tracks in total, each track has M satellites, where U is the number of satellite nodes in the network. D = {d(h, i) | h, i∈U} represents the connection status of two adjacent satellites, which is the set of all links between satellites. V = {v(u h ,u i )|u h ,u i ∈U} represents satellite node u h to u i The path weight is usually calculated by delay, link length or other communication costs.

[0070] Assume O = {u0, u1, ..., u c |u0,u1,...,u c ∈U} represents the distance from the source satellite node u0 to the destination satellite node u in different networks c If there is a link in the path O, the weight V(O) of path O is:

[0071]

[0072] During the satellite movement, the connection status D(s) of the intersatellite link is as shown in the formula:

[0073]

[0074] The link weight is expressed by the inter-satellite link length V(s), which is specifically expressed as shown in the formula:

[0075]

[0076] In the formula, (M h , M i )∈M,(L h , L i )∈L.

[0077] In the above exemplary embodiment, a method of constructing a satellite transmission network based on the satellite operation cycle is introduced. The following specifically introduces a method of obtaining at least one satellite connection link in the above exemplary embodiment:

[0078] In this exemplary embodiment, constructing based on the at least two satellite nodes to obtain at least one satellite connection link includes:

[0079] In response to satisfying one of the following two conditions, the at least two satellite nodes are constructed to obtain at least one satellite connection link, and the two conditions are: determining the orbital parameters of the at least two satellite nodes, and judging whether the orbital parameters of the two satellite nodes are in the same orbit and adjacent to each other; or, whether the orbital parameters of the two satellite nodes are at adjacent orbital levels and at the same position number.

[0080] In a specific implementation, in response to satisfying one of the following two conditions, the at least two satellite nodes are constructed to obtain at least one satellite connection link, the two conditions being: determining the orbital parameters of the at least two satellite nodes, and judging whether the orbital parameters of the two satellite nodes are in the same orbit and adjacent to each other; or, judging whether the orbital parameters of the two satellite nodes are at adjacent orbital levels and at the same position number:

[0081] Following the above exemplary embodiment, where d h，i (s) represents two satellites u in the network h Whether a link can be established between them is as shown in the formula:

[0082]

[0083] In the formula, (M h , M i )∈M,(L h , L i )∈L.

[0084] In the formula, d(M h , L h )(M i , L i ) represents the two satellites u in the network h and u i The output of this function is a value that determines whether the link is feasible based on the satellite's orbit M and the satellite's position L on the orbit. Specifically:

[0085] When M h =M i And L h ≠L i When ±1, it means that the two satellites are in the same orbit, but they are not adjacent satellites, so a link can be established and the function value is 1.

[0086] When M h =M i ±1, and L h =L i When , it means that the two satellites are in adjacent orbits and their positions in the orbits are the same, so a link can also be established and the value of the function is 1.

[0087] If neither of the above two conditions is met, it means that the two satellites cannot establish a direct link, and the value of the function is infinity (∞), indicating that the link is unavailable.

[0088] Here, M and L represent the orbit of the satellite and its position in the orbit, respectively. h and M i represents the orbits of the hth and ith satellites, L h and L i Indicates their position on the track.

[0089] Step S220: determine the data transmission link of the satellite transmission network, select the data transmission link, and obtain the satellite network transmission path.

[0090] During specific implementation, the data transmission link mode of the satellite transmission network is determined:

[0091] Following the above exemplary embodiment, a satellite is always connected to two adjacent satellites in the same orbit. The connection status with satellites in different orbits needs to be determined based on the relative positions of the two satellites to determine whether the conditions for establishing a connection are met. The radius of the earth is Q, the orbital height of the satellite is g, and the link length between the two satellites is c. If two satellite nodes u h and u i Just one link can be established, and the distance between the two is as follows:

[0092]

[0093] When v h，i =v i，h = c is the maximum link length. When satellite u h and u i No intersatellite link can be established between them, that is, v h，i =v i，h =∞. When When the two satellites are connected, a connection can be established, and the link length varies over time.

[0094] In the above exemplary embodiment, a method of determining a data transmission link of the satellite transmission network is introduced. Next, a method of constructing at least one objective function is introduced:

[0095] In this exemplary embodiment, determining the link connection state of the data transmission link, obtaining link transmission performance parameters based on the link connection state, and constructing at least one objective function based on the link transmission performance parameters include:

[0096] Determine a link connection state of the data transmission link, obtain link transmission performance parameters based on the link connection state, and construct at least one objective function based on the link transmission performance parameters.

[0097] In specific implementation, the link connection status is:

[0098] The link connection status includes the end-to-end delay, connection status, remaining bandwidth, etc. of the intersatellite link. Since the energy of each node in the satellite communication network is limited, the remaining energy and communication overhead of the satellite are also included in the constraints of routing selection.

[0099] In specific implementation, the link transmission performance parameters include:

[0100] The total delay of the path from the source satellite node to the destination satellite node, the remaining energy of the satellite node, and the available bandwidth for data transmission.

[0101] In a specific implementation, based on the link connection state, a method of obtaining link transmission performance parameters is as follows:

[0102] The end-to-end delay between two satellite nodes consists of the data transmission delay and the link queuing delay. The total delay C of the path O from the source satellite node h to the destination satellite node i is o As shown in the formula:

[0103] C o =t1S o +t2P o

[0104] In the formula, S o represents the propagation delay, P o represents the queuing delay, t1 and t2 represent their weights. For the link cost of the satellite network, both are equally important, so t1 = t2 = 0.5.

[0105] The transmission delay of the data packet S o The link length K between two satellite nodes h，i The calculation method is shown in the formula:

[0106]

[0107]

[0108] Instantaneous geocentric angle The calculation formula is as follows:

[0109]

[0110] Among them (α h , α i ) and (β h , βi ) are the longitude and latitude of the two visible satellites.

[0111] Link queuing delay P o The calculation formula is as follows:

[0112]

[0113] Where: m h represents the number of data packets to be forwarded at node h in the path, wk represents the average length of the data packets, and A is the transmission bandwidth.

[0114] Assuming that the energy consumed by a node to process and transmit a unit of data is unit 1, the remaining energy X of the satellite node can be obtained through real-time updates. The total communication overhead B o Including link transmission overhead B o (d) and node information processing overhead B o (u), the calculation formula is as shown in the formula:

[0115] B o =∑B o (d)+∑B o (u)

[0116] In terms of load balancing, the smaller the communication overhead, the larger the residual energy, and the better the network performance.

[0117] For a communication path O, its available bandwidth A o is the difference between the total link bandwidth and the used link bandwidth, as shown in the formula:

[0118] A o =min d∈o {A total (d)-A used (d)}

[0119] In the formula, A total (d) is the total link bandwidth, A used (d) is the used link bandwidth.

[0120] Compare the remaining bandwidth on each link and take the smallest link remaining bandwidth as the available bandwidth of path O.

[0121] In a specific implementation, at least one objective function is constructed based on the link transmission performance parameters:

[0122] Following the above exemplary embodiments, based on X h , A h and C h The three constraint indicators construct the objective function E(h), as follows:

[0123]

[0124] In the formula, l1, l2, l3 are A h , X h , C h The corresponding weight coefficients, the sum of the weight coefficients is 1.

[0125] In the above exemplary embodiments, a method for obtaining link transmission performance parameters is introduced. Next, a method for obtaining a satellite network transmission path is introduced:

[0126] In this exemplary embodiment, the data transmission link is selected based on the at least one objective function to obtain the satellite network transmission path, including:

[0127] The at least one objective function is compared to obtain a minimum objective function; the data transmission link is selected based on the minimum objective function to obtain the satellite network transmission path.

[0128] In a specific implementation, the at least one objective function is compared to obtain a minimum objective function; the data transmission link is selected based on the minimum objective function to obtain the satellite network transmission path:

[0129] Following the above exemplary embodiment, for satellite routing selection, when the link is connected, it is necessary to select a satellite with low end-to-end delay, large remaining bandwidth, and high remaining energy:

[0130]

[0131] where o∈(o1, ~L, O m )∈P represents a set of paths. In addition, A min Indicates the minimum available bandwidth that meets the transmission conditions. min represents the minimum remaining energy that meets the transmission conditions, and c represents the maximum length of the inter-satellite link.

[0132] After finding multiple next-hop forwarding paths, the objective function values ​​of these paths are input into the minimum heap optimized priority queue. The priority queue will automatically sort and take out the minimum element at the head of the queue. The path corresponding to the minimum value taken out is the shortest forwarding path for the next hop. The Dijkstra algorithm is then used for calculation. The time complexity of the Dijkstra algorithm combined with the minimum heap optimization is reduced to R (PlogL), (L represents the number of vertices, and P represents the total number of edges), so as to form the optimal forwarding path for data transmission.

[0133] Step S230, determine the Shagohuang area electricity business data packet, and transmit the Shagohuang area electricity business data packet to the client based on the satellite network transmission path.

[0134] In this exemplary embodiment, power data is collected in the Shagohuang area to obtain a power business data packet in the Shagohuang area, including:

[0135] During the specific implementation, the method of determining the power business data package in the Shagohuang area is as follows:

[0136] The power line carrier and power wireless are combined to collect the data packets of the power business in Shagohuang area to the server. The power line carrier and power wireless can make full use of the existing power lines for data transmission, and at the same time expand the coverage and flexibility through wireless technology, realize wider network deployment, improve data transmission speed and communication reliability, reduce wiring costs, and adapt to various complex environments.

[0137] In the above exemplary embodiment, a method for determining the power service data packet in the Shagohuang area is introduced. Next, a method for transmitting the power service data packet in the Shagohuang area to the client is introduced:

[0138] In this exemplary embodiment, the transmission of the Shagohuang area power service data packet to the client based on the satellite network transmission path includes:

[0139] The Shagohuang area electricity business data packet is encrypted to obtain an encrypted electricity data packet, the encrypted electricity data packet is transmitted to a satellite command machine, the Shagohuang area electricity business data packet decrypted by the satellite command machine is received, and the Shagohuang area electricity business data packet is transmitted to the client.

[0140] The information processed by the server is sent to the satellite data collector, and the relevant content is sent to the satellite user terminal according to the format of the satellite communication application protocol. The satellite user terminal encrypts the data and sends the information to the satellite; after the satellite receives the communication message, it forwards the information to the satellite command machine on the ground; then, the satellite command machine decrypts the received data and sends the processed data to the server, and the server sends the information to the client.

[0141] Based on the above exemplary embodiments, the correlation characteristics between constellation types and links can be discovered. Aiming at the routing optimization problem of satellite-ground fusion network, the end-to-end delay law of satellite-ground fusion network and the evolution mechanism of satellite dynamic link state are explored, and a multi-objective routing optimization algorithm for satellite-ground fusion network based on improved Dijkstra algorithm is proposed. Before sending a data packet, the connection status between satellite nodes in the constellation is first determined according to the current network topology, and then a source satellite node u is determined. h, and select the next hop shortest path according to the constraints. However, with the dynamic changes of the satellite, when information is sent to a certain node, the connection status of the satellite node and other nodes may change, and the transmission path will also change. At the same time, due to the changes in residual energy and residual bandwidth, the network topology of the constellation will also change. Therefore, when a data packet is forwarded to a certain hop node, it is necessary to update the connection status, residual energy and residual bandwidth of the adjacent nodes, calculate the new objective function value, and select a new shortest path for forwarding.
