[0002] An ad hoc network is a type of network that has no central control nodes, each node can move freely, the nodes can configure the network autonomously, and can dynamically route. The main feature of an ad hoc network is that it has the ability to self-organize and self-configure. It can automatically form a network and realize communication between nodes without any preset network infrastructure. Therefore, ad hoc network technology has been widely used in battlefield communications, disaster relief sites, scientific research detection and other fields.

[0003] In a complex electromagnetic environment, such as a battlefield environment, due to various electromagnetic interferences and the dynamic movement of nodes, the network parameters of the ad hoc network, such as working frequency, working ID, signal bandwidth, communication distance, etc., need to be adjusted frequently to adapt to environmental changes and optimize network performance.

[0026] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In order to more clearly understand the various embodiments provided by the present invention, the technical content involved in the present invention is first introduced as follows.

[0028] In traditional ad hoc networking technology, if an offline node wants to reconnect to the ad hoc network, it usually needs to obtain the latest network parameters through some external means, such as manual settings or preset interaction protocols. However, these methods have many limitations in practical applications. For example, manual settings require human intervention and may not be implemented in emergency or dangerous situations; and preset interaction protocols may be affected by factors such as electromagnetic interference and cannot work properly.

[0029] Based on the above shortcomings, the present invention proposes a new automatic re-entry mechanism for an ad hoc network, which enables offline nodes or newly added nodes to automatically re-enter the ad hoc network without obtaining network parameters in other ways.

[0030] Combine the following Figure 1-Figure 7 The present invention describes the access method and device of the ad hoc network.

[0031] Figure 1 It is one of the flow diagrams of the access method of the self-organizing network provided by the present invention, the method is applied to the node to be accessed in the self-organizing network system, the self-organizing network system includes at least one current node and the node to be accessed; Figure 1 As shown, the method includes the following: Step 101, based on the initial working parameters of the node to be accessed, receiving data transmitted in the ad hoc network system; the node to be accessed is an off-network node or a new node; the initial working parameters of the node to be accessed are working parameters corresponding to the initial network parameters of the ad hoc network system; the number of total time slots in the ad hoc network system is greater than or equal to the number of current nodes in the ad hoc network system, the total time slots include a first time slot, the first time slot is a time slot for data transmission based on the initial network parameters, and the data transmitted in the first time slot includes at least the latest network parameters corresponding to the ad hoc network system; Specifically, it should be noted that the executor of the present invention is a node to be accessed in a self-organizing network system. The node to be accessed is a node that needs to access the self-organizing network. The present invention is used to enable disconnected nodes or new nodes to automatically reconnect to the self-organizing network in a complex electromagnetic environment.

[0032] The self-organizing network system includes at least one current node and a node to be connected. Figure 2 It is one of the structural diagrams of the self-organizing network system provided by the present invention, such as Figure 2 As shown, the ad hoc network system includes N current nodes, such as node 1, node 2, node 3, ... node N, and nodes to be accessed, such as offline nodes or new nodes.

[0033] The number of total time slots of the self-organizing network system in the present invention is greater than or equal to the number of current nodes in the self-organizing network system, and the total time slots include the first time slot, which is a time slot for data transmission based on the initial network parameters, and the data transmitted in the first time slot includes at least the latest network parameters corresponding to the self-organizing network system. Exemplarily, a new time slot is additionally set up on the basis of the original N time slots (time slots) in the self-organizing network system in the present invention, namely, the N+1th time slot. The first N time slots transmit data according to the new network parameters (such as state B); the N+1th time slot uses the initial network parameters (such as state A) for data transmission, and the content transmitted includes the latest parameter information of the current network (such as state B).

[0034] The node to be connected receives the data transmitted in the self-organizing system based on the initial working parameters of the node to be connected. Among them, the node to be connected (offline node or new node) uses the initial network parameters (state A) by default for reception, so it can definitely receive the data transmitted in the N+1th time slot, that is, it can receive the latest parameter information of the current network (such as state B) through the N+1th time slot.

[0035] Figure 3 This is the second structural diagram of the self-organizing network system provided by the present invention, such as Figure 3 As shown, Figure 3 Represents a time division multiple access TDMA frame. A frame may consist of multiple groups of time slots, and the structure of each group is the same. Take #1 as an example, it includes user access time slots of 1 to N nodes, and a parameter time slot is added after the user access time slot. This parameter time slot will use the broadcast mode, apply the initial factory parameters (state A) to transmit new parameters (state B).

[0036] Step 102: When it is determined that the latest network parameters of the ad hoc network system are received, the initial working parameters are adjusted based on the latest network parameters to obtain adjusted working parameters; the adjusted working parameters are determined based on the latest network parameters; Specifically, after receiving the information of the N+1th time slot, the latest parameters of the current network (such as state B) can be obtained, so that the parameters of the device itself can be automatically adjusted based on the latest network parameters to re-access the network.

[0037] For example, the initial working parameters of the access node are first adjusted based on the latest network parameters to obtain adjusted working parameters. The adjusted working parameters are determined based on the latest network parameters and can adapt to the latest current network environment.

[0038] Step 103: Access the ad hoc network system based on the adjusted working parameters.

[0039] Specifically, after the adjusted working parameters are obtained, the adjusted working parameters can adapt to the latest current network environment, and then the self-organizing network system can be accessed based on the adjusted working parameters, that is, automatic access to the self-organizing network can be achieved.

[0040] Through this mechanism, whether it is parameter adjustment caused by electromagnetic interference or disconnection caused by node movement, the node can automatically reconnect to the network if the network access conditions are met, thereby improving the stability and flexibility of the network.

[0041] The method provided in this embodiment is applied to a node to be accessed in a self-organizing network system, and the self-organizing network system includes at least one current node and a node to be accessed. First, based on the initial working parameters of the node to be accessed, data transmitted in the self-organizing network system is received, wherein the node to be accessed is an offline node or a new node, and the initial working parameters of the node to be accessed are working parameters corresponding to the initial network parameters of the self-organizing network system. The total number of time slots in the self-organizing network system is greater than or equal to the number of current nodes in the self-organizing network system, and the total time slots include a first time slot, which is a time slot for data transmission based on the initial network parameters, and the data transmitted in the first time slot includes at least the latest network parameters corresponding to the self-organizing network system; then, when it is determined that the latest network parameters of the self-organizing network system are received, the initial working parameters are adjusted based on the latest network parameters to obtain adjusted working parameters, wherein the adjusted working parameters are determined based on the latest network parameters; based on the adjusted working parameters, the self-organizing network system is accessed.

[0042] In the present invention, because the number of total time slots in the self-organizing network system is greater than or equal to the number of current nodes in the self-organizing network system, the total time slot includes a first time slot, which is a time slot for data transmission based on the initial network parameters, and the transmitted data at least includes the latest network parameters corresponding to the self-organizing network system, and the initial working parameters of the node to be accessed are the working parameters corresponding to the initial network parameters of the self-organizing network system. The node to be accessed can receive the latest network parameters, and then adjust the working parameters based on the latest network parameters received from the self-organizing network system, and automatically re-access the self-organizing network system based on the adjusted working parameters. The present invention can ensure that in a dynamically changing self-organizing network environment, whether it is a node that is disconnected from the network or a newly added node, it can quickly obtain the current latest network parameters and adjust its own parameters to quickly access the self-organizing network, thereby improving the flexibility and robustness of the self-organizing network, and realizing that the node or new node that is disconnected from the network in a complex electromagnetic environment can automatically re-access the self-organizing network.

[0043] According to a method for accessing an ad hoc network provided by the present invention, based on the initial working parameters of the node to be accessed, before receiving data transmitted in the ad hoc network system, the method further includes: Determine the total number of time slots in the ad hoc network system according to the number of current nodes in the ad hoc network system; The total time slot also includes a second time slot, which corresponds to each current node. The time slot of the second time slot is a time slot for data transmission based on the latest network parameters.

[0044] Specifically, in some embodiments, before step 102 receives data transmitted in the self-organizing network system based on the initial working parameters of the node to be accessed, it also includes: According to the number of current nodes in the ad hoc network system, the total number of time slots in the ad hoc network system is determined. Since the total number of time slots in the ad hoc network system is greater than the number of current nodes, if the current number of nodes is N, the total number of time slots is N+1, that is, a new time slot is set up in the ad hoc network system based on the original N time slots (time slots), that is, the N+1th time slot. The first N time slots transmit data according to the new network parameters (such as state B); the N+1th time slot uses the initial network parameters (such as state A) for data transmission, and the content transmitted includes the latest parameter information of the current network (such as state B).

[0045] The total time slot in the ad hoc network system also includes a second time slot, which corresponds to each current node. The time slot of the second time slot is a time slot for data transmission based on the latest network parameters. If there are N current nodes, the first N time slots are the second time slots, and the first N time slots are used for data transmission according to the new network parameters (such as state B).

[0046] The method provided in this embodiment mainly utilizes the dynamic time slot allocation method to add a specific broadcast time slot to propagate the current working parameters of the self-organizing network. This mechanism is applied to the rapid re-entry of offline nodes or newly joined nodes. Even when the node cannot obtain the current network parameters through other means, it can obtain the network parameters according to this specific broadcast time slot, thereby realizing automatic re-entry into the network and restoring network communication.

[0047] According to an access method of an ad hoc network provided by the present invention, based on the initial working parameters of a node to be accessed, data transmitted in the ad hoc network system is received, comprising: Based on the initial working parameters of the node to be accessed, receiving the data transmitted in the first time slot; Determining whether the data transmitted in the first time slot includes the latest network parameters corresponding to the ad hoc network system; When it is determined that the data transmitted in the first time slot includes the latest network parameters corresponding to the ad hoc network system, it is determined that the latest network parameters of the ad hoc network system are received.

[0048] Specifically, in some embodiments, step 101 may be implemented by the following steps: It can be understood that, since the initial working parameters of the node to be accessed are determined based on the initial network parameters, and the first time slot performs data transmission based on the initial network parameters, the node to be accessed can receive the data transmitted in the first time slot.

[0049] Furthermore, the data transmitted in the first time slot includes the latest network parameters corresponding to the self-organizing network system. When the node to be accessed determines that the data transmitted in the first time slot includes the latest network parameters corresponding to the self-organizing network system, it determines that the latest network parameters of the self-organizing network system have been received. Subsequently, the node can adjust its own working parameters based on the latest network parameters to achieve re-access to the self-organizing network.

[0050] The method provided in this embodiment can obtain the network parameters according to this specific broadcast time slot even when the node to be accessed cannot obtain the current network parameters through other means, thereby achieving automatic re-entry into the network and restoring network communication.

[0051] According to a method for accessing a self-organizing network provided by the present invention, the latest network parameters include at least one of the following: network working mode, network device interface requirements, supported frequency bands, output frequency, working ID, signal bandwidth and communication distance; the adjusted working parameters include at least one of the following: node type, node address, node status, power and working frequency band.

[0052] Specifically, in some embodiments, the latest network parameters include at least one of the following: network operating mode, network device interface requirements, supported frequency bands, output frequency, operating ID, signal bandwidth, and communication distance.

[0053] Among them, the working mode of the network refers to that the self-organizing network device can work in the self-organizing network mode, LTE public network mode or LTE private network mode, and supports multi-mode single-pass. Supported frequency band: refers to the frequency band supported by the self-organizing network device, such as 566-678MHz or 1420-1530MHz, as well as the frequency bands of LTE public network and private network. Output power: refers to the output power of the self-organizing network device, such as 33 dBm *2. The latest network parameters also include: 1. Technical system: wireless self-organizing network technology based on LTE-A. 2.

Voice: supports PTT voice intercom, voice conferencing and other functions.

[0054] The adjusted working parameters include at least one of the following: node type, node address, node status, power and working frequency band.

[0055] Among them, node type: refers to the role of the node in the network, such as terminal node or routing node. Node address: refers to the unique identifier of each node, which is used to indicate the location and communication relationship of the node in the network. Node status: refers to the operating status of the node, such as idle state or active state. Power: refers to the strength of wireless signal propagation. The appropriate power can be selected according to the network environment.

[0056] The latest network parameters of the method provided in this embodiment include at least one of the following: network working mode, network device interface requirements, supported frequency bands, output frequency, working ID, signal bandwidth and communication distance; the adjusted working parameters include at least one of the following: node type, node address, node status, power and working frequency band; the node to be accessed adjusts its own parameters according to the latest network parameters received to achieve automatic access to the ad hoc network.

[0057] According to a method for accessing an ad hoc network provided by the present invention, based on adjusted working parameters, accessing an ad hoc network system includes: Based on the network device interface requirements of the ad hoc network system, configure the corresponding interface parameters; Determine wireless signal parameters according to the network output power and supported frequency band of the ad hoc network system; the wireless signal parameters include power and working frequency band; Configure the node parameters of the node to be connected; the node parameters include node type, node address and node status; Based on interface parameters, wireless signal parameters and node parameters, the ad hoc network system is joined through the routing protocol and mechanism of the ad hoc network system.

[0058] Specifically, in some embodiments, the specific implementation process of accessing the ad hoc network system based on the adjusted working parameters in step 104 includes the following steps: First, based on the network device interface requirements of the ad hoc network system, configure the corresponding interface parameters, such as Ethernet, USB, and RF interface.

[0059] Further, the wireless signal parameters are determined according to the network output power and supported frequency band of the ad hoc network system, and the wireless signal parameters include power and working frequency band. For example, the wireless signal parameters of the self-ad hoc network system, including power and working frequency band, are adjusted according to the network output power and supported frequency band to achieve the best wireless signal propagation effect.

[0060] Furthermore, the node parameters of the node to be connected are configured to ensure that the node can correctly locate and communicate in the network. The node parameters include node type, node address and node status.

[0061] Furthermore, based on the interface parameters, wireless signal parameters and node parameters, the ad hoc network system is joined through the routing protocol and mechanism of the ad hoc network system.

[0062] The method provided in this embodiment, through the above steps, the node to be connected can adjust its own working parameters based on the latest network parameters to successfully access the ad hoc network and participate in network communication. The proposal and implementation of this mechanism not only improves the network stability and robustness of the ad hoc network, but also greatly improves the network utilization efficiency and adaptability, especially in complex electromagnetic environments such as battlefield environments, which can help nodes that meet the network access conditions to automatically restore communication, thereby helping to improve the speed and efficiency of information transmission and reduce the impact of communication interruptions on combat operations.

[0063] According to an access method of an ad hoc network provided by the present invention, based on interface parameters, wireless signal parameters and node parameters, an ad hoc network system is joined through a routing protocol and mechanism of the ad hoc network system, comprising: Establishing a connection with any first node in the ad hoc network system based on the interface parameters, the wireless signal parameters and the node parameters; Based on the connection with each first node, data is transmitted with the first node to achieve access to the self-organizing network system.

[0064] Specifically, in some embodiments, based on the interface parameters, wireless signal parameters and node parameters, the specific implementation process of joining the ad hoc network system through the routing protocol and mechanism of the ad hoc network system includes the following steps: First, based on the interface parameters, wireless signal parameters and node parameters, a connection is established with any first node in the self-organizing network system. Then, data is transmitted with the first node based on the connection with each first node to achieve access to the self-organizing network system.

[0065] For example, through the routing protocols and mechanisms of ad hoc networks, nodes try to join the network, establish connections with other nodes, and start data transmission. Nodes adjust their routing and communication strategies according to dynamic changes in the network, such as changes in topology, to maintain the stability and connectivity of the network.

[0066] Even if no node in the current network is disconnected, the N+1th time slot will always exist. Even if the new node is not clear about the current network parameters, it can obtain the current network parameters by receiving the information of the N+1th time slot, thereby achieving automatic access.

[0067] The method provided in this embodiment uses the routing protocol and mechanism of the self-organizing network, and the node to be connected attempts to join the network, establishes connections with other nodes, and starts data transmission, so that nodes or new nodes that are disconnected from the network in a complex electromagnetic environment can automatically reconnect to the self-organizing network.

[0068] Figure 4 This is a second flow chart of the method for accessing a self-organizing network provided by the present invention, such as Figure 4As shown, the method includes: Step 401: The off-grid node sets the working parameters to the factory default state A.

[0069] First, the off-grid node sets its working parameters to the factory default state A. These parameters include but are not limited to: working frequency, working ID, signal bandwidth, communication distance, etc.

[0070] Step 402: The off-network node continues to monitor network signals in state A. Since its parameters have been set to state A, it can monitor the network parameter state B information sent using the factory parameter state A in the N+1th time slot.

[0071] Step 403: The offline node receives the broadcast information of the ad hoc network (notifying that the ad hoc network parameter is in the B state).

[0072] Step 404: The offline node adjusts the working state from state A to state B.

[0073] When the offline node receives the network parameter state B information, it will immediately change its own working parameters from state A to the received state B. In this way, the working parameters of the offline node will be consistent with the parameters of other nodes in the current network.

[0074] Step 405: The offline node establishes communication with other nodes.

[0075] The offline node starts to communicate with other nodes in the network according to the new network parameter state B to reconnect to the network.

[0076] Step 406: The offline node rejoins the network.

[0077] The method provided in this embodiment can effectively achieve the rapid reconnection of disconnected nodes in an ad hoc network without manual intervention or other external means. By setting a specific parameter transmission time slot and allowing the disconnected node to adjust the parameters after receiving the new network parameters, the network reconnection of the node can be completed in a short time, thereby improving the stability and operation efficiency of the network. This is particularly important in a rapidly changing and complex electromagnetic environment, such as in a battlefield environment.

[0078] Figure 5 FIG. 3 is a flow chart of the access method of the self-organizing network provided by the present invention. Figure 5 As shown, the method includes: Step 501: The new node sets the working parameters to the factory default state A.

[0079] First, the new node sets its operating parameters to the factory default state A. These parameters include but are not limited to: operating frequency, operating ID, signal bandwidth, communication distance, etc.

[0080] Step 502: The new node continues to monitor network signals in state A. Since its parameters have been set to state A, it can monitor the network parameter state B information sent using the factory parameter state A in the N+1th time slot.

[0081] Step 503: The new node receives the broadcast information of the ad hoc network (notifying that the ad hoc network parameter is in the B state).

[0082] Step 504: The new node adjusts the working state from state A to state B.

[0083] When the new node receives the network parameter state B information, it will immediately change its own working parameters from state A to the received state B. In this way, the working parameters of the new node will be consistent with the parameters of other nodes in the current network.

[0084] Step 505: The new node establishes communication with other nodes.

[0085] The new node starts to communicate with other nodes in the network according to the new network parameter state B to re-access the network.

[0086] Step 506: The new node rejoins the network.

[0087] The method provided in this embodiment enables the new node to quickly obtain the working parameters of the current ad hoc network and adjust its own working state according to these parameters, thereby smoothly accessing the network. This process is not only fast but also simple, and the new node can access the network without knowing the detailed configuration parameters of the network in advance. This is extremely important for the dynamically adjusted ad hoc network environment, especially in the battlefield and other environments that require rapid response, which can significantly improve the real-time performance and flexibility of the network.
