Description

Technical Field

[0001] The invention relates to the field of rapid networking of intercoms, and in particular to a rapid networking system of portable intercoms. Background Art

[0002] In traditional portable walkie-talkie systems, networking mainly relies on fixed relay stations or base stations for signal forwarding, which greatly limits the communication range and system stability. Especially in complex environments such as mountains and urban buildings, fixed base stations or relay stations have blind spots in signal coverage, which can easily lead to problems such as signal attenuation and communication interruption. In areas with dense communications, limited spectrum resources are used by a large number of devices at the same time, resulting in serious channel interference, affecting communication quality and data transmission rate. In addition, portable walkie-talkie devices are usually powered by batteries, and node energy is limited. How to ensure network performance while extending the use time of the device is a key issue in wireless network design.

[0003] Based on the above technical challenges, a solution combining node adaptive role allocation, dynamic multi-path establishment, channel aggregation and dispersion strategy, and cross-layer optimization is proposed to solve the problems of rapid networking and efficient communication of portable walkie-talkies in complex environments. Summary of the invention

[0004] In order to solve the above technical problems, a portable walkie-talkie rapid networking system is provided. This technical solution solves the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the present invention is:

[0006] A portable intercom rapid networking system, comprising: a node adaptive role allocation module, wherein the node adaptive role allocation module adaptively allocates node roles according to the location information of each intercom node in the system, combined with the signal strength and remaining power of the node;

[0007] A path dynamic adjustment module, wherein the path dynamic adjustment module establishes a preliminary path by issuing a path request, and dynamically calculates the comprehensive quality of the path based on the node information in each path to dynamically adjust the path priority;

[0008] A channel aggregation and dispersion strategy adjustment module, which identifies the occupancy and interference level of each channel based on real-time spectrum detection, and automatically performs dynamic switching adjustment of the channel aggregation or dispersion strategy;

[0009] A communication cross-layer coordination module, wherein the communication cross-layer coordination module dynamically adjusts transmission parameters to achieve communication cross-layer coordination according to the status monitoring information of the physical layer, data link layer and network layer after the intercom is networked.

[0010] Preferably, the node adaptive role allocation module adaptively allocates node roles according to the location information of each intercom node in the system in combination with the signal strength and remaining power of the node, specifically including:

[0011] Define the intercom rapid networking area, and obtain the real-time geographic location information of each intercom node through the positioning module in the intercom. The node location is expressed as (x i ,y i ) means, (x i ,y i ) is the corresponding specific coordinates of the node longitude and latitude after Mercator projection conversion;

[0012] Set the node signal monitoring frequency, set the transmission power and actual distance between the monitoring nodes, and calculate the signal strength between the monitoring nodes as a measure of link quality. The signal strength is calculated as follows: Where S ij (t) represents the signal strength between node i and its adjacent jth node at time t, P t Set the transmit power for the radio, d ij (t) is the Euclidean distance between the coordinates of node i and its adjacent jth node, γ is the path loss factor;

[0013] According to the remaining power of each node and the expected energy consumption in the current communication task, a weighted comprehensive operation is performed in combination with the calculated average signal strength of each node and its adjacent nodes to comprehensively evaluate the adaptability of the node as a relay node;

[0014] A relay node adaptability threshold is set, and the node roles reaching the relay node adaptability threshold are marked as candidate relay nodes, and the node roles below the relay node adaptability threshold are marked as ordinary nodes.

[0015] Preferably, the path dynamic adjustment module establishes a preliminary path by issuing a path request, and dynamically calculates the comprehensive quality of the path based on the node information in each path to dynamically adjust the path priority, specifically including:

[0016] The system sends out path requests through the AODV protocol, and each node responds and reports its role, signal strength, location, and energy level;

[0017] The system screens the received response information and gives priority to the devices marked as standby relay nodes in the adaptive role allocation. When multiple standby relay node devices appear in the path, it makes concurrent path requests and builds multiple communication paths based on the selected nodes.

[0018] Multiple communication paths are analyzed separately, and the comprehensive quality of the path is dynamically calculated based on the link quality and energy level in the path. The calculation method is:

[0019]

[0020] In the formula, LQ c is the link quality of the cth node, is the average signal strength of the cth node and its neighboring nodes, PLR c is the packet loss rate of the cth node, E rem,c 、E total,c are the residual energy and total energy of the cth node, α and β are the calculation weight coefficients of link quality and residual energy ratio, Q path is the comprehensive quality of the path, which is used to evaluate the quality of the path, and n is the total number of nodes in the path;

[0021] After the path is established and evaluated, the system prioritizes each path according to the ratio of the comprehensive quality of the path to the number of path hops, selects the path with the highest priority as the active path, and the remaining paths as backup paths;

[0022] Whenever a new node is added or the status of an existing node changes, the system recalculates the priority and dynamically adjusts the order in which paths are used.

[0023] Preferably, the channel aggregation and dispersion strategy adjustment module identifies the occupancy and interference level of each channel according to real-time spectrum detection, and automatically performs dynamic switching adjustment of the channel aggregation or dispersion strategy, specifically including:

[0024] The system performs a full-band scan of the radio's communication channel to detect the channel's idle state, interference intensity, and available bandwidth, and evaluates the channel's availability through an extended channel perception function.

[0025] Setting an availability evaluation value threshold for each channel, and marking a channel whose availability evaluation value is higher than the availability evaluation value threshold as a policy adjustment channel;

[0026] Monitor the intercom communication network in real time. If a channel whose transmission traffic in the communication network reaches the preset saturation ratio of a single channel bandwidth is detected, the channel will be marked as a busy channel. If a channel whose interference intensity exceeds the preset risk interference level is detected, the channel will be marked as an interference channel.

[0027] When a busy channel is detected, the system triggers the channel aggregation strategy. The system selects m available strategy-adjusted channels that are close to each other for aggregation and calculates the effective total bandwidth after aggregation. The calculation formula for the effective total bandwidth of the aggregated channel is:

[0028]

[0029] Where, BW aggis the effective total bandwidth after channel aggregation, BW u is the bandwidth of the u-th channel, I u is the interference intensity of the u-th channel, k is the factor of interference attenuation on bandwidth, and m is greater than or equal to 0;

[0030] When an interference channel is detected, the system triggers the channel dispersion strategy. The system uses a data stream load balancing algorithm to distribute the data stream to o independent available strategy adjustment channels to reduce the congestion or interference impact of a single channel. The load dispersion formula is:

[0031]

[0032] Where, LCH v is the allocated load of the vth channel, D total is the total amount of data, I v is the interference intensity of the vth channel, and o is greater than or equal to 0;

[0033] When all busy channels and interference channels are detected to have disappeared, the channel strategy adjustment is terminated.

[0034] Preferably, the communication cross-layer coordination module dynamically adjusts the transmission parameters to achieve communication cross-layer coordination according to the physical layer, data link layer and network layer status monitoring information after the intercom is networked, specifically including:

[0035] Calculate the current signal availability by monitoring the physical layer signal strength indication and interference monitoring value;

[0036] By monitoring the link layer bandwidth and delay parameters, the link transmission quality of the current data link layer is calculated based on the relationship between bandwidth, signal-to-noise ratio and data packet loss rate;

[0037] By monitoring the number of hops, delay and energy consumption at the network layer, combined with the feedback from the physical layer and the status monitoring information of the data link layer, the optimal path is dynamically selected;

[0038] The system integrates information from the physical layer, data link layer, and network layer, adjusts the collaboration between different layers according to the current transmission status, and dynamically adjusts the overall transmission parameters of the network, including the network layer path selection strategy, the link layer bandwidth allocation, and the physical layer transmission power.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] The adaptive role allocation module determines whether each walkie-talkie can act as a relay node when it starts. This mechanism ensures load balancing in the network, especially avoiding nodes with exhausted energy from continuing to undertake relay tasks, improving the flexibility and durability of the entire network. The path dynamic adjustment module allows the system to establish multiple feasible communication paths at the same time. Once a path fails due to interference or node movement, the system can quickly switch to other available paths to ensure uninterrupted communication. The channel aggregation and dispersion strategy module automatically aggregates or dynamically switches channels to adapt to the transmission requirements of large amounts of data and extreme usage scenarios of single channel overload and frequent conflicts. Through the coordination of cross-layer information, the communication cross-layer coordination module enables the system to dynamically adjust communication parameters to achieve the optimal configuration of overall network performance and improve communication reliability.

[0041] It realizes the fast and reliable networking needs of walkie-talkies to quickly realize network self-organization without fixed infrastructure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0047] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0048] Reference Figure 1 As shown, a portable intercom rapid networking system includes:

[0049] A node adaptive role allocation module, which adaptively allocates node roles according to the location information of each intercom node in the system, combined with the signal strength and remaining power of the node;

[0050] A path dynamic adjustment module, wherein the path dynamic adjustment module establishes a preliminary path by issuing a path request, and dynamically calculates the comprehensive quality of the path based on the node information in each path to dynamically adjust the path priority;

[0051] A channel aggregation and dispersion strategy adjustment module, which identifies the occupancy and interference level of each channel based on real-time spectrum detection, and automatically performs dynamic switching adjustment of the channel aggregation or dispersion strategy;

[0052] A communication cross-layer coordination module, wherein the communication cross-layer coordination module dynamically adjusts transmission parameters to achieve communication cross-layer coordination according to the status monitoring information of the physical layer, data link layer and network layer after the intercom is networked.

[0053] Reference Figure 2 As shown, the node roles are adaptively allocated according to the location information of each walkie-talkie node in the system and the signal strength and remaining power of the node.

[0054] In the scheme, each intercom adaptively decides whether to act as a relay node based on signal strength, node location and remaining energy when it starts up. This mechanism ensures load balancing in the network, especially preventing nodes with exhausted energy from continuing to take on relay tasks, thus improving the flexibility and durability of the entire network.

[0055] Define the intercom rapid networking area, and obtain the real-time geographic location information of each intercom node through the positioning module in the intercom. The node location is expressed as (x i ,y i ) means, (x i ,y i ) is the corresponding specific coordinates after the node longitude and latitude are transformed into Mercator projection. The specific calculation method is:

[0056] Where R is the radius of the earth, λ is the longitude, and φ is the latitude;

[0057] Set the node signal monitoring frequency, set the transmission power and actual distance between the monitoring nodes, and calculate the signal strength between the monitoring nodes as a measure of link quality. The signal strength is calculated as follows: Where S ij (t) represents the signal strength between node i and its adjacent jth node at time t, P t Set the transmit power for the radio, d ij(t) is the Euclidean distance between the coordinates of node i and its adjacent jth node, γ is the path loss factor, which usually takes a value between 2 and 4, depending on the environment (such as city, suburb, open area, etc.). The more complex the environment scene, the larger its value.

[0058] According to the remaining power of each node and the expected energy consumption in the current communication task, a weighted comprehensive operation is performed in combination with the calculated average signal strength of each node and its adjacent nodes to comprehensively evaluate the adaptability of the node as a relay node. The specific calculation method is: Z represents all the node pairs (or links) involved in the communication path from the source node to the target node, D total is the total weighted path distance, and its reciprocal is used as a reference for the relay node adaptability evaluation standard.

[0059] A relay node adaptability threshold is set, and the node roles reaching the relay node adaptability threshold are marked as candidate relay nodes, and the node roles below the relay node adaptability threshold are marked as ordinary nodes.

[0060] Through adaptive role allocation of nodes and dynamic establishment of multiple paths, the system can quickly achieve network self-organization without fixed infrastructure, which is particularly suitable for scenarios such as emergency communications and military missions.

[0061] Reference Figure 3 As shown, a preliminary path is established by issuing a path request, and based on the node information in each path, the comprehensive quality of the path is dynamically calculated to dynamically adjust the path priority.

[0062] The solution allows the system to establish multiple feasible communication paths at the same time. Once a path fails due to interference or node movement, the system can quickly switch to other available paths to ensure uninterrupted communication. By dynamically switching paths, the system can avoid overload or congestion of a single path, thereby effectively reducing data transmission delays and improving overall communication efficiency.

[0063] The system sends out path requests through the AODV protocol, and each node responds and reports its role, signal strength, location and energy level. The AODV protocol here introduces a multi-path mechanism to overcome the limitations of the traditional AODV protocol in highly dynamic self-organizing networks, especially when dealing with anti-interference capabilities and network stability in complex environments. The traditional AODV protocol has some bottlenecks. The traditional AODV only relies on one optimal path, while the improved AODV protocol maintains multiple paths at the same time.

[0064] The system screens the received response information and gives priority to the devices marked as standby relay nodes in the adaptive role allocation. When multiple standby relay node devices appear in the path, it makes concurrent path requests and builds multiple communication paths based on the selected nodes.

[0065] Multiple communication paths are analyzed separately, and the comprehensive quality of the path is dynamically calculated based on the link quality and energy level in the path. The calculation method is:

[0066]

[0067] In the formula, LQ c is the link quality of the cth node, is the average signal strength of the cth node and its neighboring nodes, PLR c is the packet loss rate of the cth node, E rem,c 、E total,c are the residual energy and total energy of the cth node, α and β are the calculation weight coefficients of link quality and residual energy ratio, Q path is the comprehensive quality of the path, which is used to evaluate the quality of the path, and n is the total number of nodes in the path;

[0068] After the path is established and evaluated, the system prioritizes each path according to the ratio of the comprehensive quality of the path to the number of path hops, selects the path with the highest priority as the active path, and the remaining paths as backup paths;

[0069] Whenever a new node is added or the status of an existing node changes, the system recalculates the priority and dynamically adjusts the order of path usage. By dynamically switching paths, the system can avoid overload or congestion of a single path, thereby effectively reducing data transmission delays and improving overall communication efficiency.

[0070] Reference Figure 4 As shown, based on real-time spectrum detection, the occupancy and interference level of each channel are identified, and the channel aggregation or dispersion strategy is automatically and dynamically switched and adjusted.

[0071] The system performs a full-band scan of the radio's communication channel to detect the channel's idle state, interference intensity, and available bandwidth, and evaluates the channel's availability through an extended channel perception function, specifically:

[0072]

[0073] In the formula, C det (f, t) is the channel availability assessment value, I(f, t) is the interference level at a specific frequency f at time t, U(f, t) is the current utilization of the channel, and C det When (f,t) is high, it means that the channel has low interference and low utilization, and is suitable for aggregation or decentralized use. Through continuous detection and real-time evaluation, the system can dynamically select the optimal channel for the next policy operation.

[0074] Setting an availability evaluation value threshold for each channel, and marking a channel whose availability evaluation value is higher than the availability evaluation value threshold as a policy adjustment channel;

[0075] Monitor the intercom communication network in real time. If a channel whose transmission traffic in the communication network reaches the preset saturation ratio of a single channel bandwidth is detected, the channel will be marked as a busy channel. If a channel whose interference intensity exceeds the preset risk interference level is detected, the channel will be marked as an interference channel.

[0076] When a busy channel is detected, the system triggers the channel aggregation strategy. The system selects m available strategy-adjusted channels that are close to each other for aggregation and calculates the effective total bandwidth after aggregation. The calculation formula for the effective total bandwidth of the aggregated channel is:

[0077]

[0078] Where, BW agg is the effective total bandwidth after channel aggregation, BW u is the bandwidth of the u-th channel, I u is the interference intensity of the u-th channel, k is the factor of interference attenuation on bandwidth, and m is greater than or equal to 0;

[0079] When the network requires a high data transmission rate, the system can aggregate multiple channels to provide wider bandwidth to support the transmission needs of large amounts of data. This mechanism can significantly improve the transmission speed and efficiency when transmitting high-priority data.

[0080] When an interference channel is detected, the system triggers the channel dispersion strategy. The system uses a data stream load balancing algorithm to distribute the data stream to o independent available strategy adjustment channels to reduce the congestion or interference impact of a single channel. The load dispersion formula is:

[0081]

[0082] Where, LCH v is the allocated load of the vth channel, D total is the total amount of data, I v is the interference intensity of the vth channel, and o is greater than or equal to 0;

[0083] In an environment with severe interference, the system can disperse data streams to multiple different channels to avoid single-channel overload and frequent conflicts, thereby improving communication stability and anti-interference capabilities.

[0084] When all busy channels and interference channels are detected to have disappeared, the channel strategy adjustment is terminated.

[0085] Reference Figure 5As shown, according to the physical layer, data link layer and network layer status monitoring information after the intercom is networked, the transmission parameters are dynamically adjusted to achieve cross-layer coordination of communication, including:

[0086] The availability of the current signal is calculated by monitoring the signal strength indication and interference monitoring value of the physical layer. The physical layer calculates the availability of the current signal through the signal strength indication (RSSI) and the interference monitoring value. The calculation formula is:

[0087] RSSI eff =RSSI-I noise ;

[0088] Among them, RSSI eff is the effective signal strength, RSSI is the received signal strength, I noise is the detected noise and interference level.

[0089] By monitoring the link layer bandwidth and delay parameters, the link transmission quality of the current data link layer is calculated based on the relationship between bandwidth, signal-to-noise ratio, and data packet loss rate. The specific calculation method is as follows:

[0090]

[0091] Among them, LQ Net is the link transmission quality of the data link layer, BW is the channel bandwidth, SNR is the signal-to-noise ratio, and PLR is the packet loss rate. This formula calculates the transmission quality of the current link through the relationship between bandwidth, signal-to-noise ratio, and data packet loss rate. Net A value of 0 indicates that the link status is good and can support efficient data transmission. A low LQ Net A value of 0 indicates that there may be a problem with the link and optimization adjustment is required.

[0092] By monitoring the number of network layer hops, delay, and energy consumption, combined with physical layer feedback and data link layer status monitoring information, the optimal path is dynamically selected. The path selection process is based on the following formula:

[0093]

[0094] Among them, P opt is the selection coefficient of the optimal path, H a is the number of hops of the ath path, D a is the total delay of the path, E rem,a is the remaining energy of the relay node on the path, and w is the number of optional paths. Through this formula, the system can comprehensively consider the number of hops, delay, and energy factors of each path, and give priority to paths with fewer hops, lower delays, and sufficient relay node energy for data transmission.

[0095] The physical layer provides channel quality feedback, the link layer provides transmission performance data, and the network layer optimizes path selection. Through this cross-layer information collaboration, the system can dynamically adjust communication parameters through cross-layer optimization algorithms to achieve the optimal configuration of overall network performance.

[0096] Flexible algorithms can be used to adjust the overall transmission parameters of the network, such as the gradient descent cross-layer optimization algorithm:

[0097]

[0098] Among them, Opt total is the current cross-layer optimization effect value, Opt prev is the optimization effect value of the last time, η is the learning rate, and controls the adjustment step size. The gradient of each layer parameter is calculated by the gradient descent method. The system can continuously reduce the error terms in the network (such as signal interference, delay, packet loss rate, etc.) and gradually move towards the optimal system configuration. This method can perform continuous optimization in a constantly changing environment and is particularly suitable for performance tuning in complex scenarios.

[0099] Other calculation methods such as dynamic weighting factor adjustment algorithm, cross-layer collaboration optimization method based on game theory, and cross-layer collaboration method based on fuzzy logic are all optional calculation methods and will not be described in detail here.

[0100] The system integrates information from the physical layer, data link layer, and network layer, adjusts the collaboration between different layers according to the current transmission status, and dynamically adjusts the overall transmission parameters of the network, including the network layer path selection strategy, the link layer bandwidth allocation, and the physical layer transmission power, to maximize communication efficiency.

[0101] Furthermore, the present solution also proposes a portable walkie-talkie rapid networking system storage medium, on which a computer-readable program is stored, and when the computer-readable program is called, the above-mentioned portable walkie-talkie rapid networking system is executed.

[0102] It is understandable that the storage medium may be a magnetic medium, such as a floppy disk, a hard disk, or a magnetic tape; an optical medium, such as a DVD; or a semiconductor medium, such as a solid state drive (SSD).
