面向应急通信的无人机自组织网络路由协议研究OA

The emergency communication network,as a key component of post disaster emergency rescue,is commonly used for information exchange between command centers and disaster stricken areas to improve the efficiency of rescue work.In order to achieve real-time transmission of disaster information under extreme conditions such as power outages,circuit breaks,and network disconnections,multiple unmanned aerial vehicles(UAVs)can form a self-organizing network in the air and provide network communication coverage to the affected area.However,due to the high-speed movement of UAVs,the network topology changes rapidly.To address the problem that traditional routing methods cannot adapt to such rapid topology changes,a deep first search based routing algorithm is proposed.The network topology is continuously updated through HELLO messages,and data is forwarded according to the latest topology during routing.When the routing fails,the original path is returned or bypassed through the failed link in a unicast manner to find the destination node.Through simulation experiments,it has been proven that the proposed algorithm can solve the adaptation problem of routing protocols for unmanned aerial vehicles in highly dynamic topologies.Reducing communication latency and increasing data throughput,it have achieved the effect of real-time and stable transmission of disaster information in disaster stricken areas.
