Problems solved by technology

[0004] The following problems exist in the routing selection in the existing UAV ad hoc network. The OLSR routing protocol has multiple available routes between the source node and the destination node. In the scenario, it does not take into account the high mobility of the UAV and the impact of the communication distance on the communication, and the selected link is often very easy to break; because the UAV load is limited, the battery energy it carries cannot be too large, so the The dependence on energy is high, and the MPR node in the OLSR routing protocol, even if it does not communicate, still needs to forward TC packets, and the energy of the node will be exhausted soon, causing the link to be interrupted
