Abstract

To address the topological instability in the amorphous flat air-ground wireless self-organizing network caused by the high-speed movement of the network nodes, this paper adopts the 802.15.4 protocol as the basis of research, and uses dynamic planning in optimal control theory to backpropagate and optimize the directional steering angle of the mobile trajectories of the air and ground self-organizing nodes, so as to maximize the elimination of the wireless signal coverage blind area and enable as many self-organizing nodes as possible to form a stable, effective and reliable self-organizing network topology. This can maximize the elimination of wireless signal coverage blind areas and enable as many selfassembling nodes as possible to form a stable, effective and reliable self-assembling network topology. The simulation results show that by using the dynamic planning strategy, the optimized steering angle of the moving trajectory direction corresponding to the self-grouping nodes at different moving speeds can be obtained, and the sum of squares of the steering angles of the instantaneous moving trajectory direction of the optimized nodes can be obtained. The experimental results show that three fixed ground self-grouping nodes, one vehicle self-grouping node and one air self-grouping node are used to test the topology of high-speed mobile self-grouping network, and the five nodes can finally form a stable and effective self-grouping network topology.
