Research On UAV Cluster AD HOC Network Technology Based On Network Connectivity

Compared with the ground MANET network,the UAV cluster ad hoc network has greater flexibility in three-dimensional space,and has important application significance in military and disaster relief scenarios.At the same time,due to the long distance between UAVs,The UAV cluster network is more sparse,the UAV flight speed is higher,and the communication link is prone to interruption and failure.The network topology control needs to consider more factors,and the existing network topology control technology is applied to the UAV cluster self-organization Net has limitations,so it is necessary to study effective topology control based on three-dimensional space.This paper starts from the basic requirements of constructing a drone cluster ad hoc network with certain fault tolerance and survivability,and studies the connectivity of the network.This topic focuses on the construction of a fault tolerance and survivability drone cluster ad hoc network.The topology control algorithm based on network connectivity in the three-dimensional space is used to ensure reliable communication of the UAV cluster ad hoc network by realizing the1-connectivity and 2-connectivity of the topology.details as follows:First,the construction and analysis of the UAV cluster self-organizing network model.This paper firstly analyzes the node model,network topology model and wireless communication channel model of the UAV cluster network,and briefly analyzes the idea of topology movement control of the flying self-organizing network.Second,the UAV cluster self-organizing network 1-connected topology movement control.To be fault-tolerant in a topological network,the connectivity of the network must first be ensured,that is,1-connectivity of the network must be ensured.Based on the Boid algorithm,this topic proposes a network topology movement control algorithm based on mobile buffer,and compares it through simulation.Verifies the obvious advantages of the algorithm in convergence speed and stabilityThird,the UAV cluster self-organizing network 2-connected topology movement control.In this part of the content,this article first proposes a cut point detection algorithm based on k-hop network,and the simulation verifies that the algorithm has an excellent global cut point detection rate.Then,a local fault-tolerant control algorithm based on k-hop network is proposed,and simulation experiments are performed.The algorithm is compared with the local block movement control algorithm and the global movement control algorithm,and it is verified that the algorithm is in the average adjustment time and cut point.Eliminate the advantages of success rate,average offset distance and node offset ratio.The topology movement control algorithm proposed in this subject has a good reference significance for fault-tolerant network topology control.
