Research on optimization method of formation air defense communication network based on timeliness assessment

Communication network optimization including assessment indexes and optimization method, the accuracy of the evaluation index and calculation efficiency will directly affect the optimization results of communication network, this paper in the process of tf in the empty communication networking, communications relay time delay too long to link the negative impact of the information transmission timeliness, the paper constructs the evaluation index of average shortest path length of the communication network timeliness model, and combined with the improved genetic algorithm, is proposed based on the timeliness evaluation fleet air communications network optimization method, realize the path length between the network nodes (hop) and network optimization. The simulation results show that, compared with the traditional Dijkstra algorithm, the improved method based on the shortest path genetic algorithm has the advantages of fast convergence speed and low convergence time due to the network size change, and the practical application effect is remarkable.
