Research on the Routing Method of Swarm Network Based on Moth Search Link Distance and Residual Energy Weights

Routing method is a key technology for swarm communication. In order to reduce the node energy consumption in large-scale swarm communication, a routing method based on moth search link distance and residual energy is proposed. First, the swarm network is divided into sub-cluster networks by filtering of cluster head nodes. The node with more residual energy is used as cluster head to forward data signals from other nodes. The link between cluster head and edge nodes is established by relaying the signals from the nodes. The routing function of the link is established by calculating the distance and residual energy weight of the nodes. During cluster head broadcast communication, a modified moth-based search algorithm is applied to solve the combined weights of the routes. The optimal solution of the function constitutes the best route within the subcluster. Simulation results show that the proposed method meets the communication requirements, while the performance of the proposed method is higher than other mainstream algorithms by comparing the magnitude of three metrics: network coverage, residual energy and BER. The proposed routing method reduces the energy consumption of multi-node cluster network communication. The method achieves routing for large-scale cluster communication.
