摘要
The routing protocol of WSN based on clustering hierarchy has been one of the important research topics. An improved strategy based on LEACH (Low Energy Adaptive Clustering Hierarchy) is proposed in this paper, which uses the PSO algorithm to optimize clustering process by considering the energy, the communication costs, the load balance and other factors to determine the cluster-head node. The simulation results show that the improved algorithm can solve the problems in LEACH, such as uneven clustering, uneven load of the cluster-head node and other disadvantages, and it can prolong the WSN lifetime.
