AbstractThe clustering algorithm for Wireless Sensor Network(WSN) is optimized by Particle Swarm Optimization(PSO) algorithm. The master
cluster-head and the vice cluster-head are considered according to the information of both normal nodes and the cluster-heads. The master cluster-
head is used for date collecting and date integration. The integrated dates are sent to the vice one. The vice cluster-head charges for the
communication with base station. This algorithm can balance the energy consumption, so it can extend the network lifetime effectively. Simulation
results show the lifetime of the algorithm is extended for 50% contrast with LEACH.
