Abstract: This paper proposes a particle swarm optimization algorithm for Wireless Sensor Network(WSN) path optimization. In order to overcome that the diversity of the latter part of groups may decrease in the particle swarm algorithm, all aspects of particle swarm optimization are carried out analysis and improvement. It designs and increases the mutation operator. Simulation results show that this algorithm can find effective optimization of WSN routing, not only the solution quality is superior to the traditional particle swarm optimization and genetic algorithm, but also increases in the success rate.
