To maximize the network coverage and extend the life of the network,this paper proposed a wireless sensor networks(WSN) coverage optimal strategy based on standard particle swarm optimization(PSO).By using clustering and collision theory,the particles which fell into the best part area could be chosen rapidly.The strategy also avoided a phenomenon of premature which often occured when using the method of standard PSO,and improved the stability of the algorithm.The paper analyzed the influence about cluster number and threshold value on the coverage performance through the simulation experiment.Experimental results indicate that the collision and clustering-based PSO strategy acts effectively in coverage optimization.
