Abstract

In order to improve coverage rate of wireless sensor networks（ WSNs）

reduce redundant coverage and extend the network lifetime

propose a kind of algorithm

which combines PSO with Levy flight（ LF-PSO）. The aim of optimization algorithm is to improve the coverage ratio by setting up mathematical model to describe WSNs node coverage optimization problem

use algorithms for solving mathematical models

so as to achieve the purpose of optimizing node coverage. Simulation results show that operation results of algorithm achieve expected effect and optimize the layout of the working nodes and improve coverage rate

which is an efficient and feasible node coverage algorithm for WSNs. The algorithm is quite suitable for application in WSNs node coverage optimization

which can greatly improve the coverage rate of the nodes.
