基于改进PSO算法的WSN覆盖优化方法

摘要

This paper proposes an improved Particle Swarm Optimization(PSO) method based on proobability of measurement model It is target at the effective coverage of the network to carry out coverage control. The sensor coverage radius and discretc grid points of the coverage performance are analyzed The effective coverage of improved PSO method reached 88.22％ by simulating. and it indicates that the method is effective.%提出基于概率测量模型的改进粒子群优化方法,以网络有效覆盖率为优化目标,通过改进粒子群算法实现无线传感器网络的覆盖控制.分析传感半径以及离散化栅格点数对覆盖性能的影响.仿真实验表明,利用改进粒子群优化方法的有效覆盖率达到88.22%,证明了该方法的有效性.
