摘要:

针对无线传感器网络(WSN)中的节点定位精度不足的问题,提出一种基于优化粒子算法与膜计算(improved particle swarm optimization by membrane computing,IPSO-MC)的融合算法。采用Kent映射初始化种群和引入领域粒子提高粒子群全局优化能力,通过权重因子和非线性极值扰动提高粒子群的局部优化能力,利用Levy飞行机制优化个体位置,借助膜计算的进化规则最终获得粒子群算法的最优解。仿真实验表明,与鸡群算法、改进的粒子群算法和膜计算的定位算法相比,本文算法在参考节点比例指标对比中分别提高3.24%、5.12%和8.15%、在节点个数指标对比中分别提高2.26%、7.82%和9.81%以及在通信半径指标对比中分别提高2.15%、5.5%和7.5%,说明该算法在节点定位方面具有良好的效果。

Abstract:

To solve the problem of insufficient node positioning accuracy in wireless sensor networks,an algorithm based on improved particle swarm optimization by membrane computing (IPSO-MC) was proposed.Kent mapping was used to initialize the population and domain particles were introduced to improve the global optimization of the particle swarm.The weight factor and nonlinear extreme value perturbation were used to improve the local optimization ability of the particle swarm,and the Levy flight mechanism was used to optimize the individual position.Finally,the optimal solution of the particle swarm algorithm was obtained by the evolutionary rules of the membrane computing.Simulation experiments show that compared with the chicken flock algorithm,the improved particle swarm algorithm and the membrane computing,the proposed algorithm improves 3.24%,5.12% and 8.15% in the comparison of reference node ratio indicators,and the increase in the number of nodes indicators by 2.26%,7.82% and 9.81%,and the comparison of communication radius indicators increased by 2.15%,5.5% and 7.5%,respectively.This indicates that the algorithm has a good effect in node localization.
