摘　　要：无线传感网络在节点能耗大差异的情况下,其网络覆盖存在节点部署效果差、覆盖率低等问题,因此,设计一种新的大差异无线传感网络节点最佳覆盖部署算法。通过三角点阵排列法,以节点能耗大差异角度,确定最少部署节点数量,并且初步部署节点,引入离子键导向的粒子群优化覆盖算法,在粒子群算法中增加离子键导向,获取节点最佳位置,从而获取网络节点最佳部署,实现网络节点最佳覆盖部署算法设计。仿真结果表明,所提方法对传感网络大差异节点部署效果较好,节点分布均匀,重复覆盖较少,节点利用率为95%,覆盖率达到99.0%以上,该方法有效优化了网络节点部署效果,达到了最佳覆盖。Wireless sensor networks have the problems of poor node deployment effect and low coverage probability in the case of large differences in node energy consumption.Therefore,a new optimal node coverage deployment algorithm for wireless sensor networks with large differences is designed.The minimum number of deployed nodes is determined from the angle of large difference in node energy consumption through the triangular lattice arrangement method,and the nodes are initially deployed.The ion bond oriented particle swarm optimization coverage algorithm is introduced,and the ion bond guidance is added to the particle swarm optimization algorithm to obtain the optimal location of nodes,so as to obtain the optimal deployment of network nodes,therefore,the design of the optimal cover-age deployment algorithm of network nodes is realized.The simulation results show that the proposed method has a good effect on the deployment of nodes with large differences in the sensor network.The nodes are evenly distributed,the overlapping coverage is low,the node utilization rate is 95%,and the coverage probability is above 99.0%.The proposed method effectively optimizes the deployment effect of network nodes and achieves the best coverage.
