摘要
针对无线传感器网络(WSN)节点的优化部署问题,为改善因静态节点优化部署产生的诸多问题,使WSN未知节点动态部署的精度得到进一步提高,提出一种改进的粒子群优化动态节点部署算法。将区域分成大小相等的子区域,引入拟态物理学优化算法,根据子区域及其相邻区域的节点数目对其赋予一定的加权值,简单快速寻找到移动节点的坐标。实验结果表明,该算法的种群多样性更优,部署精度更高,将网络对目标区域的覆盖质量提高到了0.981。
To solve the problem of optimal deployment of wireless sensor networks(WSN)nodes and to solve many problems caused by the optimized deployment of static nodes.To further improve the accuracy of dynamic deployment of wireless sensor networks unknown nodes,an improved particle swarm optimization dynamically deploying nodes algorithm was proposed.The region was divided into equal sub-regions,physicomimetics optimization algorithm was combined,and a certain weighted value was assigned according to the number of nodes in the sub-regions and its adjacent regions.The coordinates of the mobile node were found simply and quickly.Experimental results show that the proposed algorithm has better population diversity and higher positioning accuracy,the coverage quality of the target area is increased to 0.981.
