Node localization in wireless sensor network based on vectors and particle swarm optimization
基于矢量和粒子群优化的传感器网络节点定位

An integrated algorithm based on DV-Hop was designed. A Location Correction Vector(LCV)was constructed by the differences between estimated distances and range measurements. Nodes were clustered when the anchors were the heads of clusters, object function expressing total distances error was constructed in a cluster, Particle Swarm Optimization (PSO) was used to solve the minimization problem, and then correction steps of all member nodes were obtained. The value of location correction equaled the product o...
