| 摘 要： | DV-Hop算法是一种经典的距离无关的无线传感器网络节点定位算法.详细分析了DV-Hop算法的定位过程,针对其局限性提出一种改进的DV-Hop算法.该改进算法在传统DV-Hop算法的第一阶段采用分簇策略以减小通信开销和分组冲突概率,并且用拟牛顿优化算法代替传统的最小二乘法计算节点位置,最后用Matlab7.0进行仿真....

| Abstract: | DV-Hop algorithm is a classical range-free localization algorithm used for node locating of wireless sensor network.After analyzing the localization principle and limitation of DV-Hop algorithm,the authors proposed an improved DV-Hop algorithm.The new algorithm used cluster strategy to reduce communication cost and grouping conflict probability in the first stage,and quasi-Newton optimization method was used instead of the least-square method to estimate the position of nodes.Simulation was made by using Ma... |
