Path planning scheme based on N curve in wireless sensor networks

随着无线传感器网络的发展,节点部署在无线传感器网络中有着重要地位.为了减少定位时间和解决锚节点共线问题,提出一种N曲线路径规划方案.仿真结果表明,与现有的4种路径规划方案相比,提出的N曲线路径规划方案解决了锚节点共线问题、减少了定位时间、提高了节点定位精度.在有障碍的情况下,N曲线路径规划方案的节点定位成功率达到99%.

With the development of wireless sensor networks(WSNs),the node deployment was essential in wireless sensor networks.In order to reduce positioning time and solve the collinear beacons problem,this paper proposed a path planning scheme based on N curve.Simulation results showed that,compared with four existing path planning schemes,the proposed path planning scheme based on N reduced positioning time,solved the collinear beacons problem and improved the localization accuracy.In the case of obstacle presence,the percentage of localization success was 99%due to the path planning scheme based on N curve.
