面向无线传感器网络节点定位的移动锚节点路径规划

Mobile Anchor Path Planning for Wireless Sensor Networks Localization

针对无线传感器网络定位的需求,对移动节点的路径进行了分析与规划。首先设计了移动锚节点与传感器节点间的通信过程,使锚节点获得足够的局部邻居信息,作为后续动态选择目标子区域的基础。然后设计了一种动态、静态轨迹相结合的移动路径,在保证定位率的同时,可以有效避开网络中的空白区域。仿真结果表明:在不同的节点分布下,本工作的算法在定位率和路径长度等方面有良好的表现。

For the problem of node localization,this paper makes an analysis and plan for the path of the mobile anchor.The mobile anchor communicates with the sensor nodes in the network so that it can get the knowledge of local neighbor information,which is a basic for selecting target sub-region dynamically.A path combining dynamic and static trajectory is designed,which can effectively avoid the holes of the deployment region while ensuring the localization ratio.Simulation results show that the algorithm has good performance on localization ratio and path length under different node distributions.
