传感器网络由于资源受限,定位算法需要综合考虑定位精度,网络构建成本,通信、计算开销等多方面因素。本文采用移动锚节点并结合Bounding Box算法特点,提出一种基于移动锚节点的无线传感器网络定位算法(MBB)。算法原理简单,传感器节点无须任何附加硬件或附加数据通信,通信、计算复杂度较低。仿真实验表明该算法具有很高的定位精度,即使节点的实际通信半径小于理论通信半径,定位精度仍可保持在较高等级,算法定位精度与网络连通度无关。
Due to limited resources, sensor networks need to consider various factors such as positioning accuracy, network construction cost, communication, computing overhead and so on. In this paper, a mobile anchor node based Wireless Sensor Network Location Algorithm (MBB) is proposed based on the characteristics of Bounding Box algorithm. The principle of the algorithm is simple, sensor nodes do not need any additional hardware or additional data communication, communication, low computational complexity. Simulation results show that the proposed algorithm has high positioning accuracy. Even if the actual communication radius of the node is less than the theoretical communication radius, the positioning accuracy can be maintained at a high level, and the positioning accuracy of the algorithm has nothing to do with the network connectivity.
