一种单移动锚节点的无线传感器网络定位算法

研究了无线传感器网络的节点定位算法，提出了一种利用一个移动锚节点来实现定位的新算法。该算法利用一个移动锚节点，按照规划好的路径遍历整个网络，当移动锚节点移动到未知节点的通信半径以内，未知节点就可以接收锚节点的位置信息。当未知节点接收到三个以上的处于其通信半径上的位置信息，就可以计算出未知节点的坐标。最后，通过仿真研究了该算法的特性，仿真结果表明该定位方法在定位误差、能耗等方面均表现出良好的性能。

Location algorithm use mobile beacon in wireless sensor networks

This paper investigated a location algorithm in wireless sensor networks, and proposed a new location algorithm use a mobile beacon. The main idea of the algorithm was to use a mobile beacon to traverse the network follow the planned path.When the mobile beacon moved into the communication scope of the unknow node, the location of the mobile beacon received by the unknow node.The unknown node calculated its position after it received more than 3 position in its communication radius. Simulations were carried out to study the characteristic of the algorithm.The simulation results demonstrate that the location algorithm performs well on the aspects of location error and energy consumption.
