Location algorithm use mobile beacon in wireless sensor networks
一种单移动锚节点的无线传感器网络定位算法

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.
