摘要
提出了一种廉价实用的自身定位算法,该方法通过校正RSSI测距技术测量的节点间点到点的距离,并优选信标节点,最后用加权质心方法进行定位。仿真结果表明:该算法比传统的RSSI定位算法拥有更好的定位性能。
Using collation of RSSI(received signal strength indicator)for range measurement between nodes and optimization of beacon node in sensor network,then localizing nodes by weight centroid algorithm.Simulation results show that this algorithm has a better performance than classical RSSI algorithm.
