摘要 在研究现有无线传感器定位算法基础上提出了主动分布式传感器节点定位策略(ADLA),该算法借鉴集中式凸规划算法的思路,提出了一种方法简单的分布式位置估计方法。该方法计算简单,内存需求少且通信开销低。经过试验证明,该算法的定位精度在锚节点连接度为18个的情况下,可以达到0.6倍节点通信距离的精度,完全可以满足无线传感器网络一般的定位需求。 The active distributed algorithm for sensor node localization is proposed based on convex programming approach. The algorithm require only simply computation, less memory and very low communication overhead. Simulation shows that the average position error reach 0,6 time of the node＇s radio range when the anchor, nodes is 18. The result can meet the general localization requirement of wireless sensor networks.
