摘　　要：利用移动代理将计算移动到数据的特性,设计了一种无线传感器网络目标定位算法.该算法让所有感应到目标的节点竞争移动代理,然后让移动代理对目标进行跟踪定位,竞争移动代理的规则由节点与目标之间的距离及其剩余能量值而定.实验证明,本算法不但能延长网络的寿命,还能提高目标定位的精确性.Based on the virtues of mobile agent in the target localization algorithm,a target localization algorithm in wireless sensor networks was proposed.All the sensor nodes that know target compete to get the mobile agent in order to track the location of targets.Competition rules are defined by the remaining value of the energy and the distance between the nodes and the target.Simulation results showed that this algorithm not only extend the life span of the network,but also take into account the accuracy of targeting.
