摘　　要：基于能量信息的目标定位模型,提出了一种能量有效的本地节点选择方案,通过合理地选择处于工作状态的传感器节点以减少网络的能量消耗。该方案中,节点根据相邻时刻接收到的目标信号能量变化独立决定其工作状态,减少了与相邻节点及中心节点的信息交换。仿真结果表明:应用该文提出的节点选择方法有效减少了网络的能量消耗,且能够准确地对目标进行定位与跟踪。An energy-efficient local node selection strategy is presented for target locating and tracking based on the received energy information that saves the network energy through selecting the reasonable sensor nodes. In the proposed scheme, each node decides its working status independently based on energy variation of the received target signal, which greatly reduces the information exchanges with the neighbor nodes and center nodes. The locating and tracking performance using the proposed node selection scheme is evaluated by computer simulations. The results show that accurate locating and tracking with very low energy consumption is achieved.
