【摘要】：针对无线传感器网络(WSN)中目标追踪的准确性低、网络能耗过高和网络生命周期短等问题,提出基于动态分簇的移动目标追踪技术。首先,构建了双层环状动态分簇的拓扑模型(TRDC),并提出了动态分簇的更新算法;其次,在质心定位算法基础上,考虑到节点的能量,提出了基于功率级别的质心定位(CLPL)算法;最后,为了进一步减小网络的能耗,改进CLPL算法,提出了随机性定位算法。在仿真实验中,与静态簇相比,网络周期延长了22.73%;与非环状簇相比,丢失率降低了40.79%;而追踪准确性与基于接受信号强度值(RSSI)算法相差不大。所提的追踪技术能够有效保证追踪准确度,同时降低网络能耗,减小目标丢失率。
[Abstract]:Aiming at the problems of low accuracy of target tracking, high network energy consumption and short network life cycle in wireless sensor networks (WSNs), a moving target tracking technique based on dynamic clustering is proposed. Firstly, the topology model of double-layer ring dynamic clustering is constructed, and the updating algorithm of dynamic clustering is proposed. Secondly, based on the centroid location algorithm and considering the energy of nodes, a new CLPL-based centroid location algorithm is proposed. Finally, in order to further reduce the energy consumption of the network and improve the CLPL algorithm, a random location algorithm is proposed. In the simulation experiment, compared with the static cluster, the network cycle is prolonged by 22.73, the loss rate is reduced by 40.79 compared with the non-ring cluster, and the tracking accuracy is not different from the RSSI algorithm based on the received signal strength. The proposed tracking technique can effectively guarantee the tracking accuracy, reduce the network energy consumption and reduce the target loss rate.
