摘　　要：针对无线传感器网络中节点能量受限,传统的数据收集方法需要节点将数据经过多跳转发出去,部分节点由于转发其他节点的数据而使能量快速耗尽。提出了一种在无线传感器网络中引入移动sink,并让其沿着规划好的最优路径移动从而进行数据收集的策略DCST。DCST利用蚁群算法寻找出连接所有簇头的最优路径,使移动sink沿着此路径移动并进行数据收集。仿真结果表明,相比传统的Leach算法,DCST能更好地扩张网络的循环轮数,节省整个网络的能耗。The nodes in wireless sensor networks（ WSN） energy were constrained,and the nodes need to skip through multi hop to transmit data in traditional methods of collecting data,during which some of the nodes energy rapidly depleted due to transmitting data to other nodes. We proposed a new strategy DCST that leads in mobile sink in WSN,and lets it move along the planning optimal track to collect data. DCST uses the ant colony algorithm to find out the optimal path which will connect all the cluster head and let the mobile sink move along this path to collect data. Simulation results show that DCST can prolong the network life cycle more effectively and reduce the energy consumption of the whole network compared to the traditional Leach algorithm.
