摘　　要：在无线传感器网络中,移动Sink通过遍历驻留点进行数据收集能够有效防止热点或能量空洞问题.为了提高基于移动Sink的无线传感网的数据收集效率,提出了一种基于移动Sink的无线传感器网络能量高效的驻留点路由算法.通过对网络生命周期最大化问题进行建模,利用蚁群优化的思想对最优的驻留点集合和移动Sink遍历路径进行求解,实现了最大限度地延长网络寿命的同时最小化从传感器节点收集数据的延迟.实验结果表明:所提出的算法与已有算法相比,在延长网络的生命周期、提高交付率和减少端到端时延等方面具有更好的性能.In Wireless Sensor Networks,Mobile Sink can effectively prevent hot spots or energy holes by traversing the dwell points for data collection.In order to improve the efficiency of data collection in Wireless Sensor Networks,an energy-efficient dwell point routing algorithm for Wireless Sensor Networks based on Mobile Sink is proposed.By modeling the network life cycle maximization problem,the ant colony optimization is applied to solve the optimal set of dwell points and the Mobile Sink traversal path,which can maximize the network life and minimize the delay of collecting data from sensor nodes.Experimental results show that the proposed algorithm has better performance than existing algorithms in extending the network life cycle,improving the delivery rate and reducing end-to-end delay.
