摘　　要：针对大量节点正态分布的无线传感器网络,为了提高网络的寿命,提出了一种移动sink的高效路径规划方案。首先由节点的分布规律将网络划分为多个子区域,然后在此基础上以最大化网络寿命为目标找到sink的最佳转折点,最后得到一条最优路径。通过NS-2中大量的仿真实验结果表明,与已有的类似方案相比,该方案可以有效均衡网络能耗,延长网络的生命周期,同时取得较好的网络性能。In wireless sensor networks with a large number of normally distributed nodes,in order to improve the network lifetime,an efficient path planning scheme of a mobile sink was proposed in this paper.Firstly,the network is divided into several subregions by the distribution of nodes.Then,the best turning point of sink on this basis is found in order to maximize the network life time.Finally,an optimal path is got.Lots of simulation results under NS-2show that compared with existing similar schemes,this scheme can effectively balance the network energy consumption,prolong the network lifetime and achieve better network performance.
