| 摘 要： | 为延长无线传感网的生命期，提出了一种能量空洞缓解方法。网络被划分为若干虚拟栅格，以便于多跳传输。树形结构的数据上传路径则由各个簇头和移动Sink构成。此外，为缓解能量空洞的出现，Sink的移动轨迹被设计为可控的，从而有效均衡了能耗。仿真结果表明，该方法在多跳传感网络的节能方面表现较为良好。

| Abstract: | To prolong network lifetime in wireless sensor networks, a type of energy hole mitigation strategy is proposed in this paper. The network is divided into several virtual girds for multi-hop transmission and a tree-based data uploading path can be established with the help of the cluster headers as well as the mobile Sink. Moreover, to mitigate the “energy hole problem”, moving path of the mobile Sink is controllable that effectively balances energy consumption. Simulation results show that, this method performs well on energy saving in multi-hop transmission sensor networks. |
