数据收集单元和移动Sink辅助下的信息上传方法
|
摘要
为提升无线传感网数据收集能效,提出了一种基于移动Sink节点的数据上传策略。网络被划分为若干由三个数据收集单元构成的虚拟区域,并在各区域中根据节点剩余能量及其与区域中心的距离远近选出簇头。在数据收集过程中,Sink以固定的速度在遍历点间移动,而仅有簇头节点向其上传数据,从而有效降低了能耗。
To enhance energy efficiency on data gathering in Wireless Sensor Networks, a mobile Sink based data uploading strategy is proposed. The network is divided into several virtual regions consisting of three data gathering units and the cluster header of each region is selected out according to its residual energy as well as the distance to the center of the region. During data gathering process, Sink moves from one traverse point to another with a fixed speed and only the cluster headers upload data to the mobile Sink that effectively reduces energy consumption.
