摘要:

设计并实现了一种面向能耗均衡的传感网单移动sink数据收集方法.利用传感网完全覆盖模型确定了sink在网内各遍历点的具体坐标,并在此基础上,构建了其定长移动数据收集轨迹.实验结果表明,该方法的能耗均衡性优于虚拟节点策略、基于效用的贪婪启发式交会点找寻等典型的移动sink数据收集方法.

Abstract:

A type of data gathering method based on one mobile sink for balanced energy consumption in sensor networks (DGBEC) was proposed. Coordinates of each traverse point was calculated by sensing coverage model, and the path with fixed length for mobile sink was also built. Simulations show that DGBEC performs very well in energy consumption balance than virtual nodes priority (VNP) and rendezvous points finding with a utility-based greedy heuristic (RP-UG) methods.

Key words: wireless sensor networks, mobile sink, data gathering, energy consumption balance
