移动传感器网络中能量有效的数据融合算法

数据融合是无线传感器网络中节省能量的一个重要途径,已有的数据融合算法大多是基于结构的,但移动网络中拓扑动态变化,维护稳定的拓扑结构所需开销较大。该文提出一种适合移动传感器网络的无结构的数据融合算法EEDAARW,该算法分别使用DAA机制和随机等待机制实现时间和空间上的融合,能够平衡网络中节点的能耗,延长网络的生命周期。实验表明,EEDAARW算法使得网络生命周期比非结构化的DAARW算法延长约30%。

Energy-efficient Data Aggregation Algorithm in Mobile Sensor Network

Data aggregation is one of the most important techniques to save energy, and most existing algorithms are based on the structure. However, the topology changes continuously in mobile network, which leads to a high cost for maintaining a steady structure. This paper proposes a novel structure-free approach, Energy Efficient Data-Aware Anycast with Random Waiting(EEDAARW) protocol. It employs DAA to improve spatial convergence and RW to improve temporal convergence, so the consumption of energy is balanced an...
