无线传感器网络中一种具有稳定链路的鲁棒可调拓扑算法

该文针对传感器网络中无线链路的不稳定性问题,基于r邻居图模型提出一种具有稳定链路的鲁棒可调拓扑控制算法RAWSL (Robust Adjustable with Steady Links)。算法以接收信号强度阈值作为链路判断条件,有效地避免了网络中不稳定链路存在的可能性,并能够通过调整参数r取值满足不同网络的需求。实验结果表明,RAWSL算法不仅能够确保全网络的连通,还具有鲁棒性高和时延较低的特点。

A Robust Adjustable Topology Algorithm with Steady Links in Wireless Sensor Network

In order to solve the problem of wireless link instability in sensor network, based on the r-neighborhood graph model, this paper puts forward a robust adjustable topology control algorithm with steady links, named RAWSL. RAWSL algorithm sets the receive signal strength threshold as the limit of topology, which to avoided effectively the instability links, and by adjusting the value of parameters r to fit a variety of network robustness requirements. The experiment results show that, RAWSL algorithm not only ensures the entire connectivity, it also has higher robustness and lower delay characteristics.
