摘要:

在无线传感器网络乃至无线网络邻域中,拓扑控制一直是研究热点之一,是无线传感器网络中一种重要的能量节省技术。当前已有很多能量高效的拓扑控制算法,它们试图寻求一个合适的节点发射功率或者一个良好的网络拓扑结构,实际应用中两者往往都需要考虑。提出一种新的拓扑控制方法——HFLTC,该方法基于模糊控制和链路质量评估模型优化进行功率控制,并引入XTC算法思想成链。仿真结果表明,这种把拓扑结构和功率控制结合考虑的方法,更节省网络的平均能耗,提高了整个网络的生命周期。

Abstract:

In wireless sensor networks and even wireless networks, topology control is a research hotspot. Nowadays, many topology control algorithms claim to be energy efficient, which try to find either appropriate transmit power or good network topology. However, in practice, the two aspects both should be considered. We propose a novel topology control method called hybrid fuzzy-logic topology control (HFLTC) which introduces the idea of XTC to build links. It is based on the fuzzy control and an optimized link quality evaluation model to achieve power control. Simulation results show that the method that combines topology and power control together can save more average energy consumption of networks and extend the entire network life cycle.
