基于模糊控制的低能耗分簇协议

能耗是影响无线传感器网络生命周期的关键,具有低能耗的无线传感器网络是业界所期望的。现有的几个网络分簇协议能在一定程度上解决和改善网络能耗问题。如LEACH协议能在一定程度上延长网络生命周期,但网络环境的可变性以及实际环境中有诸多不可估计的因素,LEACH协议就没考虑当前节点剩余能量和节点分布情况等问题。提出的基于模糊控制的低能耗分簇协议LECP-FC能较好地解决环境可变等不可估计的问题,在簇头选取的过程中着重考虑了能量、节点度、节点中心度、距离、侦听密度等因子。经过网络结构配置和仿真,其结果表明网络工作效率得到很大程度上的提高。

A low power clustering protocol based on fuzzy control

Energy consumption is the key factor affecting the network lifecycle in wireless sensor networks, so low power consumption is expected for the industry. Several existing network clustering protocols, such as LEACH protocol, can solve and reduce network energy consumption to some extent. Although they can prolong the life cycle of the network to a certain extent, there are yet many incalculable factors in the network environment and actual environment. LEACH protocol ignores the residual energy of the current node and the node distribution situation. In this regard, we present a low power clustering protocol based on fuzzy control (LECP FC) to solve the aforementioned problems. In the process of selecting cluster heads, node energy, node degree, node center, distance and listen density etc. are focused. Network configuration and simulation results show that the proposed protocol can greatly improve the work efficiency of the network.
