一种新的基于能量消耗速率模型的分簇路由协议

摘要

Using energy-efficient routing protocol, wireless sensor networks can save much energy, but there are still the problems of rapid and uneven energy consumption. LEACH,called low energy adaptive clustering hierarchy routing protocol, is one of the most classical routing protocols, which ignores both the rate of energy dissipation and the distance between normal node and sink node during the election of cluster header. Focusing on these limitations, a novel clustering routing protocol was proposed. Experimental results show that the new protocol makes the consumption of energy more balanced,decreases energy dissipation and extends the lifetime of sensor network.%无线传感器网络中通常采用分簇路由协议采减少能耗,但仍然存在节点能量消耗快且不均匀的问题.鉴于经典的低功耗自适应集簇分层型协议LEACH的簇头选举过程中,没有考虑节点能量消耗速率和普通节点到sink节点距离的局限性,提出了一种新的分簇路由协议.仿真实验表明,新协议能够使节点能量均匀分布,降低节点能量消耗,延长传感器网络的生存周期.
