一种高节能多跳分层路由协议

High Energy-efficient Multi-hop Hierarchical Routing Protocol

针对无线传感器网络节点存在电池能量有限和通信过程中能量消耗大等缺点,为最大限度地延长无线传感器网络的寿命,解决节点能耗分布不均匀的问题,提出了一种高节能多跳分层路由HE-EMHR协议。协议分别根据节点的能源决策和新的权函数来选择簇头和簇头的下一跳,并引进一种新因子确定候选节点。试验证明了该协议的有效性,表明此协议能保证网络具有更强的生存能力和更长的生命周期。

Aiming at the features of limited battery energy in nodes of wireless sensor network （WSN） and large amount of energy consumption in communication process, in order to maximize the lifetime of the network, and solve the issue of uneven distribution of the node energy consumption, the high energy-efficient multi-hop hierarchical routing （HE-EMHR） protocol is proposed for reducing energy consumption. The pro- tocol selects the cluster head according to the energy strategy and the next hop based on the weight function; and introduces a new factor for se lecting candidate node. The experiment proves the effectiveness of this protocol and indicates that the protocol is able to guarantee the network offering stronger survival time and longer life period.
