摘要
路由协议是无线传感器网络的重要组成之一,路由算法在路由协议中又起着重要的作用。为降低能耗和提高网络生命周期,针对典型的LEACH路由算法,提出基于节点自适应调度的LEACH算法。该算法采用考虑网络的覆盖和连通性的方法,利用连通覆盖集来实现节点自适应调度。采用NS2仿真做时间能耗与时间存活节点两方面的实验,结果表明该方法能够降低能耗,有效延长网络的生存时间。
Routing protocol is an important part of wireless sensor networks, the routing algorithm plays a crucial role in routing protocols. In order to reduce energy consumption and prolong the network lifetime, LEACH algorithm based on node self-schedu- ling is proposed. The algorithm considers the network connectivity and coverage, determines the connected cover set to realize node self-scheduling. The NS2 simulation includes time-energy consumption and time-numbers of living nodes. The results show that the algorithm can reduce energy costs and prolong the network lifetime.
