一种基于助理簇头的持久化分簇路由协议

A Persistant Cluster-based Routing Protocol Based on Assistant Cluster Heads

在无线传感器网络分簇路由协议中,簇头负责簇内成员的管理,数据的收集和融合,以及数据的转发,造成簇头的能量消耗过甚,从而使网络浪费有效的能量来频繁的分簇重组,最终减小网络的生命周期.针对此问题,提出了一种基于助理簇头的持久化路由协议,通过添加助理簇头,代替簇头行使多跳路由选择,及其数据转发任务,使簇头有更多剩余能量来维持簇的管理,从而延长簇的生命周期,减少网络重组频率,进而延长整个网络的生命周期.实验仿真结果表明,改进的协议显著的提高了节点能量利用率,并延长了网络的生命周期.

In clustering routing protocol of wireless sensor networks, cluster heads are responsible for the management of the mem- bers, data collection and integration, and answer for data forwarding. The energy of the heads consumed to much lead the network to frequently cluster and reconstruct. Finally it will shorten the network life time. In the paper we puts forward based on the persistent cluster head of assistant routing protocols, by adding assistant cluster heads, instead of cluster heads, are charge of multi-hop routing and data forwarding task, so the cluster heads have more energy to maintain the current cluster management, prolong the life of the clusters, and reduce restructuring frequently. Finally extending the life of the whole network. The simulation experiment results show that the improved protocol can significantly increases the energy utilization ratio, and prolongs the network＇s lifetime.
