利用分簇技术可以有效延长无线传感器网络的生存时间.当簇头以多跳通信的方式将数据传输至基站时,靠近基站的簇头由于转发大量数据而负载过重,可能过早耗尽能量而失效;丽当采用单跳方式时,远离基站的簇头因传送数据能耗太高而很快死亡.为了均衡簇头的能耗,提出一种基于簇的分时使用单跳和多跳的混合路由算法.仿真实验表明,算法能均衡簇头的能量消耗,有效延长网络的生存时间.

Clustering provides an effective way for prolonging the lifetime of a wireless sensor network.When cluster heads transmit their data to the base station via multi-hop communication,the cluster heads closer to the base station are burdened with heavy relay traffic and tend to die early.Alternatively,if all cluster heads transmit data packets directly to the base station,the cluster heads further from the base station will die much more quickly than those closer to the base station.To balance the cluster heads energy dissipation,the paper proposes a hybrid cluster -based routing algorithm where the cluster heads can transmit data to the base station in either single-hop or multi -hop mode.Simulation results show that the routing algorithm balances the energy consumption among cluster heads and achieves an effectively improvement on the network lifetime.
