摘要
在异构传感器网络中,超级节点有着重要的意义.针对异构传感器网络中超级节点能量消耗过快的问题,提出了一种新的分簇路由协议(MCC).通过在建簇阶段采用簇首移动控制策略来使簇内负载更加均衡;在簇间数据传输时引入了节点协作转发机制,提高了分簇协议的数据传输性能.通过NS2仿真验证,结果表明,MCC协议不仅降低了簇首能耗,而且使网络能耗更加均匀,延长了网络寿命.
A new cluster-based routing protocol was proposed to solve the problem that energy of super nodes decrease fast in heterogeneous sensor network.Firstly cluster head movement control strategy makes the network load more balanced.Then node forward collaboration mechanism enhances the clustering transmission performance.The protocl was verified by NS2 simulator.Simulation results demonstrate that this protocol not only can decrease the energy consumption,but also make the network energe consumption more balanced and prolong the network lifetime.
