摘　　要：针对同构无线传感器网络的能源瓶颈问题提出一种能源有效的自适应路由协议,该协议在分布式动态分簇的基础上提出一种班车算法对数据进行逐层汇聚,以减少网络中流动数据包的数量,同时分担簇头节点的计算量。Tossim仿真试验表明该协议能够显著地减少节点的能量开销,提高网络的适应性,有效地延长网络的生命周期。As a new technology for message acquiring and processing, wireless sensor networks have a huge foreground in military field, environment detecting, space exploring and so on. As to resolve the energy problem of homogeneous wireless sensor networks, a new energy efficient routing protocol named EERP is proposed and also the simulation results with Tossim is shown in this thesis. The results show that by aggregating the data step by step EERP can save the node＇ s energy remarkably and prolong the lifetime of the network effectively.
