传感器节点能量消耗不均衡，是影响无线传感器/执行器网络寿命的关键问题之一。文章提出基于节点分区的能耗均衡路由协议（ERPN P ），该协议在保证网络连通性的基础上，通过簇内传感器节点分区、传感器节点到执行器节点路由选择、执行器节点到sink节点路由选择等步骤，使传感器节点的发射功率尽可能的小，同时下一跳节点距离执行器节点越来越近，即选择较多节点较小发射功率的传输路径，避免选择较少节点较大发射功率的传输路径，利用较多节点分担传输能量，均衡节点能耗，提高网络寿命。仿真实验表明，相比于传统协议，ERPN P协议能够显著延长网络生存时间。

Unbalanced energy consumption of sensor nodes is one of the key issues affecting wireless sensor and actor network(WSAN) lifetime .To solve this problem ,an energy balancing routing proto-col based on node partition(ERPNP) is proposed .The protocol guarantees the network connectivity and transmits data by sensor nodes partition within the cluster ,sensor node to actor node routing and actor node to sink node routing .The protocol allows sensor nodes transmission power to be as small as possible ,and at the same time ,the next hop node is getting closer to the actor node ,which means that the protocol selects transmission path of more nodes and smaller transmission power than others . By using more nodes to share the energy ,the protocol can balance the energy consumption of nodes and improve the network lifetime .Simulation results show that compared with traditional protocols , ERPNP protocol extends network lifetime significantly .
