摘　　要：ZigBee网络通常通过电池提供能源,某些节点的电池能量消耗较大,会导致网络分割和节点过早死亡,影响整个网络的生存。为了实现ZigBee网络的能量优化,延长网络生存时间,提出一种基于网络编码感知的能量均衡的ZigBee路由策略NCEBR(Network Coding-aware based Energy-Balanced Routing)。该策略能够选择具有最小总能耗和最小剩余能量的路径传输分组以均衡网络节点能量消耗,同时通过网络编码降低节点能耗。仿真结果表明,与传统的ZigBee路由协议相比,NCEBR策略能够减少死亡节点数,均衡网络能量消耗,延长网络生存时间。In the ZigBee networks which is generally supplied electricity by battery,the high energy consumption of some nodes will cause the network partitioning and nodes died too early,which affects the existence of the whole network. To achieve energy optimization and prolong the survival time of ZigBee networks,a Network Coding-aware based Energy-Balanced Routing protocol （ NCEBR） of ZigBee is proposed. The protocol can balance energy consumption among nodes in a network by routing packets in a route with the least total en-ergy consumption and the least residual energy,and use network coding to reduce the energy consumption of nodes. Simulation results in-dicate that NCEBR can decrease the number of death nodes,balance the network energy consumption and prolong the network lifetime compared with the traditional ZigBee routing protocol.
