摘　　要：针对无线传感器网络中因空洞引起路由效率降低的问题,该文提出了基于3维胞元空间的能量高效性多通道协助路由算法(3D-EEMCR)。该算法根据能量损耗模型,权衡考虑节点的剩余能量和位置信息来选举胞父节点,从而平衡网络能耗;另外,算法采用主通道和辅助通道相互协助的周边路由模式完成空洞区域的路由。仿真结果表明,3D-EEMCR相比3D-GPR(Grid Position-based Routing)和3D-CSR(Cell Space Routing)能够有效提高消息包的发送率,降低网络的平均能耗,延长网络的生存周期。To deal with the degradation of wireless sensor network routing efficiency caused by voids, Energy Efficiency Multi-channel Coordination Routing algorithm based on 3D cell space （3D-EEMCR） is presented in this paper. According to the energy consumption model, the algorithm balances residuM energy and location information of the nodes to select the cell leader node, so as to balance the energy consumption of network. In addition, the algorithm adopts perimeter routing mode which uses the mutuM assistance of the main channel and the assistant channels to route around void areas. The simulation results show that 3D-EEMCR effectively improves the message packet delivery rate, reduces the average energy consumption of the network, and extends the network lifetime in comparison with 3D-GPR （Grid Position-based Routing） and 3D-CSR （Cell Space Routing）.
