为了进一步提升Q-Leach协议的性能,均衡无线传感器网络能量消耗,文中提出了一种改进型路由协议UMQ-Leach。该路由协议合理利用了Q-Leach协议的子区域划分规则,借此简化了簇间多跳通信机制；为了进一步均衡网络能耗,引入了非均匀分簇策略,并设计了随节点能量变化的自适应竞争半径,通过自适应竞争半径改善了协议性能。仿真结果表明,与Leach、Q-Leach协议相比,UMQ-Leach具有更好的网络能耗均衡性,进一步延长了网络的生命周期。此外,仿真结果同样说明UMQ-Leach协议中最大竞争半径的选取能够影响协议性能。

In order to enhance the performance of the Q-Leach routing protocol and balance the energy consumption of the wireless sensor network,propose a modified routing protocol called UMQ-Leach. The proposed routing protocol takes use of the sub-region partitioning rules of Q-Leach to simplify the multiple hops communication mechanism. Besides,in order to balance network energy consumption fur-ther,the unequal clustering strategy is introduced and adaptive competition radius changing with node energy is also designed to further improve the protocol performance. The simulation results show that the UMQ-Leach has better performance compared with Leach and Q-Leach in prolonging the life cycle as well as balancing the network energy consumption. What' s more,the results also show that the val-ue of maximum competition radius can impact the performance of UMQ-Leach.
