摘　　要：设计了两种能量均衡策略,提出基于微簇策略的能量均衡路由协议.该协议将相邻两节点联合成微簇,微簇内的节点基于剩余能量进行负载调配,以实现局部的能量均衡;对节点间的梯度值进行模糊分级,并将模糊等级选择策略与质量评价函数相结合进行下一跳节点选择,以实现全局的能量均衡.仿真表明该协议能更均衡地利用有限能量,降低节点的平均能耗和传输时延,延长无线传感器网络的寿命.Two energy equilibrium strategies routing protocol （MCEE） was proposed and i two neighbor nodes, and the cooperation in it were designed. Micro-cluster based energy equilibrium mplemented. In MCEE, micro-cluster was built between balanced the energy consumption locally. A fuzzy gradi- ent classification based next-hop strategy was designed to equilibrate the energy consumption as a whole. The simulation results showed that limited energy could be effectively used through MCEE. Namely, the average energy consumption and transmission delay could be lighted and the lifetime of wireless sensor network increased.
