摘　　要：目的均衡网络中节点的能量消耗,避免能量洞问题,延长网络寿命。方法在不等级环模型的最内环引入非均匀分簇思想。结果通过产生不同大小的簇,使得越靠近sink簇的簇内成员越少,有利于簇首将更多的能量用于簇间的数据转发,并通过簇首轮换,均衡簇首的能量消耗。结论该方法大大减少了最内环节点的能量消耗,延长了网络的生命周期。Aim To balance node energy consumption, avoid energy hole problem and prolong the network life. Methods The uneven cluster routing protocol is introduced in inner ring level of non-uniform ring energy level mod- el. Results Through producing clusters of different sizes, the clusters which are closer to the sink are made to in- clude less of members, and this is good for the cluster heads use more energy in the data forwarding between clusters, and through the cluster heads rotation, the energy consumption of cluster heads is balanced. Conclusion The meth- od greatly reduces the energy consumption of inner nodes, and extends the network life cycle.
