中文摘要：

无线传感器网络的监测应用是典型的多对一网络，离Sink较近的节点需承担更多的通信负载，更容易过早地耗尽自身的能量，使网络在有大量剩余节点的情况下死亡。为此提出采用不均匀环带设计使节点能耗均衡，从而延长网络寿命的策略。利用本方法，在实际情况下不仅能确定环带半径，还延长了网络寿命。

英文摘要：

The sink will bear more residual energy. The strategy will prolong monitoring application of wireless sensor networks is typical many-to-one network. The node that is close to communication load, and is easy to deplete energy, so the network will die when there are many nodes have paper presents a new strategy that using uneven ring belt model to balance nodes energy consumption, and the network life. This method can determine the radius in any practical situation, and prolong network life.
