节点能量有限是无线传感器网络通信协议设计中的一个重要瓶颈，因此，在无线传感器网络中，考虑网络节点能量的高效利用具有十分重要的理论和实际意义。因而，提出一种基于权值机制的非均匀分簇路由算法，该算法采用权值的局部竞选簇首策略，簇首根据距离信息构建大小不均的多个簇，簇成员节点以链式结构向簇首传送数据，最后簇首采用多跳的方式向基站传送数据。实验仿真结果表明，提出的新算法能有效地降低和均衡网络节点能耗，改善“热区”问题，显著地延长网络生命周期。

Note energy limitation is the crucial point in communication protocols of wireless sensor networks. It’s important to improve the nodes energy efficiency. Proposed an uneven Cluster routing algorithm( UCPA) based on Weight. The new local cluster head is selected according to the weight. And the new local head constructs its cluster with its own size according to the distance information. The data is transferred in chains from members to the head, and in dynamic multi-hops from cluster-heads to base station. Simulation results show that this new algorithm effectively reduces network energy consumption, and can balance the energy consumption of network and better reduce the impacts of the "hot spots" and the network lifetime is prolonged obviously.
