摘　　要：传感器节点将收集到的数据传输到簇头,簇头将数据包聚合后再发送到基站。远离基站的簇头,因发送数据的能耗太高而提早死亡。为此,在研究了传感器网络中节点的能耗后,提出一种非均匀的节点部署算法,得出了一个部署传感器节点的密度函数,在远离基站的区域部署较多的节点。仿真实验表明,非均匀的节点部署算法能有效延长网络的生命周期。Sensor nodes transmit their collect data to designated cluster heads. Cluster heads aggregate the data packets and send them to the base station. Cluster heads further from the base station will die much more quickly than those closer to the base station. To address the problem, we propose a non-uniform deployment algorithm through investigating energy consumption in sensor network. The algorithm presents a density function to deploy sensor nodes and enables that areas further from the base station have more nodes. Simulation results show that our proposed algorithm is effective for prolonging the network lifetime.
