摘　　要：针对矩形传感器网络,给出了满足连通覆盖约束条件的分层传感器网络最大化寿命模型,提出一种非均匀的节点布置算法,通过分析节点的能耗来计算层的宽度,并定量规划了每层中节点的数目。仿真实验表明,基于分层的非均匀节点布置算法能有效延长网络的寿命。On the basis of rectangular deployment field, the authors proposed a layer-based model to maximize the lifetime of sensor networks which met the connectivity coverage constraints, and a non-uniform node deployment algorithm for sensor networks. The width of the layer was decided by node energy consumption. Also, the number of nodes in every layer was determined. Simulation results show that layer-based non-uniform node deployment algorithm can effectively extend the lifetime of the sensor networks.
