摘　　要：将地理位置路由应用于多基站数据聚合无线传感器网络以最大化网络生命期。为减少传输开销并避免路由环路,提出了归属基站集合降势法,采用线性规划方法优化网络生命期。提出了基于地理位置的多基站剖分法,采用次梯度方法设计了分布式算法。通过仿真实验验证了所提算法的性能。Network lifetime maximization in data-aggregated wireless sensor networks with multiple base stations by using geographic routing scheme was studied.To reduce the transmission overhead and avoid routing loops,home base station set potential descendent（HBSPD） algorithm was proposed,and linear programming method was used to optimize the network lifetime.Geographic location based multiple base station tessellation（GLMBST） algorithm was presented,and subgradient method was adopted to design the distributed algorithm.Performances of the proposed algorithms were verified by simulation experiments.
