主 题:sensor networks lifetime distribution multiple base stations
摘 要:A large sensor network needs multiple base stations(BSs) to collect data *** design effort often aims at maximizing the network *** lifetime of a network depends on,besides battery capacity,factors such as node density,sampling period and the partitioning of the network for the multiple base *** this paper,we propose a stochastic approach to finding the lifetime of large sensor networks with multiple BSs and randomly scattered *** begin by partitioning the network into regions by the Voronoi diagram method,one for each base *** then propose a method to find the minimum transmission range needed for guaranteeing network *** nodes connected,we derive the traffic rate of nodes at specific distance from the base *** on the traffic rate and energy consumption model,the lifetime distribution of a region is *** the results of individual regions,the network lifetime distribution is *** studies are presented and verified by computer simulation.
