【Abstract】 A key challenge in wireless sensor networks is using the limited energy in a reasonable way in order to maximize the network lifetime.This paper builds a model of network lifetime for wireless sensor networks based on network layer.By analysis of the model,energy-aware routing and data aggregating are proved to be the two crucial factors to save energy.Finally,a network-based energy-aware solution is presented.更多还原
