【Abstract】 Wireless sensor networks(WSNs) are known with high energy constraint,and each network′s lifetime has a strong dependence on the nodes′ battery capacity.How to prolong the network lifetime is a challenge in WSN research.In this paper,we conclude the schemes that improved the energy-efficiency to maximize the networks lifetime based on wireless sensor network architecture in WSN.Finally,conclusion and the future research of networks lifetime in WSN are explored.更多还原
