基于移动sink的WSN节能技术研究综述

s sensor nodes are generally battery-powered devices, the critical aspects to face concern how to reduce the energy consumption of nodes, so that the network lifetime can be extended to reasonable times. Research have shown that mobile sink can effectively improve throughput, lifetime and reliability of the large-scale sensor network. This paper firstly investigates the theoretical aspects of the uneven energy depletion phenomenon around a sink. Then addresses the problem of energy-e?cient data gathering by mobile sinks and present a taxonomy survey of state of existing solutions. Finally, we conclude the paper with insights for research directions about energy conservation in WSN with mobile sink.
