【摘要】 低占空比无线传感器网络(low-duty-cycle wireless sensor networks,简称LDC-WSN)可以有效地延长网络生命周期.但是,现有的LDC-WSN中端到端的延迟非常大,并且现在很多关于LDC-WSN的算法没有充分考虑传输链路质量的问题.为了解决这两个问题,提出了一种基于链路质量和能量感知的节点休眠调度算法(link-quality and energy-aware based scheduling scheme,简称LES).仿真实验结果表明,相比现在的典型算法,LES算法能够在满足同样延迟要求的情况下很明显地节省能量,从而延长网络的工作寿命.更多还原

【Abstract】 Low-Duty-Cycle wireless sensor networks(LDC-WSN) can effectively increase the lifecycle of wireless sensor networks.However,in traditional LDC-WSN,not only is end-to-end delay very large,but the quality of link is also not considered.In order to solve these two problems,this paper proposes link-quality and energy-aware based scheduling scheme algorithm(LES).Simulation shows that,compared with traditional networks,LES can achieve significant performance improvement in terms of energy-saving and therefore increase life cycle.更多还原
