> 中文摘要: 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.
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.
