摘要
能耗是无线传感网络研究的核心问题,也是其网络性能重要参数之一。WSNs节点的生存周期主要取决于节点的能量消耗,针对无线传感网络WSNs低速率的特点,本文对其网络节点能耗做了分析研究,讨论无线传感网络MAC层的能耗管理与节能措施,从周期性监听和睡眠,冲突和串音避免,长信息传递等方面介绍与分析了S-MAC协议在WSNs中节能的合理性与实用性。
Energy consumption is the primary goal of the rearch on wirless sensor networks,also one of the important performance parameters. Survival cycle of the node in wirless sensor networks is depended upon the energy consumption. The article analyzes the energy consumption of the nodes in networks,discusses the energy consumption management and energy conservation measurement of MAC layer in Wireless Sensor Networks（WSNs）as to its low rate feature, and then it also introduces S- MAC protocol from periodic sleep and listening,avoidance of conflict and crosstalk,and message passing, so the rationality and usability of S - MAC in energy conservation of WSNs are explained.
