摘要
由于受到传感器网络节点数量巨大和能量有限的限制,设计一种节能的MAC协议是非常必要的,也是当前此领域的研究重点之一。现给出了无线传感器网络中引起能量浪费的主要因素,综述了无线传感器网络MAC协议最新的研究进展,讨论了MAC层节能技术,为无线传感器网络中MAC协议的进一步研究提供了有价值的参考。
It becomes necessary to achieve an energy - efficient medium - access protocol subject to power constraints and large scale, so it is also the one of key points in the research. This article discussed on the main reasons of the energy wasting, and introduces the recent researches on MAC protocol, the energy - efficient technology and its research trend in the wireless sensor networks. The valuable consults for further MAC protocol research on wireless sensor networks are provided in this article.
