基于多信道的MAC层协议在无线传感器网络中的应用

摘要：随着无线传感器网络在工业测控,医疗监护和智能建筑等领域的迅速发展，使用单一信道和信道竞争的MAC层协议已经很难满足这些应用的低功耗、抗干扰、高可靠性和可预测可控制时延等要求.基于多信道的MAC层协议是满足这些应用要求的一个重要手段.本文提出了系统的对多信道MAC层协议的分类方法，并总结和比较了到目前为止在无线传感器网络多信道MAC层协议方面的主要研究工作和国际标准化协议的研究进展，最后提出了在这个领域的若干研究课题和发展方向.

Multi-channel MAC protocols for wireless sensor networks:a survey

With rapid deployment and application of wireless sensor network technology in the area of industrial instrumentation and control,remote medical care,intelligent buildings,etc.,traditional contention-based MAC layer protocols using a single channel cannot satisfy low power consumption,high interference resistance,high reliability and predictable time delay requirements posed by these applications. The multi-channel based MAC protocol is a very promising approach to meet these challenges. In this article,we ...
