Abstract

In this paper, we have proposed an augmented random access MAC protocol for cognitive radio network (CRN) called ACR-MAC. We have presented analytical framework for the proposed protocol, and developed closed form expressions for saturated throughput and average packet delay. The performance of the proposed protocol has been examined with the performance of cognitive radio MAC protocol which was developed based on the well-known distributed coordination function (DCF) which deploys two medium access mechanisms: the basic and RTS/CTS. The proposed MAC protocol shows promising performance in terms of saturated throughput and average packet delay over the conventional random access MAC protocol proposed for CRN.
认知无线网络增强型随机接入MAC协议(ACR-MAC)
本文提出了一种用于认知无线网络(CRN)的增强型随机接入MAC协议ACR-MAC。我们提出了该协议的分析框架,并开发了饱和吞吐量和平均数据包延迟的封闭形式表达式。基于分布式协调函数(DCF)开发的认知无线电MAC协议部署了基本和RTS/CTS两种介质访问机制,并对该协议的性能进行了测试。本文提出的MAC协议在饱和吞吐量和平均数据包延迟方面都比CRN中提出的传统随机接入MAC协议有更好的性能。
