摘要

针对具有连续性接入需求的业务,论文融合时分多址接入技术和竞争窗口差分服务机制,提出了具有连续性保障的无线接入协议:CP-MAC (MAC with Continuity Provisioning)协议.通过对业务等级划分,保障了连续用户的接入概率.并基于Markov模型,给出了非饱和认知无线电网络的系统容量,接入时延和被阻塞概率的数学解析式.最后,通过与现存的MAC接入协议比较,CP-MAC协议在不降低系统容量的同时,提高了连续用户的接入概率,并降低了其接入时延.

Abstract

This paper proposes a new media access control protocol with continuity provisioning (CP-MAC) by converging time division multiple access and contention window differential service mechanism for the continuous services.The continuous access probability would be guaranteed by a priority method.We give the mathematical framework by Markov chain model in terms of the system capacity,latency and the blocked gain of the general users in unsaturated networks.Compared with the current protocols,CP-MAC can access the network with a higher probability and lower latency while there is no any system capacity loss for the continuous users.
