摘要

本文分析比较了几种改进的介质访问控制(MAC)协议和CSMA/CA协议在高数据速率(至少1gbps)下的性能,提出了一种新的介质访问控制协议——伪时分回退方案(PTDBS)。该方案易于在IEEE 802.15.3c环境下实现,可以成为现有IEEE 802.15.3 MAC争用访问期(CAP)访问控制的一种改进方法。结果表明,与CSMA/CA协议和其他改进的MAC协议相比,PTDBS具有更高的吞吐量、更低的延迟和接近1的完成率。

A novel MAC protocol for IEEE 802.15.3C
This paper analyzes and compares performances of several improved medium access control (MAC) protocols and CSMA/CA protocol when the data rate is high (at least 1 Gbps), then proposes a novel MAC protocol, called pseudo-time division backoff scheme (PTDBS). The proposed scheme can be implemented in IEEE 802.15.3c easily and it can become an improved access control method in contention access period (CAP) for existing IEEE 802.15.3 MAC. PTDBS has been validated using OPNET network simulator. The results show that PTDBS offers higher throughput, lower delay and completion rate of close to one when the traffic load is heavy compared with the CSMA/CA protocol and other improved MAC protocols.
