摘要

中继传输是一种很有前途的技术，可以提高多速率无线个人区域网络(wpan)的吞吐量和能源效率。本文提出了一种基于Wi-Media无线局域网的分布式中继MAC (DR-MAC)协议。DR-MAC扩展了WiMedia MAC中的分布式保留协议DRP (distributed reservation protocol)，可以在信标期间收集中继传输的邻居信息。因此，DR-MAC可以最大限度地减少中继传输的控制开销，并且与标准的WiMedia MAC协议兼容。为了使DR-MAC的效率最大化，我们还介绍了一种介质存取时隙(MAS)的分配方法。与直接传输相比，大量的仿真结果表明，当设备数为20时，DR-MAC的吞吐量提高了10%，能耗降低了26%。

A Distributed Relay MAC Protocol in WiMedia Wireless Personal Area

Relay transmission is a promising technology for improving the throughput and energy efficiency in multi-rate wireless personal area networks (WPANs). In this paper, we propose a distributed relay MAC (DR-MAC) protocol in Wi-Media WPANs. DR-MAC extends a distributed reservation protocol (DRP) in WiMedia MAC and neighbor information for relay transmission can be collected during the beacon period. Therefore, DR-MAC can minimize control overhead for relay transmission and is compatible to the standard WiMedia MAC protocol. We also introduce a medium access slot (MAS) allocation procedure for maximizing the efficiency in DR-MAC. Compared with direct transmission, extensive simulation results demonstrate that DR-MAC can improve the throughput by 10% and reduce the energy consumption by 26% when the number of devices is 20.
