Ad hoc网络中支持QoS的MAC协议研究
Research on MAC protocols for supporting QoS in mobile Ad hoc networks
【摘要】 支持QoS的MAC协议是Ad hoc网络提供QoS保证的关键。因此,对Ad hoc网络中基于IEEE 802.11 DCF的支持QoS的分布式MAC协议进行了综述,并对该协议的已有研究成果作了分类,阐述了它们的基本原理以及优缺点,同时还讨论了该协议存在的问题和进一步的研究方向。
【Abstract】 The MAC protocols that can support QoS are the key aspects for supporting QoS in Ad hoc networks. In this paper, the distributed MAC protocols supporting QoS based on IEEE 802.11 DCF are introduced. This paper classifies these protocols, describes their main ideas, and analyzes the problems and merits of them. Furthermore, the problems in this area and the future research trend are discussed.
