Abstract

The use of unscheduled contention based channel access protocols in mobile ad hoc networks is very attractive due to their transparency to topological change, relatively low overhead, and ease of implementation. Recent reports (see Shugong Xu and Tarek Saadawi, IEEE Commun. Magazine, vol.39, no.6, p.130-7, 2001), however, have shown that the widely available asynchronous contention based 802.11 protocol has significant fairness issues, especially with regard to exposed terminals. These fairness issues are a direct result of the asynchronous nature of the protocol. We present SUMA, the synchronous unscheduled multiple access protocol, which has all the benefits of a contention based access protocol while ensuring fair access to all nodes.
SUMA——用于移动自组织网络的同步非预定多址协议
在移动自组织网络中使用基于非计划争用的通道访问协议非常有吸引力,因为它们对拓扑变化透明,开销相对较低,易于实现。最近的报告(见Shugong Xu和Tarek Saadawi, IEEE common)。杂志,第39卷,no。6, p.130-7, 2001),然而,已经表明,广泛可用的基于异步争用的802.11协议有显著的公平性问题,特别是关于暴露的终端。这些公平性问题是协议异步特性的直接结果。我们提出了同步非调度多访问协议SUMA,它具有基于争用的访问协议的所有优点,同时确保对所有节点的公平访问。
