基于流的 AD Hoc 网络接入公平性分析与研究
Analysis and Research of MAC Fairness in Ad Hoc Network Based on Flow
摘要
Abstract
In Ad Hoc network, the unfairness of the system will affect the quality of service seriously. This paper presents a mechanism using flow unit and Weighted Fairness Queuing(WFQ) for scheduling local information, and the coordination algorithm that the exchange of node information to adjust the backoff time — Fairness Base Flow Algorithm(FBFA). The algorithm calculates every flow's services index for each node, and exchanges with the neighbor nodes, combining with the node's own information and neighbor node information to determine the backoff time to improve the system fairness. Because FBFA algorithm takes into account the system's local and global fairness and throughput, experimental results show that system's fairness index has 10％～20％ increases.关键词
