摘要

利用竞争无线媒介的用户的传输代价不同，本文提出了一种基于网络编码感知的分组公平调度机制FSNC.FSNC机制的基本调度单位是编码集，编码集中的用户将依据自身在编码集中的权重，公平地获取统计上的长期和短期系统服务时间.FSNC机制是通过用户的ARQ反馈消息，感知用户的解码能力从而做出调度决策的.理论和仿真实验证明，FSNC机制在改善多用户分集系统的用户的吞吐率的同时，能够为多用户提供公平的服务时间.

Abstract

In this paper,we exploit the fact that users contending for the wireless medium will have different transmission cost,and present a fairly scheduling scheme FSN C.FSNC adopts NC-aware scheduling while maintaining statistical short and long term fairness.FSNC makes scheduling policy based on the ARQ feedback message fro m users.Theoretic analysis and simulation results prove that FSNC can provide se rvice time fairness while improving the expected good for each user in multiuser diversity system.
