摘要:分析了在Ad Hoc网络的IEEE 802.11 DCF中扩展帧间隔EIFS的作用,指出DCF存在不公平性问题。给出了一个简单的改进方案——MDCF。通过仿真验证MDCF可以显著改善不公平性问题。Abstract:In this paper, the role of the extend interframe spaces in IEEE 802.11 DCF is analyzed, and the potential unfairness problem is illustrated using the DCF in Ad Hoc network. A simple improved scheme, MDCF, is provided. Simulations prove that MDCF can improve the unfairness problem well.
