分析了在AdHoc网络的IEEE802.11DCF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。
The role of extended frame interval EIFS in IEEE802.11DCF in AdHoc networks is analyzed, and the problem of unfairness in DCF is pointed out. A simple solution is given - MDF. Validating MDCF through simulation can significantly improve the unfairness issue.
