However the performance of EDCF may be poor in some cases. Thus, a modified EDCF, MEDCF is presented in this paper, which can supply different multiple access techniques to services with different requirements on QoS, such as p-persistent CSMA/CA for real-time service and non-persistent CSMA/CA for non-real-time service. Analysis and simulation show that MEDCF can support multimedia service and assure quality of real-time service. 关键词： WLAN, IEEE 802.11, DCF, EDCF, QoS (浏览全文) 发表日期： 2006年09月05日 同行评议：
