碩士 === 國立雲林科技大學 === 電機工程系碩士班 === 91 === Because the popularity of notebook and PDA, surfing internet at home can not be satisfied by people. WLANs come with the tide of fashion and will be more convenient to let people surf everywhere for work or entertainment. In the past few years, to make WLANs capable of supporting real-time services, a large reseach effort has recently been focused on the optimization of the QoS-MAC performance for the upcoming high-data-rate next-generation WLANs. WLANs are expected to become widely deployed in home-networking environment, and the so-called hot spots to use voice, streaming video, and Web-browsing data services. The IEEE 802.11 Task Group E has been working on a proposal for QoS Enhancements to the IEEE 802.11 MAC, namely the IEEE 802.11e proposed standard. This treatise will focus on the processing way of EDCF of IEEE 802.11e, using Matlab to construct the system simulation and number of the experiment to analyze this program, then make a discussion and suggestions.
