| Summary: | 碩士 === 國立臺灣師範大學 === 工業教育學系 === 99 === Along with technical development and innovation,a wireless local area network (WLAN)had made rapid progress, and so had the multimedia applications at the same time. All these kinds of service of multimedia applications such as VOD, video conference, and VoIP and so on are real-time, so that the bandwidth distributionis very important. IEEE 802.11e [1]protocol was adopted and the TXOPdisposition on HCCA was taken to improve the efficiency of QoS on this research. This thesis proposed the PID control method, GA algorithms and fuzzy logic theory to improve the efficiency of TXOP distribution on IEEE 802.11e.
At first,TXOP was disposed by adjusting PID parameters, GA algorithms on PID control were integrated, better TXOP was offered by adjusting the gene, and TXOP was disposed by utilizing the fuzzy logic theory and was compared with PID control at the final. Besides, the research took the computer simulation to verify the feasibility and efficiency of the proposed methods, and a comparison study between the proposed methods and the traditional method was given.
