| Summary: | 碩士 === 銘傳大學 === 資訊傳播工程學系碩士班 === 93 === There are several researches regarding traffic management for sharing the limited bandwidth in wired network; In this thesis we propose a Virtual Distribute Scheduling (VDS) algorithm to dynamically adjust the contention window based on current channel loading by extended the IEEE 802.11e standard. That can perform more fair media access method for each flow with different priority. In addition, the VDS increase the contention window to meet the requirement during deferring periods since channel was busy, vice versa. A simulation is performed evaluate the system performance in term of throughput, delay jitter and the performance of the Quality of service.
