Abstract

Nowadays, it is a popular life trend to surf on the Internet, make a phone call and watch video by the portable terminals anytime and anywhere. Especially at the crowded commercial areas, exhibition halls, airports, the number of users are a lot but the wireless access points APs is limited, the traffic of video and audio through WLAN increases sharply. This kind of traffic has high performance requirements on the end-to-end delay of network.. This paper proposed a new improved access scheme in order to solve the real-time performance insufficient of transmission traffic when multiple access through the PCF protocol. The improved access scheme changed the polling and sorting of PCF to the competition and sorting .This effectively reduced the end-to-end delay of network ,ensured that the transmission delay can meet the requirements of real-time streaming and improved the transmission quality of the real-time streaming. This paper also compared the performance of several mechanisms of IEEE 802.11 MAC. Simulation results illuminates that the improved mechanism is able to increase throughput of the Internet as well as keep a comparatively short delay of end-to-end connection.
