Medium Access Protocol for Wireless Multimedia Networks

The role of mobile communications in the society is becoming more important every day. The increasing need of a mobile broadband network has driven the intensification of the research efforts in this area. In the wireless LAN field, the 802.11 standard has been a commercial success, making it easy to find products conforming to this standard. But, whenever quality of service is required, the 802.11 fails in supporting flexibly and efficiently real-time requirements. This article describes a wireless MAC algorithm to use with PCNet-Mobile 802.11 cards. Its purpose is to provide access to wireless networks while handling with the quality of service required by the different multimedia applications. Performance results obtained through simulation are presented and discussed.
