Abstract

We propose a medium access control (MAC) architecture for IEEE 802.11-like WLANs supporting multimedia services. The novel access algorithm, maintaining a Diffserv-like traffic classification, shows a remarkable improvement in all performance measures of the multimedia traffic, especially in heavy load situation.
