A new multiaccess technique for multimedia wireless LANs

This paper presents a novel multiaccess technique that allows multimedia information to be transported in indoor wireless networks. Growing emphasis on multimedia calls for the development of multiaccess protocols capable of supporting demanding applications such as audio/video playback, image browsing, real-time voice/video transmission and interactive data exchange in a unified manner. To this end, a practical multiaccess scheme called “reserved polling” is proposed. The technique handles a diverse mixture of delay classes and message priorities associated with multimedia traffic with an inherent ability to adapt to the traffic load profile. In order to gain a quantitative insight into its behaviour, the protocol is analyzed and simulated in detail
