Abstract
This paper presents a fully distributed Multiple Access Control (MAC) scheme that supports service differentiation in a wireless LAN environment. In the scheme, stations use CSMA for channel access, with collisions between stations having different priorities resolved by sending beacons in a predefined manner. The scheme includes an authentication protocol for stations to join a Basic Service Set and notify their priority level. Both analytical and simulation results are presented for evaluating the performance of the MAC scheme in a two priority level scenario involving voice and data traffic. The proposed scheme has a saturation throughput of about 0.84 with 1000 byte data packets, almost independent of the number of stations. The results show that good service differentiation is achieved among different priority traffic, including support for voice traffic with Quality of Service bounds on the packet latency.
