Multiple access scheme to support the integration of real-time and bursty traffics

Future wireless systems will allow the mobile access to multimedia services. This paper proposes a medium access control (MAC) protocol that permits an efficient integration of real time-variable bit rate (rt-VBR) traffic and bursty available bit rate (ABR) traffic. This scheme, named minislotted-dynamic resource assignment (M-DRA), provides rt-VBR sources with a quality of service independent of the ABR traffic load. The M-DRA scheme effectiveness has been validated by comparisons with other protocols.
