A dynamic reservation protocol for multi-priority multi-rate data services on GSM networks

This paper presents a new media access control protocol for multi-priority multi-rate data services on GSM networks. In this protocol, which we named dynamic reservation protocol, data terminals can get their uplink channels through contention-free reservation. Therefore this protocol can achieve very high channel utilization efficiency and can significantly improve the service performance under heavy traffic load. The reservation scheme can adapt to traffic variations, by dynamically changing the transmission cycle length. Simulation results show that this protocol offers significantly better delay/throughput performance when compared to other protocols proposed in the literature. Since this protocol is built on the top of the GSM physical layer, its implementation should be very straight forward.
