Abstract :
This paper proposes an adaptive resource management scheme for multimedia services in a wireless network environment. The proposed scheme attempts to allocate the desired bandwidth to every multimedia connection originating in a cell or being handed off to the cell. In case of insufficient bandwidth and in order not to deny service to requesting connections, bandwidth adaptation is done. However, to improve upon the hand-off dropping probability, the proposed bandwidth adaptation algorithm has a provision for giving preference to hand-off calls over new calls. The scheme also ensures that the borrowed bandwidth is promptly returned to the degraded connections. Simulation results show that the proposed scheme outperforms the previous known schemes in terms of call dropping probability, call blocking probability and bandwidth utilization.
