Abstract

The bandwidth adaptation is the technique that allows the flexibility in bandwidth allocation for a call. Using the bandwidth adaptation technique, the number of call admission in the system can be increased significantly. In this paper we propose a priority based bandwidth adaptation scheme that can release multi-level of bandwidth from the existing calls to accept call requests. The amount of released bandwidth is based on the number of existing bandwidth adaptive calls and the priority of requesting traffic call. This priority scheme does not reduce the bandwidth utilization. Moreover, the proposed bandwidth adaptation strategy provides significantly reduced call blocking probability for the higher priority traffic calls. The performance analyses show the improvement of the proposed scheme.
