Abstract:
The allocation of scare spectral resources to support as many user running multimedia applications as possible while maintaining acceptable quality of service (QoS) is a fundamental problem in next generation wireless cellular networks. In this paper, we propose an adaptive bandwidth framework which aims at providing an effective management of the limited radio resources in wireless cellular networks. The framework consists of two integrated components, call admission control module and adaptive bandwidth allocation (ABA) module. The framework is designed to take advantage of the ABA module with new calls and handoff calls in order to provide an acceptable trade off between new call blocking and handoff call dropping probabilities. The elaborate simulation is conducted to verify the performance of the framework in terms of new call blocking probability, handoff call dropping probability, and bandwidth utilization.
