Bandwidth Allocation Strategies for Wireless ATM networks using Predictive Reservation

In future wireless networks such as the Wireless ATM networks, it is important to guarantee quality-of-service (QoS) for mobile terminals. However, guaranteeing QoS while ensuring high bandwidth utilization is difficult because of the unpredictable nature of the terminals mobility pattern. In this paper, we propose a new scheme to improve the QoS of Wireless ATM networks by using predictive reservation of bandwidth from mobility patterns dynamically. We will propose a scheme that use this predictive framework and evaluate their performance. Simulation results show that under heavy load conditions, our proposed scheme will reduce the hand-off dropping probabilities by a significant amount while resulting in only a small increase in the blocking probabilities and a minimal sacrifice in bandwidth utilization
