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 di#cult 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-o # dropping probabilities by a signi#cant amount while resulting in only a small increase in the blocking probabilities and a minimal sacri#ce in bandwidth utilization. 1, |
