In this paper, we propose a distributed admission control scheme based on dynamic bandwidth reservation, with the aid of GPS to trade the position of the mobile terminal (MT) and predict its trajectory. We consider both wireless and wired links as potential bottlenecks and perform reservation in both types of links. By predicting a MT's target handoff cell and its remaining time to handoff, bandwidth reservation can be performed dynamically and efficiently. We perform simulations using an arbitrary hierarchical wireless ATM network with 256 cells, and show that the proposed scheme is able to prioritize handoff requests with moderate tradeoff of the blocking probability for new calls. We also show that the proposed scheme does not affect the amount of bandwidth utilization significantly, and the amount of prediction errors is approximately 1% of the total number of handoffs
