Bandwidth reservation in mobile cellular networks using ITS navigation systems

We demonstrate how to utilize the path information available from ITS navigation systems for bandwidth reservation for hand-off and admission control of new connections in mobile cellular networks. By utilizing the path information, we modify the recently proposed bandwidth reservation and admission control scheme with a design goal to keep the hand-off dropping probability below a pre-specified target. While the original scheme utilized a history-based mobility estimation, the modified scheme eases only part of it. Since both the original and modified schemes meet the design goal, the problem is to determine which of the two can admit more new connections for a given traffic condition. Using simulations, the modified scheme aided by the-navigation system is shown to outperform the original scheme even with much less computational requirement.
