A time-based bandwidth reservation scheme in cellular networks

In this paper, we propose and evaluate a new scheme for bandwidth reservation in cellular networks. This scheme called time-based bandwidth reservation (TBR) consists in sending reservation requests to the neighboring cells based on real-time measures of mobiles (position, velocity and acceleration). The goal of our scheme is to adjust the amount of time for which bandwidth has to be allocated and reserved in a cell. Detailed performance results of TBR scheme and comparison with guard channel scheme are presented. The simulation results show that the proposed TBR scheme can efficiently improve the connection dropping probability.
