Efficient resource reservation scheme with optimal channel requests classification in cellular systems

This paper proposes the time-based bandwidth reservation (TBR) based on real-time measures of mobiles (position, velocity and acceleration). The scheme consists in sending reservation requests to the neighboring cells based on an extrapolation of the mobile users motion. The goal of our scheme is to adjust the amount of time for which bandwidth has to be allocated and reserved in a cell. We have also proposed an optimal channel requests arrangement (CRA) algorithm in order to improve the performance of TBR. Performance of the proposed scheme (with and without CRA) and comparison with guard channel scheme are presented. The simulation results show that the proposed TBR scheme can efficiently improve the connection dropping probability
