A novel channel reservation scheme for handling handoffs in wireless mobile networks

Abstract

This paper proposes a new channel reservation scheme which reserves channels in the neighboring cells for expected handoffs. In mobile communication networks, the radius of the cell becomes smaller so as to utilize the limited channel efficiently. The limited spectrum availability necessitates a novel approach to be addressed to handle handoffs. As the cell radius decreases, the Quality of Service degrades and results in high Handoff dropping rate. In order to handle this issue, a novel reservation based approach is proposed in this paper. The proposed approach reserves channels in the neighboring cells for expected Handoffs. The simulation results reveal that the proposed scheme reduces the dropping probability of handoff calls and guarantees QoS.
