RESERVATION OF CHANNELS FOR HANDOFF USERS IN VISITOR LOCATION BASED ON PREDICTION

The available bandwidth must be efficiently utilized by the mobile user, because the mobile users are increasing gradually nowadays. The main goal of the channel reservation is to reduce the call dropping probability. An efficient channel allocation scheme can significantly reduce call dropping probability. Large number of channel assignment and allocation policies has been proposed. In this paper, the Prediction Based Channel Reservation (PBCR) algorithm is proposed. The PBCR algorithm allows the reservation of a channel for users in target cell before the user moves into that cell. Pre reservations are made when the users are within some distance of the new cell boundary. Channel Borrowing scheme and Queuing scheme are used in this PBCR algorithm for allocating the channel to predicted regular and irregular users. In channel borrowing scheme, free channels are selected from the central pool and optimally allocated to regular user. For irregular user, queuing scheme is applied. These schemes are used to reduce the call dropping probability and utilize the channel bandwidth effectively. So the performance of PBCR algorithm is better when compared to other existing algorithms.
