Abstract :
Wireless systems have been designed as microcellular architectures in order to provide higher capacity. This reduced coverage area of a cell has caused a higher rate of hand-off events, and providing continuous service to a wireless call after hand-off has been an important issue. A simple and efficient bandwidth reservation scheme is proposed, which dynamically adjusts the amount of bandwidth reserved for hand-off calls in a cell, based on the amount of cellular traffic in its neighboring cells. The performance of the proposed scheme is evaluated and compared with the guard channel scheme which is widely used in current cellular networks
