An Adaptive Fractional Guard Channel Based CAC Scheme for Heterogeneous Traffic in Wireless Cellular Networks

In this paper, we propose an adaptive fractional guard channel based call admission scheme for heterogeneous traffic. We have developed a generalised model for investigating the quality of service (QoS) and the effect of mobility of subscribers through simulation and also analysed the results. We evaluate the proposed scheme by computing the new call blocking probability and handoff blocking probability. Moreover, our scheme being relevant to the choice of the wireless medium is extensible to LTE Networks that utilise MIMO wireless technology.
