  Abstract

Heavy utilization of a certain portion of spectrum results from significant competence of the free spectrum such as ISM (industrial, scientific, and medical) bands. This spectrum scarcity introduces cognitive radio (CR) concept. Existing cognitive radio MAC protocols have only focused on avoiding primary user's service interruption. However, their approaches have not taken into account secondary users' seamless transmission. A way of guaranteeing secondary users' QoS has remained a unsolved challenges. In this paper, we propose an admission control scheme to guarantee secondary user's QoS. The proposed admission control scheme exploits primary users' arrival pattern and guarantee primary as well as secondary user's seamless transmission. Through performance evaluation, we have shown that the proposed admission control scheme can effectively reduce primary users' blocking probability by 1/40 or more, and improve the secondary users' seamless communication by 90% and thus provide stationary throughput.
