Design and performance evaluation of new channel reservation schemes for supporting multi-class traffics

We consider a single-access system where high bit-rate communication systems constrain the propagation delay between users and the base station. We found that existing channel reservation schemes cannot guarantee satisfaction to all users regarding different quality of service (QoS). Thus, we propose two new channel reservation schemes which take into consideration priority service to more delay-sensitive traffics, namely, UNI+DS (uniform and divided slots) and UNI+DS+MLA (uniform with divided slots and multiple limited access) schemes, an extension of our recently proposed UNI (uniform) scheme for single-class traffic. The goal is to achieve the highest system performance and enable each traffic type to meet its QoS requirements. We evaluate the performance of each scheme by mathematical analysis. The numerical results show that our proposed schemes are effective in enabling different traffic users to achieve the best successful rate possible in this kind of environment
