Abstract

This work studies the joint scheduling - admission control (SAC) problem over a fading channel. In particular, the optimal trade-off between maximizing the throughput and minimizing the queue size (or average congestion) is investigated. The SAC problem is formulated as a constrained Markov decision process (MDP) to maximize a utility defined as a function of the throughput and the queue size. The structural properties of the optimal policies are subsequently derived. When the statistical knowledge of the traffic arrival and channel processes is not available, we propose an online learning algorithm for the optimal policies. The analysis and algorithm development are relied on the reformulation of the Bellman's optimality dynamic programming equation using suitably defined value functions which can be learned using online time-averaging.

OtherThe International Conference on Communications (ICC) is one of the two flagship conferences of the IEEE Communications Society, together with IEEE Globecom. Each year the ICC conference attracts about 2-3.000 submitted scientific papers, a technical program committee involving about 1.500 experts provides more than 10.000 reviews, the conference being finally attended by 1.500 - 2.000 professionals from all around the world. IEEE ICC is therefore one of the most significant scientific events of the networking and communications community, a must-attend forum for both industrials and academics working in this area.
