In this study, we address the problem of minimizing the energy consumption in future 5G networks by means of a joint optimization of radio access network (RAN) and multi-hop wireless backhaul network. The objective of the optimization is to operate the network with the smallest set of base stations while meeting the quality of service (QoS) requirements of users. We first pose the optimization problem...
Multi-armed bandit games form a class of sequential optimization problems, in which a player sequentially pulls an arm, selected from a known and finite set of arms, in order to receive an a priori unknown reward. Since the player does not know the arm with the highest reward in advance, it utilizes a well-designed selection strategy to minimize the so-called regret, which, roughly speaking, results...
A key to efficient mobile communication networks is an efficient utilization of scarce resources, which includes mechanisms for resource allocation and interference management. In practice, time sharing methods such as Time Division Multiple Access (TDMA) are often exploited to create orthogonal connections. TDMA schemes however are inflexible and not suitable for decentralized implementation. In...
