Dynamic Spectrum Access using Stochastic Multi-User Bandits
Meghana Bande, Akshayaa Magesh, Venugopal V. Veeravalli
A stochastic multi-user multi-armed bandit framework is used to develop algorithms for uncoordinated spectrum access. In contrast to prior work, it is assumed that rewards can be n…
Multi-User Multi-Armed Bandits for Uncoordinated Spectrum Access
Meghana Bande, Venugopal V. Veeravalli
A multi-user multi-armed bandit (MAB) framework is used to develop algorithms for uncoordinated spectrum access. The number of users is assumed to be unknown to each user. A stocha…
Degrees of Freedom in Wireless Interference Networks with Cooperative Transmission and Backhaul Load Constraints
Meghana Bande, Aly El Gamal, Venugopal V. Veeravalli
Degrees of freedom (DoF) gains are studied in wireless networks with cooperative transmission under a backhaul load constraint that limits the average number of messages that can b…
DoF Analysis in a Two-Layered Heterogeneous Wireless Interference Network
Meghana Bande, Venugopal Veeravalli, Antti Tolli +1
Degrees of freedom (DoF) is studied in the downlink of a heterogenous wireless network modeled as a two-layered interference network. The first layer of the interference network is…
