Sufficient Conditions on the Optimality of Myopic Sensing in Opportunistic Channel Access: A Unifying Framework
Yang Liu, Mingyan Liu, Sahand Haji Ali Ahmad
This paper considers a widely studied stochastic control problem arising from opportunistic spectrum access (OSA) in a multi-channel system, with the goal of providing a unifying a…
Spectrum Sharing as Spatial Congestion Games
Sahand Ahmad, Cem Tekin, Mingyan Liu +2
In this paper, we present and analyze the properties of a new class of games - the spatial congestion game (SCG), which is a generalization of the classical congestion game (CG). I…
Spectrum Sharing as Network Congestion Games
Sahand Ahmad, Cem Tekin, Mingyan Liu +2
This paper has been withdrawn by the first author due to incomplete bibliography and incorporation of multiple formats in the same file.
Congestion games with resource reuse and applications in spectrum sharing
Sahand Haji Ali Ahmad, Mingyan Liu, Yunnan Wu
In this paper we consider an extension to the classical definition of congestion games (CG) in which multiple users share the same set of resources and their payoff for using any r…
Multi-channel Opportunistic Access: A Case of Restless Bandits with Multiple Plays
Sahand Haji Ali Ahmad, Mingyan Liu
This paper considers the following stochastic control problem that arises in opportunistic spectrum access: a system consists of n channels (Gilbert-Elliot channels)where the state…
Optimality of Myopic Sensing in Multi-Channel Opportunistic Access
Sahand H. A. Ahmad, Mingyan Liu, Tara Javidi +2
We consider opportunistic communications over multiple channels where the state ("good" or "bad") of each channel evolves as independent and identically distributed Markov processe…
