Revisiting Optimal Power Control: its Dual Effect on SNR and Contention
Yang Liu, Mingyan Liu, Jing Deng
In this paper we study a transmission power tune problem with densely deployed 802.11 Wireless Local Area Networks (WLANs). While previous papers emphasize on tuning transmission p…
To Stay Or To Switch: Multiuser Dynamic Channel Access
Yang Liu, Mingyan Liu
In this paper we study opportunistic spectrum access (OSA) policies in a multiuser multichannel random access cognitive radio network, where users perform channel probing and switc…
Group Learning and Opinion Diffusion in a Broadcast Network
Yang Liu, Mingyan Liu
We analyze the following group learning problem in the context of opinion diffusion: Consider a network with users, each facing options. In a discrete time setting, at each…
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…
