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…
DorFin: WiFi Fingerprint-based Localization Revisited
Chenshu Wu, Zheng Yang, Zimu Zhou +2
Although WiFi fingerprint-based indoor localization is attractive, its accuracy remains a primary challenge especially in mobile environments. Existing approaches either appeal to…
Closing the Price of Anarchy Gap in the Interdependent Security Game
Parinaz Naghizadeh, Mingyan Liu
The reliability and security of a user in an interconnected system depends on all users' collective effort in security. Consequently, investments in security technologies by strate…
