Max-Min Energy-Efficiency Fair Optimization in STAR-RIS Assisted System
Ruitianyi Lu, Kehao Wang
In this paper, we investigate simultaneously transmitting and reflecting reconfigurable intelligent surfaces (STAR-RIS), which enables to communicate with users both sides by trans…
Optimality of Myopic Policy for Restless Multiarmed Bandit with Imperfect Observation
Kehao Wang
We consider the scheduling problem concerning N projects. Each project evolves as a multi-state Markov process. At each time instant, one project is scheduled to work, and some rew…
Finding Needles in a Haystack: Missing Tag Detection in Large RFID Systems
Jihong Yu, Lin Chen, Kehao Wang
Radio frequency identification (RFID) technology has been widely used in missing tag detection to reduce and avoid inventory shrinkage. In this application, promptly finding out th…
From Static to Dynamic Tag Population Estimation: An Extended Kalman Filter Perspective
Jihong Yu, Lin Chen
Tag population estimation has recently attracted significant research attention due to its paramount importance on a variety of radio frequency identification (RFID) applications.…
Pricing Mobile Data Offloading: A Distributed Market Framework
Kehao Wang, Francis C. M. Lau, Lin Chen +1
Mobile data offloading is an emerging technology to avoid congestion in cellular networks and improve the level of user satisfaction. In this paper, we develop a distributed market…
On Optimality of Myopic Policy for Restless Multi-armed Bandit Problem with Non i.i.d. Arms and Imperfect Detection
Kehao Wang, Lin Chen, Quan Liu +1
We consider the channel access problem in a multi-channel opportunistic communication system with imperfect channel sensing, where the state of each channel evolves as a non indepe…
On Optimality of Myopic Sensing Policy with Imperfect Sensing in Multi-channel Opportunistic Access
Kehao Wang, Lin Chen, Quan Liu +1
We consider the channel access problem under imperfect sensing of channel state in a multi-channel opportunistic communication system, where the state of each channel evolves as an…
On Optimality of Greedy Policy for a Class of Standard Reward Function of Restless Multi-armed Bandit Problem
Quan Liu, Kehao Wang, Lin Chen
In this paper,we consider the restless bandit problem, which is one of the most well-studied generalizations of the celebrated stochastic multi-armed bandit problem in decision the…
On the Optimality of Myopic Sensing in Multi-channel Opportunistic Access: the Case of Sensing Multiple Channels
Kehao Wang, Lin Chen
Recent works have developed a simple and robust myopic sensing policy for multi-channel opportunistic communication systems where a secondary user (SU) can access one of N i.i.d. M…
