Age-optimal Sampling and Transmission Scheduling in Multi-Source Systems
Ahmed M. Bedewy, Yin Sun, Sastry Kompella +1
In this paper, we consider the problem of minimizing the age of information in a multi-source system, where samples are taken from multiple sources and sent to a destination via a…
Sampling for Data Freshness Optimization: Non-linear Age Functions
Yin Sun, Benjamin Cyr
In this paper, we study how to take samples at a data source for improving the freshness of received data samples at a remote receiver. We use non-linear functions of the age of in…
Information Aging through Queues: A Mutual Information Perspective
Yin Sun, Benjamin Cyr
In this paper, we propose a new measure for the freshness of information, which uses the mutual information between the real-time source value and the delivered samples at the rece…
Super Fast Beam and Channel Tracking in 2D Phased Antenna Arrays
Yu Liu, Jiahui Li, Yin Sun +1
Millimeter wave (mmWave) is an attractive candidate for high-speed mobile communications in the future. However, due to the propagation characteristics of mmWave, beam and and and…
Joint Beam and Channel Tracking for Two-Dimensional Phased Antenna Arrays
Yu Liu, Jiahui Li, Yin Sun +1
Analog beamforming is a low-cost architecture for millimeter-wave (mmWave) mobile communications. However, it has two disadvantages for serving fast mobility users: (i) the mmWave…
A Dynamic Jamming Game for Real-Time Status Updates
Yuanzhang Xiao, Yin Sun
We study timely status updates of a real-time system in an adversarial setting. The system samples a physical process, and sends the samples from the source (e.g., a sensor) to the…
Achieving the Age-Energy Tradeoff with a Finite-Battery Energy Harvesting Source
Baran Tan Bacinoglu, Yin Sun, Elif Uysal-Biyikoglu +1
We study the problem of minimizing the time-average expected Age of Information for status updates sent by an energy-harvesting source with a finite-capacity battery. In prior lite…
How to Mobilize mmWave: A Joint Beam and Channel Tracking Approach
Jiahui Li, Yin Sun, Limin Xiao +2
Maintaining reliable millimeter wave (mmWave) connections to many fast-moving mobiles is a key challenge in the theory and practice of 5G systems. In this paper, we develop a new a…
High Throughput Low Delay Wireless Multicast via Multi-Channel Moving Window Codes
Fei Wu, Yin Sun, Lu Chen +3
A fundamental challenge in wireless multicast has been how to simultaneously achieve high-throughput and low-delay for reliably serving a large number of users. In this paper, we s…
Age-Optimal Updates of Multiple Information Flows
Yin Sun, Elif Uysal-Biyikoglu, Sastry Kompella
In this paper, we study an age of information minimization problem, where multiple flows of update packets are sent over multiple servers to their destinations. Two online scheduli…
