Age Optimal Sampling for Unreliable Channels under Unknown Channel Statistics
Hongyi He, Haoyue Tang, Jiayu Pan +3
In this paper, we study a system in which a sensor forwards status updates to a receiver through an error-prone channel, while the receiver sends the transmission results back to t…
Sampling for Remote Estimation of an Ornstein-Uhlenbeck Process through Channel with Unknown Delay Statistics
Yuchao Chen, Haoyue Tang, Jintao Wang +2
In this paper, we consider sampling an Ornstein-Uhlenbeck (OU) process through a channel for remote estimation. The goal is to minimize the mean square error (MSE) at the estimator…
Sampling of the Wiener Process for Remote Estimation over a Channel with Unknown Delay Statistics
Haoyue Tang, Yin Sun, Leandros Tassiulas
In this paper, we study an online sampling problem of the Wiener process. The goal is to minimize the mean squared error (MSE) of the remote estimator under a sampling frequency co…
Age Optimal Sampling Under Unknown Delay Statistics
Haoyue Tang, Yuchao Chen, Jintao Wang +2
This paper revisits the problem of sampling and transmitting status updates through a channel with random delay under a sampling frequency constraint \cite{sun_17_tit}. We use the…
Sending Timely Status Updates through Channel with Random Delay via Online Learning
Haoyue Tang, Yuchao Chen, Jintao Wang +2
In this work, we study a status update system with a source node sending timely information to the destination through a channel with random delay. We measure the timeliness of the…
Tradeoff between Diversity and Multiplexing Gains in Block Fading Optical Wireless Channels
Sufang Yang, Longguang Li, Haoyue Tang +1
The diversity-multiplexing tradeoff (DMT) provides a fundamental performance metric for different multiple-input multiple-output (MIMO) schemes in wireless communications. In this…
Cache Updating Strategy Minimizing the Age of Information with Time-Varying Files' Popularities
Haoyue Tang, Philippe Ciblat, Jintao Wang +2
We consider updating strategies for a local cache which downloads time-sensitive files from a remote server through a bandwidth-constrained link. The files are requested randomly f…
Minimizing Age of Information with Power Constraints: Multi-user Opportunistic Scheduling in Multi-State Time-Varying Channels
Haoyue Tang, Jintao Wang, Linqi Song +1
This work is motivated by the need of collecting fresh data from power-constrained sensors in the industrial Internet of Things (IIoT) network. A recently proposed metric, the Age…
Optimizing Data Freshness in Time-Varying Wireless Networks with Imperfect Channel State
Haoyue Tang, Jintao Wang, Philippe Ciblat +1
We consider a scenario where a base station (BS) attempts to collect fresh information from power constrained sensors over time-varying band-limited wireless channels. We character…
Age of Information Aware Cache Updating with File- and Age-Dependent Update Durations
Haoyue Tang, Philippe Ciblat, Jintao Wang +2
We consider a system consisting of a library of time-varying files, a server that at all times observes the current version of all files, and a cache that at the beginning stores t…
Scheduling to Minimize Age of Information in Multi-State Time-Varying Networks with Power Constraints
Haoyue Tang, Jintao Wang, Linqi Song +1
In this paper, we study how to collect fresh data in time-varying networks with power constrained users. We measure data freshness from the perspective of the central controller by…
Scheduling to Minimize Age of Synchronization in Wireless Broadcast Networks with Random Updates
Haoyue Tang, Jintao Wang, Zihan Tang +1
In this work, a wireless broadcast network with a base station (BS) sending random time-sensitive information updates to multiple users with interference constraints is considered.…
