Using Age of Information for Throughput Optimal Spectrum Sharing
Hongjae Nam, Vishrant Tripathi, David J. Love
We consider a spectrum sharing problem where two users attempt to communicate over N channels. The Primary User (PU) has prioritized transmissions and its occupancy on each channel…
AoI-based Scheduling of Correlated Sources for Timely Inference
Md Kamran Chowdhury Shisher, Vishrant Tripathi, Mung Chiang +1
We investigate a real-time remote inference system where multiple correlated sources transmit observations over a communication channel to a receiver. The receiver utilizes these o…
Online Learning of Whittle Indices for Restless Bandits with Non-Stationary Transition Kernels
Md Kamran Chowdhury Shisher, Vishrant Tripathi, Mung Chiang +1
The restless multi-armed bandit (RMAB) framework is a popular approach to solving resource allocation problems in networked systems. In this paper, we study optimal resource alloca…
Timely Trajectory Reconstruction in Finite Buffer Remote Tracking Systems
Sunjung Kang, Vishrant Tripathi, Christopher G. Brinton
Remote tracking systems play a critical role in applications such as IoT, monitoring, surveillance and healthcare. In such systems, maintaining both real-time state awareness (for…
Communication-Efficient Cooperative Localization: A Graph Neural Network Approach
Yinan Zou, Christopher G. Brinton, Vishrant Tripathi
Cooperative localization leverages noisy inter-node distance measurements and exchanged wireless messages to estimate node positions in a wireless network. In communication-constra…
Optimizing Age of Information in Networks with Large and Small Updates
Zhuoyi Zhao, Vishrant Tripathi, Igor Kadota
Modern sensing and monitoring applications typically consist of sources transmitting updates of different sizes, ranging from a few bytes (position, temperature, etc.) to multiple…
