Age of Information under Source-Aware Truncated ARQ in Multi-Source Wireless Status Updating
Tianci Zhang, Aobo Liu, Zhengchuan Chen +4
This paper studies information timeliness in multi-source wireless Internet of Things (IoT) status updating systems under a truncated Automatic Repeat reQuest (ARQ) protocol. We pr…
Absorbing Markov Chain-Based Analysis of Age of Information in Discrete-Time Dual-Queue Systems
Yifan Feng, Nail Akar, Zhengchuan Chen +1
Status update systems require the timely collection of sensing information for which deploying multiple sensors/servers to obtain diversity gains is considered as a promising solut…
The Dispersion of Broadcast Channels With Degraded Message Sets Using Gaussian Codebooks
Zhuangfei Wu, Lin Bai, Jinpeng Xu +2
We study the two-user broadcast channel with degraded message sets and derive second-order achievability rate regions. Specifically, the channel noises are not necessarily Gaussian…
On Finite Blocklength Lossy Source Coding
Lin Zhou, Mehul Motani
In this monograph, we review recent advances in second-order asymptotics for lossy source coding, which provides approximations to the finite blocklength performance of optimal cod…
Throughput Maximization with an Average Age of Information Constraint in Fading Channels
Rajshekhar Vishweshwar Bhat, Rahul Vaze, Mehul Motani
In the emerging fifth generation (5G) technology, communication nodes are expected to support two crucial classes of information traffic, namely, the enhanced mobile broadband (eMB…
Generalized Sphere-Packing Bound for Subblock-Constrained Codes
Han Mao Kiah, Anshoo Tandon, Mehul Motani
We apply the generalized sphere-packing bound to two classes of subblock-constrained codes. A la Fazeli et al. (2015), we made use of automorphism to significantly reduce the numbe…
