Version Age-of-Information-based Semantic Secrecy Region Analysis
Qian Wang, Bohai Li, Chao Sun +3
This paper investigates semantic secrecy in wireless status-update systems using Version Age of Information (VAoI). We model the fundamental tradeoff between informative updates an…
Optimizing Information Freshness for Cooperative IoT Systems with Stochastic Arrivals
Bohai Li, Qian Wang, He Chen +2
This paper considers a cooperative Internet of Things (IoT) system with a source aiming to transmit randomly generated status updates to a designated destination as timely as possi…
Optimizing Information Freshness in Two-Way Relay Networks
Bohai Li, He Chen, Nikolaos Pappas +1
In this paper, we investigate an amplify-and-forward (AF) based two-way cooperative status update system, where two sources aim to exchange status updates with each other as timely…
Age-Oriented Opportunistic Relaying in Cooperative Status Update Systems with Stochastic Arrivals
Bohai Li, He Chen, Yong Zhou +1
This paper considers a cooperative status update system with a source aiming to send randomly generated status updates to a designated destination as timely as possible with the he…
Signal Design for AF Relay Systems using Superposition Coding and Finite-Alphabet Inputs
Bohai Li, He Chen, Zheng Dong +2
This paper focuses on the signal design in a Gaussian amplify-and-forward (AF) relay system with superposition coding (SC) being applied at the relay, which allows the source and r…
