Statistical Guarantee Optimization for AoI in Single-Hop and Two-Hop Systems with Periodic Arrivals
Jaya Prakash Champati, Hussein Al-Zubaidy, James Gross
Age of Information (AoI) has proven to be a useful metric in networked systems where timely information updates are of importance. In the literature, minimizing "average age" has r…
On the Distribution of AoI for the GI/GI/1/1 and GI/GI/1/2* Systems: Exact Expressions and Bounds
Jaya Prakash Champati, Hussein Al-Zubaidy, James Gross
Since Age of Information (AoI) has been proposed as a metric that quantifies the freshness of information updates in a communication system, there has been a constant effort in und…
Physical Layer Authentication in Mission-Critical MTC Networks: A Security and Delay Performance Analysis
