On the Performance of Irregular Repetition Slotted ALOHA with an Age of Information Threshold
Hooman Asgari, Andrea Munari, Gianluigi Liva
The present paper focuses on an IoT setting in which a large number of devices generate time-stamped updates addressed to a common gateway. Medium access is regulated following a g…
On the Value of Retransmissions for Age of Information in Random Access Networks without Feedback
Andrea Munari
We focus on a slotted ALOHA system without feedback, in which nodes transmit time-stamped updates to a common gateway. Departing from the classical generate-at-will model, we assum…
Information Freshness Analysis of Slotted ALOHA in Gilbert-Elliot Channels
Andrea Munari, Gianluigi Liva
This letter analyzes a class of information freshness metrics for large IoT systems in which terminals employ slotted ALOHA to access a common channel. Considering a Gilbert- Ellio…
Modern Random Access for Beyond-5G Systems: a Multiple-Relay ALOHA Perspective
Andrea Munari, Federico Clazzer
Modern random access protocols are emerging as an efficient yet simple solution for arising internet of things (IoT) applications in upcoming beyond-5G systems. In this context, bo…
Multiple-Relay Slotted ALOHA: Performance Analysis and Bounds
Andrea Munari, Federico Clazzer, Gianluigi Liva +1
Wireless random access protocols are attracting a revived research interest as a simple yet effective solution for machine-type communications. In the quest to improve reliability…
