Broadcast and aggregation in BBC
Hans Hüttel, Nuno Pratas
In distributed systems, where multi-party communication is essential, two communication paradigms are ever present: (1) one-to-many, commonly denoted as broadcast; and (2) many-to-…
Effect of LOS/NLOS Propagation on Ultra-Dense Networks
Carlo Galiotto, Nuno K. Pratas, Linda Doyle +1
This paper aims at investigating the achievable performance and the issues that arise in ultra-dense networks (UDNs), when the signal propagation includes both the Line-of-Sight (L…
Massive M2M Access with Reliability Guarantees in LTE Systems
German Corrales Madueno, Nuno K. Pratas, Cedomir Stefanovic +1
Machine-to-Machine (M2M) communications are one of the major drivers of the cellular network evolution towards 5G systems. One of the key challenges is on how to provide reliabilit…
Joint Estimation and Contention-Resolution Protocol for Wireless Random Access
Čedomir Stefanović, Kasper F. Trilingsgaard, Nuno K. Pratas +1
We propose a contention-based random-access protocol, designed for wireless networks where the number of users is not a priori known. The protocol operates in rounds divided into e…
Code-Expanded Random Access for Machine-Type Communications
Nuno K. Pratas, Henning Thomsen, Cedomir Stefanovic +1
The random access methods used for support of machine-type communications (MTC) in current cellular standards are derivatives of traditional framed slotted ALOHA and therefore do n…
