CARGO: Carbon-Aware Gossip Orchestration in Smart Shipping
Alexandros S. Kalafatelis, Nikolaos Nomikos, Vasileios Nikolakakis +2
Smart shipping operations increasingly depend on collaborative AI, yet the underlying data are generated across vessels with uneven connectivity, limited backhaul, and clear commer…
Toward Goal-Oriented Communication in Multi-Agent Systems: An overview
Themistoklis Charalambous, Nikolaos Pappas, Nikolaos Nomikos +1
As multi-agent systems (MAS) become increasingly prevalent in autonomous systems, distributed control, and edge intelligence, efficient communication under resource constraints has…
On the Interplay Between Deadline-Constrained Traffic and the Number of Allowed Retransmissions in Random Access Networks
Nikolaos Nomikos, Themistoklis Charalambous, Yvonne-Anne Pignolet +1
In this paper, a network comprising wireless devices equipped with buffers transmitting deadline-constrained data packets over a slotted-ALOHA random-access channel is studied. Alt…
A Survey on UAV-Aided Maritime Communications: Deployment Considerations, Applications, and Future Challenges
Nikolaos Nomikos, Panagiotis K. Gkonis, Petros S. Bithas +1
Maritime activities represent a major domain of economic growth with several emerging maritime Internet of Things use cases, such as smart ports, autonomous navigation, and ocean m…
A Survey on Reinforcement Learning-Aided Caching in Mobile Edge Networks
Nikolaos Nomikos, Spyros Zoupanos, Themistoklis Charalambous +2
Mobile networks are experiencing tremendous increase in data volume and user density. An efficient technique to alleviate this issue is to bring the data closer to the users by exp…
Information Freshness and Packet Drop Rate Interplay in a Two-User Multi-Access Channel
Emmanouil Fountoulakis, Themistoklis Charalambous, Nikolaos Nomikos +2
In this work, we combine the two notions of timely delivery of information in order to study their interplay; namely, deadline-constrained packet delivery due to latency constraint…
Relay-Pair Selection in Buffer-Aided Successive Opportunistic Relaying using a Multi-Antenna Source
Themistoklis Charalambous, Su Min Kim, Nikolaos Nomikos +2
We study a cooperative network with a buffer-aided multi-antenna source, multiple half-duplex (HD) buffer-aided relays and a single destination. Such a setup could represent a cell…
A Buffer-aided Successive Opportunistic Relay Selection Scheme with Power Adaptation and Inter-Relay Interference Cancellation for Cooperative Diversity Systems
Nikolaos Nomikos, Themistoklis Charalambous, Ioannis Krikidis +3
In this paper we consider a simple cooperative network consisting of a source, a destination and a cluster of decode-and-forward half-duplex relays. At each time-slot, the source a…
