Version-Aware Communication in Multi-Hop IoT Networks with Feedback
Erfan Delfani, Nikolaos Pappas
Timely communication of information in Internet of Things (IoT) networks is critical to enhancing system performance and energy efficiency by minimizing the transmission of outdate…
From AoI to QVAoI: Query-Based Semantics-Aware Scheduling for Energy-Harvesting IoT Systems
Erfan Delfani, Nikolaos Pappas
In this work, we study the freshness and significance of information in an IoT status update system in which an Energy Harvesting (EH) device samples an information source and forw…
Semantics-Aware Unified Terrestrial Non-Terrestrial 6G Networks
Erfan Delfani, Agapi Mesodiakaki, Leandros Tassiulas +1
The integration of Terrestrial and Non-Terrestrial Networks (TN-NTNs), introduced in 5G, is advancing toward a unified and seamless network of networks in Sixth-Generation (6G). Th…
From Timestamps to Versions: Version AoI in Single- and Multi-Hop Networks
Erfan Delfani, Nikolaos Pappas
Timely and informative data dissemination in communication networks is essential for enhancing system performance and energy efficiency, as it reduces the transmission of outdated…
From Information Freshness to Semantics of Information and Goal-oriented Communications
Jiping Luo, Erfan Delfani, Mehrdad Salimnejad +1
Future wireless networks must support real-time, data-driven cyber-physical systems in which communication is tightly coupled with sensing, inference, control, and decision-making.…
Optimizing Version AoI in Energy-Harvesting IoT: Model-Based and Learning-Based Approaches
Erfan Delfani, Nikolaos Pappas
Efficient data transmission in resource-constrained Internet of Things (IoT) systems requires semantics-aware management that maximizes the delivery of timely and informative data.…
