Towards Realistic Waveform-Level IoT Network Simulation via IQ Mixing
Alexis Delplace, Samer Lahoud, Kinda Khawam +1
Most Internet of Things (IoT) network simulators are packet-level discrete-event systems in which physical-layer (PHY) behavior is approximated through analytical interference rule…
Exploring LR-FHSS Modulation for Enhanced IoT Connectivity: A Measurement Campaign
Alexis Delplace, Samer Lahoud, Kinda Khawam
This paper presents the first comprehensive real-world measurement campaign comparing LR-FHSS and LoRa modulations within LoRaWAN networks in urban environments. Conducted in Halif…
Semantic Communication with Distribution Learning through Sequential Observations
Samer Lahoud, Kinda Khawam
Semantic communication aims to convey meaning rather than bit-perfect reproduction, representing a paradigm shift from traditional communication. This paper investigates distributi…
Client Selection Strategies for Federated Semantic Communications in Heterogeneous IoT Networks
Samer Lahoud, Kinda Khawam
The exponential growth of IoT devices presents critical challenges in bandwidth-constrained wireless networks, particularly regarding efficient data transmission and privacy preser…
Fragment-Level Macro-Diversity Reception in LoRaWAN Networks with LR-FHSS
Samer Lahoud, Kinda Khawam
