Slotted Aloha for Optical Wireless Communications in Internet of Underwater Things
Milica Petkovic, Sotiris A. Tegos, Panagiotis D. Diamantoulakis +4
In this work, we design and analyse a Slotted ALOHA (SA) solution for Optical Wireless Communication (OWC)-based Internet of Underwater Things (IoUT). In the proposed system, user…
Two-Tier Multi-Rate Slotted ALOHA for OWC/RF-Based IoT Networks
Milica Petkovic, Dejan Vukobratovic, Andrea Munari +1
We consider a massive Internet of Things (IoT) scenario where indoor IoT devices access the network via optical wireless communication (OWC) IoT systems that relay data via a backh…
Error Rate and Ergodic Capacity of RF-FSO System with Partial Relay Selection in the Presence of Pointing Errors
