This work investigates suitable MAC protocols for medical optical wireless body‐area networks (WBANs), focussing on multiple access management. Using realistic channel models, we evaluate the network performance in terms of energy efficiency, quality‐of‐service and scalability for different IEEE protocols, for both intra‐ and extra‐WBAN connectivity in

Trajectory Optimisation for UAV Data Collection in IoT‐Based WSN: A Lévy Flight‐Based Approach
In large‐scale IoT and WSN deployments, data transmission to base stations is often limited by restricted network coverage, and drones can help extend connectivity by collecting data from cluster head nodes. This work proposes an energy‐efficient drone‐assisted data collection approach that jointly optimises system costs and energy consumption, taking ...
