]]>Our paper Mobility-aware Vehicular Cloud formation mechanism for Vehicular Edge Computing environments has been accepted for the December issue of Elsevier Ad Hoc Networks.
In it, we propose the PREDATOR cloud formation strategy which – other than many previous approaches – also takes into account topology dynamics via mobility prediction. We demonstrate that this design gives PREDATOR an edge over approaches focusing solely on, e.g., current topology, power, or resource availability.
The author’s version is available here. The published version is free to read for 50 days (until 15 November 2023) via the provided link.

In it, Unmanned Aerial Vehicles (UAVs) are investigated as opportunistic airborne network infrastructure for urban wireless networks, providing relaying for cooperative awareness applications and coordinating channel access for platooning without impacting their primary missions. Our results demonstrate that opportunistic UAV relaying yields performance benefits comparable to optimally deployed UAVs, while opportunistic channel access reduces packet collisions by around 86% compared to scenarios without UAVs. Increasing the number of UAVs can partially recover the impact of suboptimal missions.
