UAV Mobility Model for Dynamic UAV-to-Car Communications

Proceedings of the 16th ACM International Symposium on Performance Evaluation of Wireless Ad Hoc, Sensor, & Ubiquitous Networks, 2019
Unmanned Aerial Vehicles (UAVs) can be used to support car-to-car communications when the infrastructures are not available or are unreliable. However, since cars in vehicular communications are mobile, the UAV that acts as a relay should move dynamically as a response to moving ground vehicles.

UAV Selection for a UAV-Based Integrative IoT Platform

2016 IEEE Global Communications Conference (GLOBECOM), 2016
This paper presents a UAV-based integrative IoT platform that leverages UAVs to deliver different IoT services from height. One of the major tasks of the platform is to select the appropriate UAVs for a particular IoT task. This selection may be based on different criteria, such as UAV's equipment, energy budget and geographical proximity of the UAV to
