A Game Theory-based Flight Strategy to Energy Efficient UAV-Femtocell Geolocation Systems

UAV-Femtocell systems have been a paragon solution to the challenge of geolocating missing persons in civil protection (e.g. post-earthquake) scenarios. Bearing in mind the limited energy capacity on board a drone, it is extremely critical to provide advanced green UAV communication solutions in this particular application context. This paper proposes a Game Theory-based energy efficiency approach to geolocation of mobile terminals via UAV-Femtocell systems. In particular, this study introduces a statistical analysis of Nash equilibria by providing a simplified version of utility function and extending it to application scenarios characterized by non-isotropic propagation of radio frequency signals. According to research findings, when considering the number of mobile devices in use, drones can save time and energy anywhere from 25% to 66%, if compared to alternative methods introduced in the literature.
