DiG-Park: A Smart Parking Availability Searching Method Using V2V/V2I and DGP-Class Problem

Localization systems for outdoor areas using GNSS based systems (like GPS, GLONASS and more) are nowadays widespread and commonly-available in devices like smartphones. For indoor localization, on the other hand, several methods has been proposed in the latest years, like inertial navigation systems (INS) or wireless positioning systems (WPS, like wireless trilateration or fingerprinting methods), but an always-available and reliable technology is still under research. Vehicle-2-vehicle and Vehicle-2-infrastructure technologies allow vehicles to communicate via wireless to issue security warnings and to share traffic information. In this paper we propose an alternative localization technique based on the presence of nearby vehicles and known fixed infrastructures like generic radio hotspots. We aim to improve localization accuracy of the user in indoor parking lots using a combination of wireless radio signal strenght-to-distance evaluation, V2V/V2I, and a DGP algorithm, allowing users to rapidly find a free parking spot. This grade of accuracy is mandatory in indoor car park scenario since the vehicles are very close one to another in comparison with normal road traffic.
