Abstract
AbstractLocalization of vehicles is crucially important for network level operations and application level performance in Internet of Vehicles (IoV). Nowadays, vehicle positioning is being achieved using vehicle mounted global positioning system (GPS). But, it is highly expensive and not apt for wireless sensor networks with indoor applications. We propose GPS-free localization technique using vehicle-to-infrastructure (V2I) using directional antennas of road side units (RSUs). It is highly suitable for cost optimization of IoV-based applications both outdoor and indoor applications (absence of GPS signal). In this paper, we estimate Angle of Arrival (AOA) using the beacon messages released by RSUs. The proposed approach does not require any assumption of availability of prior knowledge of vehicle. The proposed technique for localization of vehicle is computed experimentally using ns-2 simulations. The comparison is made with state-of-art methods for localization using GPS and without GPS. The experimental results show that presented localization strategy exhibits more accuracy than the state-of-the-art methods.KeywordsLocalizationInternet of vehicle (IoV)Global positioning system (GPS)Roadside unit (RSU)Directional antenna
