Smart vehicles are considered key enablers for intelligent transport systems. They are equipped with components to enable services for vehicle occupants, other vehicles on roads, and third parties. In-vehicle sensors, diversified communication modules, and an on-board unit with high computing and storage capabilities enable the smart vehicle to work as a mobile resource of diverse scopes of services. With the high benefits the public sensing paradigm brought to the application domain, there is interest nowadays to widen the scope of applications by engaging more resources in the sensing loop. Although smartphones have been the main players in this domain, their use suffers from limitations due to the scarcity of their on-board resources and their unpredictable mobility patterns. Concurrently, the plethora of on-board resources in smart vehicles along with their ubiquitous mobility are pushing towards utilizing them for providing remarkable public sensing services. In this thesis, we unveil the different resources a smart vehicle can provide on roads or at parking lots highlighting diversified information services that can come into action through utilizing such resources. Motivated by the high rise of the public sensing paradigm, we propose a vehicular public sensing platform that aims at exploiting the sensing, storage, processing and relaying resources of smart vehicles for provisioning ubiquitous, sensing-based information services. As parts of the proposed platform, we present a collection of solutions to handle some challenges facing such use of vehicles for public sensing. Our proposed solutions involve a framework to handle reputation-aware recruitment and selection of smart vehicles for achieving desired coverage of an area of interest within a budget limit. In addition, the presented solutions involve a data delivery scheme that considers on-road caching and forwarding assistance in accessing the sensing-based vehicular resources targeting improving the incurred access cost and delay. Extensive performance evaluation is conducted showing the improvements achieved by the proposed solutions in their targeted objectives compared to other popular systems and schemes.
