Abstract
The cutting-edge technologies have improved the journey of vehicle users on the road using different vehicular-based structures (vehicular ad-hoc networks (VANETs), vehicular cloud computing (VCC), and Internet of Vehicles (IoV)). Vehicles generally transmit different road-side data (e.g., traffic, details of nearby vehicles, emergency/environment, location, etc.) from/to another end in a public environment. Hence, three key challenges on data are as follows; (1) secure and effective data storage in the vehicular cloud (VC) (2) efficient data extraction from the VC and (3) reliable data transmission between two entities. Some general methods are to search/store data from/in the cloud, but these techniques are only for data storage and extraction. Next, various communication schemes are proposed for VANETs, VCC, and IoV, but they need high computational resources, and these schemes are vulnerable to multiple security attacks. We find that there is no system, which provides all these data operations (storage, searching, and communication) for vehicle users. In this paper, we propose a dependable system (named as SearchCom) for vehicle applicants to overcome above-mentioned challenges and provide operational facility. The SearchCom is analyzed to verify its security strengths against various security attacks and its performance results in execution time, memory requirement, communication overhead, searching, and energy consumption.
