Abstract
As a promising topic of research, Vehicular Cloud (VC) incorporates cloud computing and ad-hoc vehicular network (VANET). In VC, supplier vehicles provide their services to consumer vehicles in real-time. These services have a significant impact on the applications of internet access, storage and data. Due to the high-speed mobility of vehicles, users in consumer vehicles need a mechanism to discover services in their vicinity. Besides this, quality of service varies from one supplier vehicle to another; thus, consumer vehicles attempt to pick out the most appropriate services. In this paper, we propose a novel protocol named RSU-aided Cluster-based Vehicular Clouds protocol (RCVC), which constructs the VC using the Road Side Unit (RSU) directory and Cluster Head (CH) directory to make the resources of supplier vehicles more visible. While clusters of vehicles that move on the same road form a mobile cloud, the remaining vehicles form a different cloud on the road side unit. Furthermore, the consumption operation is achieved via the service selection method, which is managed by the CHs and RSUs based on a mathematical model to select the best services. Simulation results prove the effectiveness of our protocol in terms of service discovery and end-to-end delay, where we achieved service discovery and end-to-end delay of 3 × 10−3 s and 13 × 10−2 s, respectively. Moreover, we carried out an experimental comparison, revealing that the proposed method outperformed several states of the art protocols.
Highlights
In recent times, remarkable advances have been achieved in the field of vehicular Ad Hoc, which help enhancing driving by increasing safety and providing commercial services [1]

We proposed a new protocol that allows building vehicular clouds in an urban area, focusing on Mobile cluster-based vehicular cloud and RSU-based vehicular cloud
Summary
Remarkable advances have been achieved in the field of vehicular Ad Hoc, which help enhancing driving by increasing safety and providing commercial services [1]. All exertions aim to increase the use of Intelligent Transportation Systems (ITS) Due to their restricted range and motion (direction and speed), VANETs are considered as a specific type of Mobile Ad hoc Network (MANET) with a particular mobility. Vehicles and RSUs transmit messages between the source and destination nodes using two types of wireless multi-hop transmission, which are InterVehicle Communication (IVC) and Vehicle-to-Roadside Communication (VRC) It is worth mentioning the efforts of the automotive industry that developed the Dedicated Short-Range Communication (DSRC) technology, which enables high-speed direct communication between vehicles and the surrounding infrastructure. Our RCVC enables RSU and CH to act as repositories aiming to help consumer vehicles (CV) to access and find resources that are offered by supplier vehicles (SV) on VC in an urban environment.
