VANETs have developed as one of the largest potential topics in the field of automotive industries with promising and challenging futures in various aspects. VANETs permit intelligent vehicles to generate their own organized network without the need of the stable network. In this paper we introduce VANETs and its comparison with MANETs, standard wireless access in VANETs like WAVE model partly based on OSI model. We present a comprehensive study on routing protocol in VANETs like position-based routing, Geo-Cast based routing, etc. and scheduling in VANETs like deadline-based scheduling, hybrid-based scheduling, etc. This paper presents open research issues in VANETs highlighting challenges like security and privacy issues, network congestion control issues, etc, numerous routing and scheduling issues in VANETs.

Privacy Issues

In vehicular ad hoc networks (VANETs), conditional privacy preserving authentication (CPPA) scheme is widely deployed to solve security and privacy issues. Existing CPPA schemes usually require ideal tamper-proof devices (TPDs) on vehicles which, however, might be infeasible or do not exist in reality due to high security requirements. To address this problem, we propose a practical framework of CPPA scheme that supports more realistic TPDs which are less secure correspondingly. We demonstrate that this framework also manages to achieve nonframeability in addition to other security objectives including nonrepudiation, conditional privacy preserving, and unlinkability. Moreover, performance analysis shows that our framework has better efficiency in authentication. All these features make our framework practical for VANETs.

Privacy Issues

Vehicles in a vehicular ad-hoc network (VANET) broadcast information about the driving environment in the road. Due to the open-access environment, this means that the VANET is susceptible to security and privacy issues. However, none of the related works satisfies all security and privacy requirements. Besides, their proposed has huge overhead in terms of computation and communication. The present paper is a provide a thorough background on VANETs and their entities; different security attacks; and all requirements of the privacy and security for VANETs. This paper may serve as a guide and reference for VANETs in the design and implementation of any new techniques for protection and privacy.

Hoc Networks

Vehicular Ad-Hoc Networks (VANETs), a new mobile ad-hoc network technology (MANET), are currently receiving increased attention from manufacturers and researchers. They consist of several mobile vehicles (intelligent vehicles) that can communicate with each other (inter-vehicle communication) or with fixed road equipment (vehicle-infrastructure communication) adopting new wireless communication technologies. The objective of these networks is to improve road safety by warning motorists of any event on the road (accidents, hazards, possible deviations, etc.), and make the time spent on the road more pleasant and less boring (applications deployed to ensure the comfort of the passengers). Practically, VANETs are designed to support the development of Intelligent Transportation Systems (ITS). The latter are seen as one of the technical solutions to transport challenges. This chapter, given the importance of road safety in the majority of developed countries, presents a comprehensive study on the VANET networks, highlighting their main features.
