Internet of Vehicles (IoV) is viewed as a developing worldview for associated vehicles to trade their data with different vehicles utilizing vehicle-to-vehicle (V2V) correspondences by framing a vehicular ad-hoc systems (VANETs), with roadside units utilizing vehicle-to-roadside (V2R) interchanges. Performance of this smart ITS mainly owes to the design of efficient routing protocols in VANETs. Distinct features of VANETs like unsteady connectivity, high mobility and partitioning of the network have made routing of the information in VANETs difficult and challenging, hence dictating the development of efficient routing protocols. The computation of the best route measures the performance of communication whereas routing protocols takes care of communication & routing of the data. Provision of smart communication, necessitates the analysis of routing protocols in VANET. Accordingly in this paper, reviewed various types of existing routing protocols and security approaches in VANET are discussed.
