Survey of Hybrid VANET Design for Provisioning Infotainment Application

Abstract

This paper presents a survey of various existing VANET model for provisioning real-time (i.e. safety critical application) and non-real smart infotainment application for user on the go. Further, it carries out survey of various existing hybrid VANET for provisioning QoS (Quality of services), increase network density using SDN (software defined network), fog computing and cloud computing framework, and future generation high speed wireless network such as LTE (Long term evolution), 5G (Fifth generation), CRAN (Cloud based Radio area network). However, from extensive analysis carried out it can be seen existing hybrid model do not consider feature of each framework/architecture such as VANET communication (i.e. among V2I and V2V), QoS controlling mechanism in SDN for provisioning data from cloud to VANET user and also do not provide efficient resource allocation technique in cloud computing environment to minimize computation cost. This paper shows meeting aforementioned feature in designing hybrid VANET model will aid in offering scalable and flexible smart infotainment application to VANET user. Further, the survey show how propagation model is affected due to environmental factor and presence of obstacle in LOS. Further, discusses about the need for new MAC (Medium access model). Then, discusses about selecting simulation environment/tool to evaluate performance of Hybrid VANET model. Lastly, a novel possible solution is described to overcome research problem which will be the future research direction of this survey. The proposed envisioned model will aid in offering superior performance than existing models.
