Time Series Prediction QoS Routing In Software Defined Vehicular Ad-hoc Network

Vehicular ad hoc network (VANET) is a valuable and important wireless ad-hoc network which uses advanced wireless technologies. It has become most popular in this digital world of Internet Of Things(IOT) because of it wide verity of applications such as e-commerce on the fly in vehicles, sharing multimedia contents such as audio, video, playing games, multihop dissemination of emergency messages to other vehicles, accesing internet and cloud services on the move. However VANET suffer many challenges such as link failure because of high mobility of vehicles, and also current VANET architecture is not flexible for the wide range of IOT and cloud computing applications. Recently Ian Ku, You Lu, Mario Gerla et. al proposed a new architecture for VANET based on software Defined Networks (SDNs) and they discussed various new services and applications that can be supported by the new architecture. They proposed a new routing protocol for VANETS using SDN and compared with existing MANET/VANET protocols and showed better performance. In this paper we show that their protocol still suffers some problems in certain scenario which results performance degradation and an improved routing protocol is proposed and analyzed with better performance.
