As the number of Internet of Vehicle (IOV) users is increasing the demand for retrieving the precision and efficient services as per the vehicle user’s requirements also increases. As the VANET milieu is highly dynamic and topology changes occur recurrently, retrieving service with accuracy and efficiency is the decisive issue.
