In our day-to-day life due to the usage of more number of vehicles there arises an increasing demand and a big challenge to control the traffic in Vehicular Ad-hoc Network (VANET) which is considered to be a major environmental concern. Generally, the traffic alert information is imparted to vehicles as V2V (Vehicle-to-Vehicle) or V2I (Vehicle-to-Infrastructure) communication medium. The VANET is effectively a subset of MANET (Mobile Adhoc Network). It is a self-forming network which can function without any centralized control. This paper mainly concentrates on enhancing the efficiency, performance and confidentiality in transferring the traffic alert messages ensuring that the data integrity is not lost. In the existing system, the entire information (like vehicle id, location, and position) are transmitted together to other vehicles which leads to major attacks and thereby the confidentiality of the system is compromised (like tracking of vehicles etc). VAMD (VANET-based Ambient Message Dissemination) scheme is thereby proposed so as to support secured dissemination of traffic messages and to filter only the traffic alert messages. SP (Service Provider) is introduced in addition to RSU (Road Side Unit) to deliver the value added services to ongoing vehicles only on demand. It also helps for an efficient, secure, and privacy-preserving algorithm to smoothen the progress of vehicular node participation. In addition, it increases the number of forwarders to participate in the message dissemination.
