A Survey On Various Methods In VANET Based On Security And Privacy-Preserving Navigation System

Vehicular ad hoc network (VANETs) is a promising and challenging approach to improve the traffic management and traffic safety with wireless vehicle-to-roadside and vehicle-to-vehicle communications. An efficient navigation scheme is employed based on the online road information gathered by VANETs to direct the drivers to corresponding destinations in a real-time and distributed manner. Major advantage of using real-time road situation is to estimate a better route and the information source that is appropriately authenticated simultaneously. In order to guard the privacy of the drivers, the destination and the driver who provides the query are assured to be unlinkable to any party. This idea can be attained by enhancing the anonymous credential. In this paper, various methods related to security and privacy related methods are surveyed for providing security for VANET. Each surveyed method briefly discusses the security and privacy related issues and solutions in VANET. At last, comparative measures of each method are presented which provides the significance and limitations for VANET Based Secure and Privacy-Preserving Navigation system.
