Abstract:
Vehicular ad hoc networks are types of mobile ad hoc networks in which each automobile acts as an intelligent node and can have links to other automobiles and with equipments that are beside the road. The main difference between vehicular ad hoc networks and mobile ad hoc networks are in terms of higher speed of their components, extent, span and scale. One of the main concerns about designing vehicular ad hoc networks is users' security and protection of their privacy policy. Althoug a lot of protocols have been suggested for improvement of securities in these networks up to now, many research challenges regarding users' security and their privacy have been left and need to be considered and resolved. In this thesis, we have discussed about presented protocols for improvement of security in VANETs and cosidering their advantages and disadvantages. We have introduced a protocol as a suggestive solution for improvement of authenticationand protection of user privacy. In addition to protecting privacy, this protocol also effectively authenticates users by corporation of nodes, and as a result extremely reduces packet loss rate
