SECURITY IN VEHICULAR AD HOC NETWORK BASED ON INTRUSION DETECTION SYSTEM

Implementation of mobile ad hoc networks has eventually captured practically most of the parts of day-to-day life. One variation of such networks represents the Vehicular Ad Hoc Networks (VANETs), widely implemented in order to control day-to-day road traffic. The major concern of VANETs is oriented around providing security to moving vehicles that makes it possible to reduce accidents and traffic jam and moreover to establish communication among different vehicles. In this study, we analyze a number of possible attacks that may pertain to VANETs. Intrusion detection imposes various challenges to efficient implementation of VANETs. To overcome it, several intrusion detection measures have been proposed. The Watchdog technique is one of them. We detail this technique so as to make it convenient to implement it in our future investigations.
