INFRASTRUCTURE BASED POSITION VERIFICATION TECHNIQUE FOR VANETs

Abstract

VANET has been an interesting research area for years. It is a technology that uses moving cars as the nodes to create a mobile network. VANET comprises of two types of communications, V2I and V2V, accompanied by wireless communication technology, particularly IEEE 802.11p. This technology has been developed to improve road safety and to make road traffic more manageable. A lot of research has been done to make the transportation intelligent but security aspect of VANETs got less concern. As in VANET human lives are directly involved thus it becomes necessary to pay close attention to the VANET security issues. One of the most important security issues is related to the forged position of a vehicle at any time in the vehicular network. There are various applications whose working depends upon the accuracy of position information. Thus, addressing this issue is of prime importance. In this thesis, an infrastructure based algorithm has been proposed to address position faking issue in VANETs. Its performance has been compared with one of existing infrastructure-less algorithm.
