A Secure Mechanism for Content Distribution in Vehicular Ad-hoc Networks

Neeraja R | M. Jebakumari

Abstract: Content distribution through roadside Access Points (APs) has become indispensable for vehicular users to obtain good road safety. Cooperative Content Distribution System for Vehicles (CCDSV) operates upon a network of infrastructure APs to distribute contents to moving vehicles collaboratively. In this paper, a Cooperative Content Distribution System for Vehicles using cooperative APs in a hybrid structure called the contact map, that takes advantage of the roadside units ( RSUs) that are connected to the Internet and providing various types of information to VANET users, is introduced. A new LMS (Live Multimedia Streaming) scheme using Symbol-level network coding (SLNC) mechanism to secure the system is also included.
