Implementation of Efficient Cooperative Message Authentication for Vehicular Ad-Hoc Networks

Abstract

Vehicular Ad-Hoc Network(VANET) is a potential area in research field to bestow Intelligent Transportation System (ITS) services to the end users. It is a exigent topic for its high mobility and frequent network distraction. Lately researchers are carrying out task on many specific issues related to VANET like routing, broadcasting, Quality of Service (QoS), security, architectures, applications, protocols, etc. The augment in vehicles in today’s life has lead to brutal road accidents and traffic jam in urban areas. One of the solution to this problem could be a means of communication between the vehicles for safety. Safety measures lack these days in VANET as malicious drivers in the network disrupt the system routine. In this paper , a new location Based Secure Routing Protocol( PBSRP) which is a hybrid of Most Forward within Radius and Border Node based Most Forward within Radius (B-MFR) routing protocols. A module for security is implemented in this protocol using station to station key agreement protocol for preventing system from several attacks. The module goes through three phases: initialization phase, optimal node selection phase and secure data delivery phase. The outcome of Simulation imparts that PBSRP has better performance than MFR in terms of end to end delay and packet delivery ratio when malicious drivers are included in the network.
