End-to-end authentication based secure communication in vehicular ad hoc networks (VANET)

Abstract

Wireless channels are used to link vehicles in a VANET. In these networks, there is no fixed or static base station or any other kind of infrastructure support. An ad hoc network for mobile devices enables them to connect to each other without the need for a central hub. There are nodes in these networks which are Vehicles, and they may travel independently of each other in terms of location. Even if two mobile nodes aren’t within radio range of one another, a message may still be sent between them through an intermediary node in a VANET. The difficulty of maintaining routes makes VANET’s routing system a top priority. Ad hoc vehicular networking is becoming more important as utility applications become more popular. There is no reason why ad hoc networking can’t be used when there is a lack of or cumbersome access to an existing communication infrastructure. This network is susceptible due to the fact that its nodes are on the move. There is the potential for a wide range of assaults. When a network node acts maliciously and must discard the whole incoming packet, we will examine how well the AODV protocol performs. Analysis of performance measures such as PDF, AED, NRL, TCP/IP throughput and packet loss in relation to different node counts, pause times and send rates will be performed. A countermeasure to detect the rogue node will also be suggested. The NS-2 simulator will be used to carry out the simulations in question.
