Security Analysis of Vanet (Vehicular ad-hoc Network)

Abstract

VANET is a network in which cars or any other vehicles are used as mobile nodes. These mobile are used to form a communication network and these cars can move freely in any direction. VANET is a wireless network which is used for data exchange. As the VANET network name suggests, it is performed in vehicles. VANET consists of vehicle-to-vehicle (V2V) and vehicle - to - infrastructure (V2I) communications supported by wireless access technologies. In VANET, routing protocols have most significant role in terms of performance. The way of sending and receiving the packets is determined by routing protocols. In this paper , we examine and analyze the performance of Ad-hoc On-Demand (AODV) , Destination-Sequenced Distance Vector (DSDV) , Dynamic Source Routing (DSR) routing protocols over Constant Bit Rate (CBR) by using different speeds and number of nodes. VANET wireless communication is used to improve road safety and traffic efficiency. The performance measurements : Packet Delivery Ratio and Average Throughput, Average End to End Delay are examined with respect to speed and number of nodes. The objective of this study is to find the best routing protocol for security purpose so that it can be further used. Based on our validated results , AODV performs the best among from all three protocols.
