Design and Analysis of Secure VANET Framework preventing Black Hole and Gray Hole Attack
Abstract
Vehicular Networks are considered as novel class of wireless networks, also called as VANET (Vehicular ad-hoc Networks). It is a key component of Intelligent Transport System (ITS). VANET technology is identified for improving road safety and transport efficiency. However, due to recent arise in security issues in VANET, VANETs must have a secure way for communication which is quite challenging and vital issue. This paper scrutinized the effects of packet loss in the network due to Black Hole and Gray Hole attacks and also propositions a detection technique that competently detects both attacks in the network. In this research paper simulation is completed by using NS-2 simulator. In this research work the attack is performed and detected on AODV routing protocol. Furthermore, to determine the effects on attacks on network performance simulation is performed on different network scenarios.
