Variable control chart for detecting black hole attack in vehicular ad-hoc networks

The nature of VANET networks makes the network vulnerable to several attacks such as the black hole attack which is part of Denial of Service attacks (DOS). The aim of these attacks is to prohibit users from using one or more services by making the communication unavailable. In this sense and during the routing process, the malicious node tries to acquire the route by forging routing information in order to receive the data and then drops it without transferring it to its destination. In this paper, we propose a novel detection method of such attack during communication in a VANET network. This method is based on a variable control chart which is widely used in the industrial field to monitor the quality of a given process. This method can identify malicious nodes in real time by deploying the monitoring system in each receiving node within the network. Our method is easy to implement and does not require any modification to the 802.11p standard or the routing protocol as we will demonstrate by NS-2 simulations and SUMO microscopic and continuous road traffic simulator using a real map.
