Abstract

Vehicular Adhoc Network (VANET) is an important and promising research field over the last few years. Vehicles communicate with each other and to the Road Side Units (RSUs) for exchanging the safety and non- safety messages. VANET type of communication is useful in the Intelligent Transportation System (ITS). Despite its advantages, it is extremely vulnerable to various attacks at physical, medium access control, network, and application layers. In this paper, a comprehensive review on the VANET attacks is discussed and we have classified the attacks in VANET into four major categories as follows: (i) False Identity based (ii) Message Disruption based (iii) Monitoring based and (iv) Trust exploitation based. By observing the attack characteristics under the different categories, it is evident that a robust trust and reputation system is imperative to detect the fraudulent messages and the malicious nodes. Therefore, a comprehensive review on trust and reputation systems for VANET is discussed and summarized in the paper. The solutions existing in literature are not suitable for real time due to dynamic nature of VANET. Further, a framework based on trust and reputation system is proposed in this paper to overcome the existing problems of VANET attacks based on the behavior and also mapped every attack to the corresponding layer in the TCP/IP protocol stack.
