A detailed survey on misbehavior node detection techniques in vehicular ad Hoc networks

Abstract

Communication in Vehicular ad hoc Network relies on exchange of information among different vehicular nodes in the network. This helps to improve the safety, driving efficiency and comfort on the journey for the travellers. In this network, information received from other vehicles is utilized to make majority of the decisions. However, a node may behave malicious or selfish in order to get advantage over other vehicles. A misbehaving node may transmit false alerts, tamper messages, create congestion in the network, drop, delay and duplicate packets. Thus, detecting misbehavior in VANET is very crucial and indispensible as it might have disastrous consequences. This paper presents a detailed survey on some of the important research works proposed on detecting misbehavior and malicious nodes in VANETs. In addition to the details about the techniques used for misbehavior detection, nature of misbehavior, this paper categorizes the schemes for better understanding and also outlines several research scopes to make VANET more reliable and secure.
