摘要：Vehicular Ad hoc Networks are an important subset of MANETs. VANET is the group of vehicles that are connected to each other wirelessly. VANET security is a major issue that is being worked upon these days. One tiny security flaw can cause a huge loss of lives. For ensuring the security, Intrusion Detection Systems (IDS) are implemented in VANETs for detecting any intrusion. The IDS analyzes the network and detects any malicious node if present. This paper presents a comprehensive review of some of the recent and important intrusion detection research works and presents a comparative analysis of the techniques used in detecting intrusions as well as attacks focused.
