摘要：Vehicular ad hoc technology is a subset of mobile networks (MANETS) where vehicles are considered to be nodes communicating. A network of moving vehicles is established for a specific need or situation. Security has become an indispensable matter of attention in the Vehicular Ad-Hoc Network (VANETS), which is vulnerable to many security threats. One of the security threats is the Denial of Service (DoS) attacks, where a malicious node forges a large number of fake identities .To guarantee this security, network availability is inevitable. The network availability enhances node to node communication. The network is prone to many security challenges. The Denial of Service attack (DOS) on the VANETS is among the most venomous attacks on the network. DOS attacks aims at degrading the availability and quality of the network, in this case the attackers can potentially flood entire network so that no one will be able to use the applications/services and prevent the legitimate nodes from accessing services or resources such situations can create catastrophic sit uations if triggered. This paper aims at providing a review and discussions of the DOS detection and prevention mechanisms, moreover it intended to propose the PSO algorithm used to detect and prevent DOS in VANETS. Despite the many efforts towards prevention of the DOS attacks, it still remains a major concern. In this paper various methods of prevention and detection are discussed and a more reliable method has been presented.
