Mobile Ad hoc NETworks (MANETs) has become one of the most prevalent areas of research in the recent years because of the challenges it pose to the related protocols. MANET is an infrastructure less network with mobile nodes. Due to mobility provided to the node i.e. dynamicity of the network the network is prone to various attacks. This paper describes various attacks and specially focuses on the wormhole attack and its variants. The paper also describes the AODV routing protocol with its packet format. The paper also describes how wormhole attacks works in AODV.
