Abstract

Mobile means moving and ad hoc means temporary without any fixed infrastructure. Hence, mobile ad hoc network is a temporary network in which nodes are moving without any fixed infrastructure or centralized administration. MANETs are vulnerable to security attacks because of the decentralized authentication. Black hole, gray hole, worm hole, flooding are such type of security threats that affects the network. This paper presents a review on MANET, AODV routing protocol, flooding attack and comparison of various detection and prevention techniques of flooding attack. Among all this techniques, RFAP technique can easily find the attacker node and protect the network from RREQ flooding attack.
