A mobile ad hoc network (MANET) contains a collection of wireless mobile nodes that forms a temporary network without having any fixed infrastructure or centralized administration. MANET is assailable to routing misbehaviour. We are worried of an especially severe security attack that affects the MANET routing protocols, it is called the wormhole attack. During the attack an attacker captures packets from one location in the network, and tunnels them to other attacker at a distant point, which replays them locally. In this paper, we examine briefly the behavior of various Denial-of-Service attacks at the network layer of MANET and provide comprehensive survey of on wormhole attack and introduce the existing defense approaches to these attacks.
