Mobile ad hoc network is a network that is organized by itself, adaptive in nature and on an ad hoc basis. As a results of decentralized infrastructure several security problems are arise and malicious activity performed by offender. MANET routing disrupts if participating node do not perform its intended function and start performing malicious activity. A specific attack called wormhole attack basically include two malicious nodes and it enables an attacker node to record packets at one location in the network, tunnels them to another location and retransmits them into the network. In this paper, various types of MANET routing protocols, variants of wormhole attack and also the countermeasures on wormholes along with future trends have been discussed in detail.
