Abstract

Mobile Ad-hoc Network (MANET) is one of the important research areas. MANET is a cluster of movable nodes that communicate without any wired connection. It refers to a network of moving nodes communicating with other mobile nodes in a multi-hop fashion. Mobile nodes provide flexibility to this network. Thus this flexible network is prone to a variety of attacks. Wormhole attack is a major threat to this network. In this attack, a tunnel is created between two nodes. These nodes transmit all communication through this tunnel. Detecting such attack is a major task. This paper presents a zone-based approach that detects and prevents such attack.
