WormHole Attack in MANET
Networking , Technology & Science / August 19, 2017

A wireless ad-hoc network is temporarily set network by wireless mobile computers moving arbitrary in the place that have no fixed infrastructure and all of the transmission links are established through wireless medium. MANETs are a kind of wireless ad-hoc network. Each node in a MANET is free to move independently in any direction leads to changing its links to other nodes frequently. Each node operates as an end system and also as a router to forward packets. The primary challenge in building a MANET is equipping each node to continuously maintain the information required to properly route traffic. Wireless ad-hoc network is promising in solving many challenging real-world problems like military field operation, communication in emergency response system and oil drilling and mining operation. Wireless mobile ad-hoc networks are vulnerable to many security attacks because of shared channel, insecure operating environment, lack of central authority, limited resource availability, dynamically changing network topology, resource constraints. MANET’s open issues are like security problem, finite transmission bandwidth, abusive broadcasting messages, reliable data delivery, dynamic link establishment and restricted hardware caused processing capabilities emerges into new horizon of different research areas. Wormhole Attack In MANETs, each node communicates directly with its neighboring nodes…
