Black Hole Attack and Its Counter Measures in AODV Routing Protocol
Mobile Ad-Hoc network is a collection of mobile node. In this network, a wireless node usually moves randomly and dynamically forms a temporary network without a network infrastructure. Due to absence of infrastructure, MANET is used in various application like medical, battle field, business application and remote areas. MANET is vulnerable to attacks such as Black Hole Attack, Grey Hole Attack, and Worm Hole Attack. Wireless Ad-Hoc network may be unprotected against attacks by malicious nodes due to security vulnerabilities. Many mechanisms have been proposed to overcome the Black Hole Attack.
