Black hole Attack on Wireless Network and Prevention using MANET

A black hole is a security attack in which a malicious node absorbs all data packets by sending fake routing information and drops them without forwarding them. The black hole attack is one such security issue in MANET. Mobile Ad-hoc NETwork (MANET) is an attack occurs due to malicious nodes. We propose an algorithm to detect and prevent black hole attack in AODV routing.
