Comparative Analysis of Black Hole Attack Solutions in AODV Protocol

A mobile ad-hoc network (MANET) is an autonomous wireless network which consists of mobile nodes that communicate with each other over multi-hop wireless links. Due to the absence of any fixed infrastructure, MANETs are unprotected to various types of security attacks. Black hole is one of these attacks and a malicious node announces the freshest and shortest path to a destination node and then drops all data packets that subsequently go through it. Many researchers have proposed different techniques for preventing and detecting this attack. In this paper, we have surveyed and discussed the existing solutions to black hole attacks on AODV protocol.
