Abstract
A Mobile Ad-hoc Network (MANET) is a dynamic wireless network that can be formulated without the need for any pre-existing infrastructure in which each node can act as a router. One of the main challenges of MANET is the design of robust routing protocol that adapt to the frequent and randomly changing network topology. A variety of routing protocols have been proposed and most of them have been extensively simulated or implemented as well. Several attacks are possible in the available routing protocols such as Wormhole attack, black hole attack, byzantine attack, etc. Among these attacks black hole attack is of major concern in AODV, is one of the popular routing protocols for MANET. Due to security vulnerabilities of the AODV routing protocol, wireless ad-hoc networks are unprotected to attacks of the malicious nodes. One of these attacks is the Black Hole Attack. In this study, analyzed the use of AOMDV (Ad-hoc On-demand Multipath Distance Vector) and improved the security of MANET against the black hole attack. The main objective is to provide security against the Black hole attack.
