INTRUSION DETECTION IN MOBILE AD HOC NETWORK USING SECURE ROUTING FOR ATTACKER IDENTIFICATION PROTOCOL

In past few decades, the migration of communication takes place from wired networks to wireless networks because of its mobility and scalability and Mobile Ad hoc Network (MANET) is a unique and significant application in recent years which does not necessitates any pre-existing network infrastructure. Each node can act as both transmitters as well as receivers that are communicating with each other when they are in same communication/transmission range. Otherwise, these nodes depend on neighbor nodes to transmit their packets and they possess self-configuring ability which makes MANETs popular in various critical mission applications such as military and other emergency applications. In general, MANETs are open medium network and their nodes are widely distributed which makes the network more vulnerable to various attackers. Some times, the transmitted packets are viewed or modified or corrupted by the attackers through the way to reach destination and the destination could not find such type of packets. So, the receiver can deliver modified packets with wrong information. Thus, it is essential to present an efficient secure routing protocol to preserve MANET from several attacks. In this study, we are going to propose and implement a novel routing protocol named Secure Routing for Attacker Identification (SRAI) protocol that executes at receiver/destination side to discover the modified packets in delivered nodes and generate misbehaviour report to the source. Compared to modern approaches, SRAI protocol establishes higher attacker identification rates in certain considerations.
