IMPACT ANALYSIS OF EPDA AND IPDA ATTACK WITH INCREASING NODE MOBILITY IN DATA COMMUNICATION

Hemant Pareek, Vishal Shrivastva

Abstract: In this Paper, two types of denial of service attacks over mobile ad hoc networks are implemented and their impact is analyzed on data communication process when using a reactive routing protocol for data communication. The reactive routing protocol well known Ad-hoc on-demand distance vector (AODV) routing protocol. In the Implemented attacks, a malicious node i.e., attacker will drop data packets that it receives for forwarding towards the destination of the packet. The attacker can do the attack by either making itself one of the intermediate nodes on the active route. The attackers can be one of the intermediate nodes in two ways. In the first method the attacker is waiting that some route discovery process will select it as one of its intermediate node and then it will drop all the data packets it receives for forwarding to destination. In the second method the attacker uses the dissemination of the false information to become the part of an active route. Due to the wrong information spread by the malicious nodes the routing tables of the source node enters a route for the destination that will surely includes the attacker in the route. The Implemented attack is simulated using a tool Exata and results are drawn using graphs to show the impact of the attack on data communication. Finally, a mechanism is proposed through which both the attack and attackers can be detected during the data communication and can be avoided in further communication process.
