Denial of Service Attacks Implementation and Detection Approach for MANET

Abstract: This paper implement and analyze two most common very effective Denial of service attacks known as Explicit packet dropping attack (EPDA) and implicit packet dropping attack (IPDA). The effects of both of these attacks are measured during data communication through a reactive MANET routing called Ad-hoc on-demand distance vector routing protocol (AODV). In Explicit packet dropping attack (EPDA), the attacker first explicitly gain access over the newly establish route between a source destination pair during the route discovery process and then drop all the packets that goes through it. On the other hand, in case of the implicit packet dropping attack (IPDA) the attacker does not know that at what time during the data communication process and of which data flow it is going to attack. Therefore the attacker implicitly caught on some data communication route and once it is on the route it will drop all the data packets that it receives for forwarding towards the destination node. To prove the effectiveness and correctness of the attacks and their detection methods, compare simulation results for various metrics over various MANET scenarios.
