Performance analysis of black-hole attack mitigation protocols under gray-hole attacks in MANET - 2017

Research Area:  Mobile Ad Hoc Networks


The recent development in wireless communication technology and portable devices has led to the development of Mobile Ad-Hoc Network which has unique features such as dynamic topology, open wireless medium, decentralized system etc but these network are susceptible to various denial of service attacks such as black hole, gray-hole, worm hole etc. In order to mitigate black-hole attack, various protocols have been proposed but these protocols have been not analyzed under gray-hole attack. In this paper, we have made classification of denial of service attack and highlighted the key differences among black hole, sequence number based gray-hole and smart gray-hole attack. We simulated two types of attacks namely Attack1 and Attack2 by modifying AODV protocol. The Attack1 (GAODV) is sequence number based gray-hole attack protocol whereas Attack2 (SGAODV) is smart gray-hole attack protocol. In order to observe the impact of gray-hole attacks on AODV, IDS-AODV and MBDP-AODV, NS-2.35 simulator is used. The simulation results show that MBDP-AODV performs well as compared with IDS-AODV and AODV under sequence number based gray-hole attack. Through simulation, it has also been found that the impact of the smart gray-hole attack is low as compared with the sequence number based gray-hole attack.
