Performance Evaluation of AODV Routing Protocol Using Different Parameters Under Black Hole Attack

The major challenging issue in mobile ad hoc networks is denial-of-service (DoS) attacks which disrupt the normal behaviour of routing protocols. DoS attacks are more effective attacks which result in degradation of routing protocol performance. These attacks occur in the communication network and degrade performance by delaying more packets and less throughput. In this paper, the black hole attack is introduced and the performance analysis of the AODV routing protocol is carried out with and without black hole attack under different traffic conditions with different packet sizes using different parameters. The traffic conditions used in this paper are CBR and FTP which are based on TCP and UDP agents. The instantaneous delay, throughput, and normalized routing load are common measure parameters used to carry out the performance analysis of the AODV routing protocol with and without black hole attack.
