Protecting AODV Protocol from Black Hole Attacks on WSNs

The emergence of wireless sensor network (WSN) technology is accompanied by intrinsic constraints and vulnerabilities that render it susceptible to malicious exploitation by intruders. The primary objective of this article is to address security issues caused by black hole attacks, which disrupt the proper functioning of the network and may result in data leakage and loss. We provide a control mechanism named “IDSHNAODV” to specifically counteract the effects of malicious nodes by controlling and removing the first Route Reply (RREP) coming from the black hole attack. This strategy will be put into practice and compared with the “HNAODV” protocol using the NS2 simulator. Three performance metrics will be used, along with a quantity of malicious black hole nodes.
