Efficient Attacker Node(s) Detection and Isolation Schemes in MANETs OLSR Protocol

Abstract

© 2022 IEEE.Intrusions can be imposed from different directions in network environments. Particularly on Mobile adhoc Networks (MANETs), it is more frequent as the nature of this network is exposed it to be attacked. This happens due to the lack of defined infrastructure paths, no defined perimeters, and the communication medium used is not trusted. In this paper, we design and implement an OLSR protocol used with an Intrusion Detection System (IDS) mechanism that accurately detects misbehavior node(s) using few additional messages on the existing messages on the transmission path. It validates the path and attacker detection message which isolates the attacker using an alternative path for End-to-End (E2E) communication between the source and the destination nodes in a typical MANET.
