Trust-Based Intrusion Detection for Multi Path OLSR Protocol.

In this paper, we have focused on the implementation of a mechanism for detecting malicious nodes in the MP-OLSR routing protocol through the integration of trust reasoning. The study carried out has enabled the emergence of trust rules between nodes based on local information and messages exchanged during the neighborhood discovery process and network topology to make the MP-OLSR protocol more trusted. The correlation between the received control messages allows nodes to validate the neighborhood at one hop and two hops. When the information received is consistent with the MP-OLSR protocol specifications, this reasoning allows the creation of a trust relationship. Otherwise, it allows nodes to be wary of the sources of its inconsistencies. When an attack is detected, the countermeasure proposed allows the attacking node to be isolated from the network and to guarantee its non-participation in the routing mechanism by simply integrating this node in the HELLO message with a modified Link Code, so that it is declared by all the nodes of the network as an attacker.
