Abstract
The performance of mobile ad hoc network transmissions subject to disruption, loss, interference, and jamming can be significantly improved with the use of network coding (NC). Focusing on the Optimized Link State Routing (OLSR) protocol, an IDS mechanism to accurately detect and isolate misbehaviour node(s) in OLSR protocol based on End-to-End (E2E) communication between the source and the destination is proposed. The collaboration of a group of neighbour nodes is used to make accurate decisions. Creating and broadcasting attackers list to neighbour nodes enables other node to isolate misbehaviour nodes by eliminating them from the routing table. Eliminating misbehaviour node allows the source to select another trusted path to its destination. The simulation results show that the proposed mechanism is able to detect any number of attackers while keeping a reasonably low overhead in terms of network traffic.
