On the prevention of collusion attack in OLSR-based mobile ad hoc networks

MN Kishore Babu Antony Franklin C Siva Ram Murthy
Abstract: A particularly severe attack on routing protocols in Mobile Ad hoc Networks (MANETs) is the collusion attack, in which a pair of colluding attackers prevent routes to a specific node (targeted node) from being established. This attack has devastating impact on Optimized Link State Routing (OLSR) protocol which is one of the standard routing protocols for MANETs. When there is a collusion attack in the network, the simulation results show that the Packet Delivery Ratio (PDR) drops to 0% for the targeted node. In this paper, we ...
