Detecting Route Attraction Attacks in Wireless Networks
Selecting high performance routes in wireless networks requires the exchange of link quality information among nodes. Adversaries can manipulate this functionality by advertising fake qualities for links; by doing so, they can attract routes and subsequently launch pernicious attacks. The authors' measurements suggest that malicious route attraction can fatally impact throughput. They design a framework that is effective against both independent and colluding attackers. In the latter case, they consider both local and remote colluders. With local collusion, malicious nodes exchange and advertise fake routing information to increase the probability of being selected as relays.
