ABSTRACT
Without a fixed security infrastructure, mobile ad hoc networks must distribute intrusion detection among their nodes. But even though a distributed intrusion detection system can combine data from multiple nodes to estimate the likelihood of an intrusion, the observing nodes might not be reliable. The Dempster-Shafer theory of evidence is well suited for this type of problem because it reflects uncertainty. Moreover, Dempster?s rule for combination gives a numerical procedure for fusing together multiple pieces of evidence from unreliable observers. The authors review the Dempster-Shafer theory in the context of distributed intrusion detection and demonstrate the theory?s usefulness.
