PMDS: A Probabilistic Misbehavior Detection Scheme in DTN

Malicious and selfish behaviors represent a serious threat against routing in Delay or Disruption Tolerant Networks (DTNs). Due to the unique network characteristics, designing a misbehavior detection scheme in DTN represents a great challenge. In this paper, the authors propose PMDS, a probabilistic misbehavior detection scheme, for secure DTN routing. The basic idea of PMDS is introducing a periodically available Trusted Authority (TA), which judges the node's behavior based on the collected routing evidences. They model PMDS as the Inspection Game and use game theoretical analysis to demonstrate that, by setting an appropriate investigation probability, TA could ensure the security of DTN routing at a reduced cost.
