Trust Management for Mobile Ad Hoc Networks and Its Application to Mission Oriented Mobile Groups

Start Date: 11/15/2009
End Date: 08/14/2012

We propose to combine the notions of social trust derived from cognitive and social networks with quality-of-service (QoS) trust derived from information and communication networks to obtain a composite trust metric as a basis for evaluating trust of mobile nodes in mobile ad hoc network (MANET) environments. We demonstrate the effectiveness of the composite social and QoS trust management protocol (henceforward referred to as SQTrust) by trust management of group communication systems with intrusion detection capability in MANETs for critical mission executions. SQTrust is designed to satisfy desirable trust properties in MANETs including subjectivity, incomplete transitivity, dynamicity, asymmetry and context-dependency. It is distributed in nature and will be run by each mobile node to subjectively yet informatively assess the trust levels of other mobile nodes nearby or distance away, with or without prior interactions, through the use of recommenders. The node-to-node subjective trust evaluation, T_ij (t), once proven to be close to objective trust evaluation, will be useful in Naval combat situations.
