SQTrust: Social and QoS Trust Management and Its Application to Mission-Oriented Mobile Groups

Abstract

We propose to combine the notion of social trust derived from social networks with that of quality-of-service (QoS) trust derived from 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 develop a novel model-based approach to identify the best protocol setting under which peer-to-peer subjective trust as a result of executing our distributed trust management protocol is accurate with respect to ground truth status over a wide range of operational and environment conditions with high resiliency to malicious attacks and misbehaving nodes. Furthermore, using mission-oriented mobile groups as an application, we identify the best trust formation model under which the application performance in terms of the system reliability of mission-oriented mobile groups in MANET environments is maximized.
