Towards a Human Trust Model for Mobile Ad-hoc Networks

stence of a central specification server where trust information is stored and used. The framework must be highly customisable, in order to capture the varying and complex natural disposition of an individual to trust into computer models; this should be achieved without causing disruption to the device computation and communication resources. Approaches such as [2] work well at the routing level, where trust decisions are automatic and homogeneous, but su#er severe limitations at the application level, where subjectivity in the decision making process becomes fundamental. Other approaches (e.g., [5]) deal with trust in a less automatic fashion, but they still fail to capture a variety of aspects peculiar to human trust (e.g., ways to recover from a bad reputation, natural disposition to trust unknown entities, etc.). Finally, a trust decision framework for mobile ad-hoc networks must be selfish: in a resource constrained environment, selfishness is likely to prevail over cooperation
