The first one is to use a function of the trust value of a peer as its credibility factor recursively so feedback from trustworthy peers are considered more credible and thus weighted more than those from untrustworthy peers. We refer to the basic trust metric that uses the Trust Value of a peer recursively as its credibility Measure as PeerTrust TVM metric and it is defined as follows: I (u ) T (u ) = ∑ S (u, i) * T ( p(u, i)) i =1 I (u ) ∑ T ( p(u, i)) i =1 This solution is based on two assumptions.
