Formalizing and Modeling Fairness for Benefit Distribution in Collaborations

Fairness is not sufficiently formalized to enable the comparison of different fairness requirements. Ad-hoc collaborations in the Internet of Services are driven by trust, and fairness in such collaborations is an expectation that builds trust. We provide formal fairness definitions along with a formal fairness model, which augment collaboration establishment and support building trust. Hence, we are able to reason about fairness and its implications for negotiations.
