Commitment-aware reputation system for the digital marketplace

The digital marketplace (DMP) connects mobile users to network service providers, who bid to provide connectivity on a per-call basis. To operate successfully, the DMP must allow users to differentiate between network providers based on past reliability. DMP contracts include an agreed commitment level, to allow providers to offer varying quality-of-service levels. A new reputation system is presented, which scores network providers according to how well they meet commitments. Simulation results show that the reputation function is fair, responsive, and stable.
