IBTM：An incentive-based transaction model by encouraging truthful reporting in the grid market

In the grid market rational and selfish resource providers have strong incentives to deviate from the advertised quality of service(QoS). The current transaction models analyze the trust relationships between providers and users based on historical reports, with insufficient attention to their truthfulness. A new transaction model is proposed to inspirit users to report truthfully and estimate providers service trust, leading users to select resources rationally. Simulation results indicate that the model can effectively regulate the grid market and reduce transaction risk.
