Boundary Payoff Determination Approach for Time-Sensitive Services to Select Providers Online

Service users in Service Oriented Architecture (SOA) need to choose provider from the candidates that respond their service requests in succession. For time-sensitive services, the user has to decide the optimal time to stop waiting for the next coming providers in order to shorten the total time. The Boundary Payoff Determination (BPD) approach is proposed in the paper to help the users to predict the payoff of each coming providers, and equips the users with practical conditions and steps to make proper decision. Simulation experiments show BPD superior to the existed methods and able to increase the QoS level of time-sensitive services in SOA.
