Coordinating one-to-many concurrent negotiation for service provision

In Service-Oriented Architecture (SOA), a consumer may require a service which can be offered by several providers with the same functionality but different Quality of Services (QoS), such as price, response time, reliability, and data quality. The consumer can negotiate with all of these providers simultaneously to reach an agreement on the QoS with one provider - this is referred to as one-to-many concurrent negotiation model. Most existing studies on one-to-many concurrent negotiation adopt the concession function from one-to-one bilateral negotiation, which determines the utility level the consumer is going to concede to for each provider individually. This makes it impossible to adjust the concessions based on the negotiation with other opponents in the context of one-to-many negotiation. In our work, we propose a novel concession strategy that coordinates the multiple concurrent negotiation threads. Simulation experiments are conducted to demonstrate the effectiveness of our proposed approach. © (2013) by the AIS/ICIS Administrative Office All rights reserved.
