The successful integration of the Service Oriented Architecture (SOA) in large distributed environments greatly depends on their support of quality of service (QoS) management. The aim of QoS management is to guarantee diverse QoS levels to users issuing requests from a variety of platforms and underlying networks. In this paper, we present our policy-based framework for QoS management in SOA environment with both usual and mobile users. The framework is based on a federation of QoS Brokers that are in charge of mediating between service requestors and service providers, and carrying out various QoS management operations. We describe an auction-based ranking algorithm of functionally equivalent services, which ranks services according to their ability to fulfill the service requestor QoS requirements. The brokers are also in charge of handling appropriately service requests from mobile users equipped with various handheld devices.
