Composite service optimization through decentralized coordination

Service Oriented Computing (SOC) is a computing paradigm that enables the creation of loosely-coupled applications that expose functionality through the offering of services. Composite services are made by the composition of different services and need to maintain certain levels of quality of service (QoS). One type of solution to maintain the quality of service is to effectively select the best component services that will participate in a composition. We show a middle- ware solution that is able to maintain a required QoS, using a decentralized coordination mechanism. This coordination mechanism autonomously adapts in order to improve the overall efficiency of the services being coordinated.status: publishe
