Fruit Fly Optimization Algorithm for Network-Aware Web Service Composition in the Cloud

Umar SHEHU, Ghazanfar SAFDAR, Gregory EPIPHANIOU
2016 International Journal of Advanced Computer Science and Applications  
Recently, QoS-based web service composition techniques focus on optimizing web service QoS attributes such as cost, response time, execution time, etc.  ...  In doing so, existing approaches do not separate QoS of the network from web service QoS during service composition.  ...  During the composition process, QoS attributes for services are aggregated according to a composition's workflow pattern [2] into a composite service.  ...

2010 IEEE Transactions on Services Computing  
The selection of a Web service, for each activity of the workflow, meeting the user's requirements, is still an important challenge.  ...  One of these is the composition, i.e. the capability to recursively construct a composite Web service as a workflow of other existing Web services, which are developed by different organizations and offer  ...  This study helps in selecting appropriate component WSs for Web service composition. Jaeger et al. [3] propose a mechanism for composite WSs with pattern-based QoS aggregation.  ...
