dc.description.abstract | In service oriented scenarios, applications are created by composing atomic services and exposing the resulting added
value logic as a service. When several alternative service providers are available for composition, quality of service
(QoS) properties such as execution time, cost, or availability are taken into account to make the choice, leading to the
creation of QoS-aware composite web services. Finding the set of service providers that result in the best QoS is a NPhard
optimization problem. This paper presents QoS-Gasp, a metaheuristic algorithm for performing QoS-aware web
service composition at runtime. QoS-Gasp is an hybrid approach that combines GRASP with Path Relinking. For the
evaluation of our approach we compared it with related metaheuristic algorithms found in the literature. Experiments
show that when results must be available in seconds, QoS-Gasp improves the results of previous proposals up to
40%. Beside this, QoS-Gasp found better solutions than any of the compared techniques in a 92% of the runs when
results must be available in 100ms; i.e. it provides compositions with a better QoS, implying cost savings, increased
availability and reduced execution times for the end-user. | eng |
