Multi-agent coordination for a composite web service

Abstract

The web services composition is one of the most important approaches ensuring to exploit several services by a single, called a composite service. The work presented in this paper proposes a web services composition model in order to reduce the network problems during the composition and reduce the total duration of composition. The proposed model is based on the coordination of software agents by exploiting its characteristics, hence it eliminate the passivity of web technology and make it more responsive. More than this model ensures the execution of various activities to a composite service, by the integration of an execution control strategy which offers solutions at real-time in case to execution problem from one of the composite service activities. Also, the execution control strategy reduces the response time to a web service composition request and reduces the overhead of network traffic.
