An Approach to QoS based Selection and Composition of Semantic Web Services based upon Multi-Agent Negotiation

This paper presents a QoS (Quality of Service) based selection and composition model for semantic web services in which the negotiation is performed with all the discovered service providers and the negotiation results are used in the selection process. In semantic web service composition, the selection can also be performed after negotiating with all the discovered service providers and the negotiation-agreements generated from the negotiation can also be used in the selection process. This paper presents a semantic web service selection and composition model based upon this concept. In this paper, a multi-agent negotiation based semantic web service composition approach has been presented. A negotiation agreement based selection model has also been presented that uses the assessment of the various quality parameters included in the negotiation agreement for rating the service provider agents. The implementation issues in the work has been discussed and the comparative analysis has been performed.
