Abstract

Optimal web service selection among number of services for diversified user’s functional requirements brings a challenging issue. Currently available service selection schemes consider the quality of service (QoS) parameters of web services. These schemes produce less significant results when there are multiple service providers with their multiple functionally identical services. Present paper describes a QoS-aware optimal selection scheme. The paper considers an additional QoS parameter called trust rate for each service provider. A trust rate depends on the reliability of the service provider. The paper describes a binary search algorithm, which selects the trustworthy services. This study discusses results of computational time complexity for searching optimal services. The QoS-aware selection is optimized based on trust rates. Advanced Java development environment Eclipse is used for the implementation. Axis2 server is used to create the web services. A comparative study of results with the complexity computed for the earlier adopted schemes shows that complexity decreases exponentially. The proposed scheme is experimented on e-supply chain management system. Along with trust rate, some extended parameters can be evaluated to achieve optimization.
