QSWSP: QoS Based Scheduled Web Service Positioning

There has been a huge increase in the scale of distributed network service with the rising demand of serviceoriented Architecture (SOA), more and more alternative web services offered by different service providers becomes available over the internet to provide equivalent or similar-function for service user. It is estimated that there would be large number of web services developed, deployed in the internet in next several years. Earlier approaches proposed that two major properties should be taken into consideration that are functional and non-functional (QoS) when user selects services. There are number of different service provider and we have to effectively select the optimal one from web service candidates. In our approach the requests send by the user are scheduled on the basis of Earliest Deadline First. Then by combining the advantages of network coordinate based approach, simple regression, clustering approach and WSP approach, the response time between user and web services can be accurately predicted.
