Indexer Based Dynamic Web Services Discovery
Clinical Orthopaedics and Related Research(2010)
摘要
Recent advancement in web services plays an important role in business to
business and business to consumer interaction. Discovery mechanism is not only
used to find a suitable service but also provides collaboration between service
providers and consumers by using standard protocols. A static web service
discovery mechanism is not only time consuming but requires continuous human
interaction. This paper proposed an efficient dynamic web services discovery
mechanism that can locate relevant and updated web services from service
registries and repositories with timestamp based on indexing value and
categorization for faster and efficient discovery of service. The proposed
prototype focuses on quality of service issues and introduces concept of local
cache, categorization of services, indexing mechanism, CSP (Constraint
Satisfaction Problem) solver, aging and usage of translator. Performance of
proposed framework is evaluated by implementing the algorithm and correctness
of our method is shown. The results of proposed framework shows greater
performance and accuracy in dynamic discovery mechanism of web services
resolving the existing issues of flexibility, scalability, based on quality of
service, and discovers updated and most relevant services with ease of usage.
