Semantic-based self-organizing mechanism for service registry and discovery

摘要

Service-oriented computing is the new paradigm for distributed applications. A key issue of utilizing web services is to design a scalable service discovery mechanism. Current discovery method based on centralized registries can easily suffer from performance bottleneck in the service network of large scale. To address such problem, this paper presents a dynamic and scalable mechanism for discovery and registry of semantic web services. Registry proxies are introduced to achieve the data distribution of web service. Behavior of registry proxies are carefully designed to maintain the overall structure in a self-organization way. A distributed balance-aware algorithm is designed to improve the system performance. The result of simulation experiment shows that the proposed mechanism can serve as a scalable solution for semantic web service publication and discovery.
