A self-organizing P2P framework for collective service discovery

With the advent of the "Internet of Services" and the use of novel technologies such as Software as a Service and Cloud Computing, the market of Information Technology is experiencing an important shift from the request/provisioning of products toward a scenario where everything, computing, storage, applications, is provided as a network-enabled service. When no single service is able to address the requirements of a specific problem, the solution can be the deployment of a workflow composed of several basic services. This paper presents a P2P self-organizing framework that facilitates collective discovery requests, issued to locate all the components of a workflow. The information system is organized so that the descriptors of services that are often used together in the same workflow are placed close to each other. This allows queries to rapidly find several target services, which helps to lower the search time and reduce the computing and network load. (C) 2013 Elsevier Ltd. All rights reserved.
