Anamika: Distributed Service Discovery and Composition for Pervasive Environments

January 1, 2002 - August 1, 2004

Technological advances in semiconductor processing and design as well as wireless networking are leading us towards the vision of Pervasive Computing. We envision that in the (near) future, devices all around a person, either embedded as a part of smart spaces, or being carried by other people in the vicinity, will provide an array of services that she might want to use. Development of customized sxervices by integrating and executing existing ones has received a lot of attention in the last few years with respect to wired, infrastrutcure based web-services. However, service discovery and composition in web-based environments is performed in a centralized manner with the help of a fixed entity. Moreover, wired infrastructure-based service discovery and composition architectures do not take into consideration factors arising from the possible mobility of the service providers. In this project, we are developing a distributed, de-centralized and fault-tolerant design architecture for reactive service composition in pervasive environments. The design of the architecture is based on a peer-to-peer model. We introduce two reactive techniques for service composition in our design.
