Ubiquitous service capability modeling and similarity based searching

Abstract

The proliferation of the Internet-of-Things, which is a part of the envisioned future internet, is about to significantly enrich the interactions between people and physical environments, making computing pervasive in our daily lives. To deliver such ubiquitous data as services over the internet, it is essential to describe their capabilities and enable the discovery of the capabilities. However, current service descriptions lack the ability to describe dynamic information, which is crucial for ubiquitous device capabilities. Moreover, they do not provide explicit information on how services are related to each other. In this paper, we propose a capability model for ubiquitous devices (sensors) based on the capability meta-model to describe the dynamics and relevance of sensor services. We also define a generic similarity metric for service capabilities and develop a heuristic searching algorithm based on this metric to find similar sensor services. © 2013 Springer-Verlag.
