Sensor bean: a component platform for sensor-based services

Abstract

Sensor-based services propose to gather, manage, analyze, access and react to sensor data. These services are distributed over heterogeneous platforms. The complexity of the implementation of such services requires software engineering tools to relieve the architect and the developer who are often business experts and not technologies experts. Our proposal relates to the definition of a component model dedicated to the development of SBS, called Sensor Bean. Sensor Bean differs from the usual components models by its service orientation and dynamic architecture and the introduction of data-centric connectors well adapted to measurement flows. This proposal is validated by a prototype coupling OSGi and J2EE and by a first component container for OSGi gateways.
