A Scalable Grid and Service-Oriented Middleware for Distributed Heterogeneous Data and System Integration in Context-Awareness Oriented Domains

This chapter investigates the application of SOA principles for integrating embedded devices features, typically operating in ubiquitous computing environments, with enterprise-level services and business processes. Under this perspective, we present the SAI – Service Application Integration – system as a working example of a message-oriented middleware supporting context-aware application development. A special case study, focused on the monitoring of dangerous goods shipment via maritime transport and involving the gathering, processing, and distribution of data collected by heterogeneous components, has been designed to experiment the added value of the proposed integration system in a Web of Things scenario.
