A Web Services-oriented Architecture for Integrating Small Programmable Objects in the Web of Things

In this work, we present a concrete framework, based on web services-oriented architecture, for integrating small programmable objects in the web of things. Functionality and data gathered by the Small Programmable Objects (SPO) are exposed using Web Services. Based on this, by exploiting XML encoding, SPO can be comprehensible by any web application. The architecture proposed is focused in providing secure and efficient interoperability between SPO and the web. Additionally, the proposed architecture provides management capabilities for deploying, maintaining and operating SPO applications across multiple networks. We present the multilayer architecture of our system and its implementation, which uses a combination of Java Standard and Micro Editions. Finally, we present a case study presenting our implementation. In this application we use SunSPOTs, which are wireless network motes developed by Sun Microsystems.
