RESTful device interaction architecture for embedded devices

Toward ubiquitous network society, there have been challenges to construct smart spaces in living space such as homes and offices by connecting embedded devices with each other; however, many existing smart spaces tend to depend on particular platform or be a self-contained environment. In this paper, we describe requirements on frameworks for smart spaces with embedded devices, and then propose a new framework based on the requirements. The proposed framework is designed to have high scalability and be suitable for cross-platform environments by employing RESTful web service for device interaction architecture. By encoding communication messages for requesting services in x-www-form-urlencoded scheme, the proposed framework can support many kinds of devices including resource-limited devices which can't afford an XML parser. Evaluation with existing frameworks shows the proposed framework is suitable as a framework for smart spaces because of its simple and lightweight architecture.
