Sensor Web 2.0 as a Service for Internet of Things

Abstract

The Internet of Things (IoT) is a new paradigm that various objects associated with sensors are connected to Internet. The IoT can enable real-world devices to offer their functionality via Internet, but it has no mechanism to facilitating the interoperability and reusability among heterogeneous IoT applications and various physical devices. This study addresses these issues to propose a novel Sensor Web 2.0 as a Service, called SWaaS, which is a fundamental IoT service model. The SWaaS is developed based on a Multi-layer Sensor Web 2.0 Architecture (MSWA) that is composed of Sensor Web 2.0 Mashup technologies to associate with cloud computing environment to facilitate IoT applications development. To demonstrate the feasibility of this approach, this study implemented a Campus Monitoring System that is a IoT application developed based on SWaaS to provide continuous and context-aware monitoring of campus status.
