Recent smartphones are equipped with various sensors, such as an accelerometer, GPS, and a gravity sensor, and have high-performance wireless communication capabilities. Through the ubiquitous presence of powerful mobile devices, crowdsensing lets ordinary people collectively gather and share real-time multimedia data. Multimedia crowdsensing has made large-scale participatory sensing viable in a...
The devices most often used for IT services are changing from PCs and laptops to smart phones and tablets. These devices need to be small for increased portability. These technologies are convenient, but as the devices start to contain increasing amounts of important personal information, better security is required. Security systems are rapidly being developed, as well as solutions such as remote...
We present an architectural framework that provides the foundation for building smart object systems and uses a document centric approach utilizing a profile based artefact framework and a task based application framework. Our artefact framework represents an instrumented physical smart objects as a collection of service profiles and expresses these services in generic documents. Applications for...
This paper designs LS-ware (Large-Scale USN middleware) in order to collect and save large-scale sensing data and to analyze collected data and run status sensing function. LS-ware not only provides USN middlewarepsilas basic function such as Meta information, quality process, or status management, but also makes large-scale sensing data light-weighted and provides a suitable event processing feature...
