A distributed architecture of Sensing Web for sharing open sensor nodes

Sensing Web is a conceptual framework to shares sensors openly in wide-area network by maintaining privacy. Sensing Web targets large data such as image data or voice data, which may include privacy information. In this paper, we propose an architecture named SW-agent to realize the idea of Sensing Web. SW-agent protects privacy information by elimination of privacy information and appropriate access control. The elimination is done with data processing by a remote execution program shipped to a node near a sensor. We found that an SW-agent can execute a remote execution program with up to 7% overhead in performance compared to its direct execution.

Research highlights
► We revealed issues of design for sharing sensor data on open systems.
► Maintaining privacy and reducing network traffic is absolutely imperative.
► We proposed a distributed architecture to share sensors openly by maintaining privacy.
► Our framework eliminates needless data through data processing near sensors.
