A Sensor Service Framework for Context-aware Applications
Hiroyuki Sakamoto, Hiroshi Igaki, Masahide Nakamura (Kobe Univ.)
Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, context-aware applications which estimate contexts with sensors and provides services according to the contexts are widely developed.
In most of such applications, the application and sensors are tightly-coupled.
This causes the implementation of the application becomes more complicated.
Furthermore, network load between the application and sensor increases severely with increase of the number of sensors.
In this paper, we propose a sensor service framework.
The framework wraps sensor-specific logic into a sensor service.
A context-aware application can access any sensors with standardized APIs of the services.
Moreover, the application delegates a part of context estimation process.
Due to the delecation, network load is minimized because the application communicates with the sensor only when the status of estimated context is changed.
We developed some sensor services as case study with our sensor service framework.
