Enabling ubiquitous sensor-assisted applications on the internet-of-things
Springer-Verlag London · 2014
The increase in sensor-assisted applications such as sensing campaigns and interactions in large-scale populations put new demands on seamless sharing of sensor information on a global scale. Existing support is limited due to simplified information models reflecting narrow application scenarios and poorly scaling architec- tures. In response to this, we present an application archi- tecture for pervasive internet-of-things applications which circumvents these limitations. Our architecture enables applications to utilize information from sensors and wire- less sensor networks via a peer-to-peer overlay. The overlay shares sensor information in an generic informa- tion model, which is extensible and thus enables intelligent application behavior. Our evaluation of the architecture indicates that it supports the sharing of sensor information on a global scale in sensor-assisted applications, with low response times. Finally, we evaluate the feasibility of running such applications in end devices with limited resources in a sensor-assisted application prototype.
