Abstract [sv]

Ökningen av sensor-assisterade tillämpningar såsom sensorkampanjer och interaktioner i storskaliga befolkningar ställer nya krav på smidig delning av sensor-information i global skala. Befintligt stöd är begränsat på grund av förenklade informationsmodeller återspeglar smala applikationsscenarier med dåligt skalbarhet i arkitekturer. Som svar på detta presenterar vi en tillämpningsarkitektur för allstädes Internet-av-saker applikationer som kringgår dessa begränsningar. Vår arkitektur gör att program kan använda information från sensorer och trådlösa sensornätverk via en peer-to-peer-overlay. Den överlagrade delade sensorinformation i en generisk informationsmodell, som är utbyggbar och därmed möjliggör intelligent tillämpningsbeteende. Vår utvärdering av arkitekturen visar att det stöder delning av sensorns information i en global skala i sensor-assisterafe tillämpningar med låga svarstider. Slutligen utvärderar vi möjligheten att köra sådana ansökningar i slutet enheter med begränsade resurser i en sensor-assisterad tjänsteprototyp.

Abstract [en]

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 architectures. In response to this, we present an application architecture for pervasive internet-of-things applications which circumvents these limitations. Our architecture enables applications to utilize information from sensors and wireless sensor networks via a peer-to-peer overlay. The overlay shares sensor information in an generic information 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.
