Sensor virtualization with self-configuration and flexible interactions
Pål Evensen, Hein Meling · 2009
This paper presents the design and implementation of a simple and elegant middleware architecture providing virtual sensors as representatives for any type of physical sensors. With our middleware, external applications can seamlessly discover sensor-hosted services through Zeroconf and it provides a standardized communication interface that applications can use without having to deal with sensor-specific details. The limited capabilities of most types of sensors prevent the inclusion of a full communication stack with IP addressing. Yet, through the use of virtual sensors, a uniform communication interface based on UDP/TCP sockets can be exposed to external applications. This will significantly simplify application development for integrated services involving multiple types of sensors.
