Abstract

Sensor networks are increasingly used to provide pervasive environments. These deployment environments entail embedded sensing devices that have limited processing, memory, and battery power. It is therefore essential to devise efficient approaches that can collect low-level sensed data and transform it to a higher, more abstract measurement to relay to the user. This paper introduces the virtual sensors abstraction that enables an application developer to create software sensors that can apply user-specified functions on different types of data to provide a higher-level measurement that is not an intrinsic measurement provided by the physical sensors in the network. We evaluate our implementation of the virtual sensors model in two diverse example domains.
