Mobile phones have two sensors: a camera and a microphone. The goal in this position paper it to explore the use of these sensors for building an audio-visual sensor network that exploits the deployed base of millions of mobile phones worldwide. Among the several salient features of such a sensor network, it focuses on mobility. Mobility is advantageous since it yields significant advantage in spatial coverage. However, due to the uncontrolled nature of device motion, it is difficult to sample a required region with a given device. This paper proposes a data based abstraction to deal with this difficulty. Rather than treating the physical devices as the sensor nodes, it introduces a layer of static virtual sensor nodes corresponding to the sampled data locations.
