Distributed audio recorder using smart phones and proximity connections

A set of smart phones distributed in space may constitute a powerful recording device that is able to create audio/video recordings of social events in a location-aware manner. Such events are formal and informal meetings with 2 or more participants. If each person has a smart phone, this can be programmed to record his speech and skip the speech of the rest of people. Proximity networking capabilities let the individually recorded content be aggregated and distributed to each smart phone.In this paper we analyze such a scenario in which Symbian S60 platforms with Bluetooth version 1.2 stack were used. A distributed recording and content delivery framework is proposed and its performance analyzed by means of simulation and measurements. The validation of our algorithm has been performed using a prototype implementation over these platforms.
