Peer to Peer Video Streaming in Bluetooth Overlays

As Bluetooth is available in most personal and portable terminals (eg, cellular phone, PDA, videocamera, laptop, etc) P2P video streaming through Bluetooth networks is now a reality. Camera equipped Bluetooth phones capture video and broadcast it to other Bluetooth devices and to the infrastructure. Traditionally, large scale Bluetooth networks were designed using scatternet concepts. However, many Bluetooth devices do not support Scatternet connections and, even if they support it, they provide only very limited features suitable mostly for static environments. In high mobility situations, a traditional Scatternet design is not useful because of frequent disconnections and reconnections. To overcome these problems, the authors propose Overlaid Bluetooth Piconets (OBP) and Simplified Overlaid Bluetooth Piconets (SOBP) that interconnect Piconets forming virtual Scatternets.
