UbiPAN: A Bluetooth Extended Personal Area Network

Most mobile devices are now Bluetooth-enabled. This wireless technology makes it possible to transfer files or stream contents between pieces of equipment. The possibly many devices that are in reach of each other and thus connected constitute a Personal Area Network (PAN). The problem remains that because of radio range setting up such connections is only possible for devices in a limited area. This paper presents the UbiPAN network infrastructure, the goal of which is to overcome this limitation. It relies on the combination of the IP network, SIP and Bluetooth. This original approach thus has been validated through a file exchange scenario between remote devices that have been seamlessly interconnected.
