Ad-hoc formation of Bluetooth piconet and IP allocation in PAN

This article proposes the Simple Internet Access Procedure (SINAP), which enables IP communication in a Bluetooth piconet where one or more devices may have Internet access. Alternatives for allocation of IP addresses are also discussed. The piconet consists of Bluetooth enabled computing devices, such as laptops, which may have Internet connections over Ethernet, WLAN, or GSM/UMTS. It is formed according to an automatic piconet formation procedure. The procedure provides topology information, which makes it is possible to deploy IP directly on the L2CAP protocol without the need for any adaptation layer.
