| Bluetooth is a universal radio interface developed for enabling electronic devices to connect and communicate via short-range radio networks. The technology allows design of low cost, low power radios that can be embedded in a wide range of electronic devices. Bluetooth operates in the unlicensed Industrial-Scientific-Medical (ISM) band at 2.4 GHz using frequency hopping to minimize radio interference.; The basic Bluetooth network topology is a single-hop star-shaped piconet where a master (in the middle of the star) communicates with the slaves (in the corners of the star). Several such piconets can be interconnected into a scatternet, which then resembles an ad hoc multi-hop network. The interconnection of piconets into scatternets is an open research problem.; This thesis proposes a new dynamic and distributed protocol to interconnect single-hop piconets into ad hoc networks to form a larger scatternet . Our proposed protocol was developed strictly within the constraints imposed by the Bluetooth standard, i.e., without assuming any outside knowledge on the topology of the underlying connectivity graph or attributes of different nodes. We have extended B1ueHoc, a Network Simulator based Bluetooth Simulator to study the performance of the new scatternet formation protocol. |
