A Survey On Bluetooth Scatternet Scheduling Research Trends?

Bluetooth is a promising new technology for short range wireless connectivity between mobile devices. By constructing a piconet, Bluetooth device establishes link and communicates with other devices in a master?slave manner. The piconets are combined to form the Scatternet and communicate through the Relay /bridge node. So the performance of the Scatternet highly depends on the relays and its degree and mobility. This paper describes the issue of piconet interconnection for Bluetooth technology. These larger networks, known as scatternets, have the potential to increase networking flexibility and facilitate new applications .In this survey many research papers were collected concerning various fields in Bluetooth scatternet scheduling and discussed each and categorized them under the few mechanisms and the trends were interpreted based on the area of research and applications.
