A New Scatternet Formation Protocol for Bluetooth Networks

Abstract

Bluetooth is a new low cost and short-range radio technology. Mobile devices equipped with bluetooth chipset use FH (Frequency Hopping) method in a frequency band of 2.4 GHz to construct a piconet with other chipsets. Different piconets can communicate through relay devices. To date, many researchers have proposed different scatternet formation protocols. However, most of them consider how to fast construct a scatternet with minimal piconets or how to maintain the desired topology. In the paper, we propose a new scatternet formation protocol for Bluetooth networks. We aim to construct a scatternet with longer live time. Moreover, our protocol can maintain the desired scatternet formation even when the topology of the network changes. Simulation results show that our protocol outperforms BTCP in many respects including construction time and network live time.
