碩士 === 元智大學 === 資訊工程學系 === 92 === Bluetooth is a new with radio technology low cost and short-range properties. 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 this thesis, we propose a new scatternet formation protocol for Bluetooth networks. We aim to construct a scatternet with longer lifetime. Moreover, our scatternet formation algorithms are based on the characteristics of device, power limited constraint and battery capacity. In this way, we will reduce the construction time of scatternet and balance battery consumption of each device. Finally, we present an algorithm to select a stable routing path for data transmission. From the simulation, it shows our method will generate a scatternet with longer lifetime.
