A Mobility Model and Dynamic Scatternet Formation for Wireless Personal Area Networks with Portable Bluetooth Devices

Abstract: Bluetooth is a mature technology for a variety of personal computing devices, which are interconnected to form a wireless personal area networks (WPANs). The topology of the WPAN is known as scatternet, which consists of the portable Bluetooth devices. This paper presents a proposed mobility model for the portable Bluetooth devices. Based on the mobility model a dynamic scatternet formation is developed for WPANs that interconnects portable Bluetooth devices. The proposed approach constructs a scatternet within three phases: scatternet backbone formation, device movement detection, and scatternet reformation. Finally, the paper demonstrates the approach with a practical case and then discusses the topics for further study. Keywords: WPAN, scatternet, mobility, Bluetooth.
