Bluetooth handover control for roaming system applications

Bluetooth has emerged as a versatile low cost wireless communication technology that could be targeted at wireless applications with a service range varying up to approximately 100 m. To be able to provide continuous quality services while the user is moving around at walking speed among different piconets, an efficient handover technique would become evidently necessary. The key principles of handover in Bluetooth lies in finding the Bluetooth address of the device to connect to and be able to synchronize fast enough to it, in order to reduce the connection time. The paper discusses three methodologies that could be used to provide soft handover of a Bluetooth device between different masters or base stations.
