Bluetooth Scatternets: An Enhanced Adaptive Scheduling Scheme

Simon Baatz, Matthias Frank, Carmen Kühl, Peter Martini, Christoph Scholz

Abstract:

The vision of ad-hoc networking with Bluetooth includes the concept of devices participating in multiple "piconets" and thereby forming a "scatternet". However, the details of scatternet support for Bluetooth are not specified yet. This paper presents a scheme for Bluetooth scatternet operation that adapts to varying traffic patterns. Basing on sniff mode, it does not require substantial modification of the current Bluetooth specification and may thus be incorporated into currently available Bluetooth products. We present simulation results that confirm the applicability of our approach to realistic scenarios.
