Purpose To present a combination of Bluetooth handoff techniques and scatternet formation to adapt to varying topologies and traffic changes. Design/methodology/approach Through ad hoc networking with Bluetooth, devices could participate in multiple piconets, which form the scatternet. Although the details of scatternet implementation are not specified in the Bluetooth specification, much research has been carried out to propose different models of implementation. This paper presents a combination of the techniques of handoff and scatternet formation to adapt to varying topologies and traffic changes. Analysis of network performance is presented to confirm the feasibility of real implementation. Findings Provides a novel and practical design, compatible with Bluetooth specification, which is shown by experimental results to be an efficient design in providing a scatternet formation approach, while at the same time maintaining a low data error rate to support data and voice. Originality/value This paper presents Bluetooth handoff and scatternet formation techniques to extend geographical coverage and increase system capacity with adaptation to varying topologies and traffic changes. The techniques presented are compatible with Bluetooth specifications 1.0, 1.1 and 1.2.
