Bluetooth scatternet formation for supporting device mobility

Abstract

Since most of the Bluetooth devices are portable, the user may bring the Bluetooth devices and roams in the range of a scatternet. Thus, the capability of formatting Bluetooth scatternet under device mobility impacts on the survivability and feasibility of the Bluetooth network. In this paper, we propose a formation algorithm that can construct the Bluetooth scatternet subject to device mobility on basis of our proposed mobility model. The proposed algorithms deal with the moving of a single device, which may be a slave, bridge, or master. Moreover, the proposed algorithms can be extended to support group mobility easily. We also conduct the simulation study to evaluate the performance of the proposed algorithms and discuss some interesting topics for further study.
