Abstract
In this paper, a novel approach is proposed to transmit data in a Bluetooth-based medical body area network (BT-MBAN). The characteristics and requirements analysis of MBANs indicate that the rate of data transfer in an MBAN is low, for most medical application scenarios, compared to the capabilities of Bluetooth. As such, the Bluetooth polling system wastes energy and hence a cross-layer interaction is proposed based on queueing theory and hold mode in Bluetooth. The core idea is that Bluetooth devices buffer data and enter hold mode with an estimated hold duration till the state of buffer reaches a set threshold, and then transmit data over an estimated active time before the next hold mode, determined by the application data profile. The analysis shows that the employment of an M/G(M/M)/1/N queueing model and hold mode in Bluetooth can improve power efficiency significantly for data transmission in many MBAN scenarios. Simulation results of the power consumption savings are given. Finally, optimization of parameters and related issues about the approach are discussed.
