An integrated approach to scatternet traffic management in Bluetooth ad hoc networks

Scatternet management remains to be one of the most crucial research issues for Bluetooth networks, despite that Bluetooth devices have proliferated in the commercial market. In this paper, we describe our proposed integrated scheme for effective scatternet management. Our proposed scheme contains four main mechanisms to address the different facets of the problem, namely compensation-based time-slot assignment (CTSA), traffic differentiation queueing (TDQ), adaptive master-slave switching (AMSS), and an enhanced AODV algorithm for ad hoc routing. We have built a comprehensive Bluetooth simulator and performed extensive simulations to evaluate the proposed IARTSS. We find that our proposed scheme can perform well under a wide variety of practical circumstances, and provides efficient and high performance intra-piconet and inter-piconet communications.
