Bluetooth scatternets may be operated in a loosely coupled mode, called Walk-In Bridge Scheduling, in which the master polls all of its slaves and bridges using E-limited service. Using the theory of queues with vacations, we derive the stability criteria for packet queues in piconet masters, slaves, and bridges. We show that the stability of the slave queues is more critical under high traffic locality,...
Performance of Bluetooth scatternets is critically dependent on the algorithm for bridge scheduling. As the current specification does not prescribe any particular algorithm, a number of proposals have been made. These proposals are classified into rendezvous-based and walk-in based algorithms, and their relative advantages and disadvantages are highlighted. Using the theory of queues with vacations,...
