Abstract :
Bluetooth is a wireless ad-hoc network concept using a universal short-range radio link for communicating electronic devices in a small area. The Bluetooth radio nodes form piconets and provide a slotted time division duplex (TDD) scheme in which each slot is 0.625 ms long. This work studies traffic performance in a piconet focusing on "mean packet delay" and "probability of packet loss" of data traffic. A mix of data and voice traffic is used in the simulation where data traffic streams are modeled by an interrupted Bernoulli process. The priority, round robin, and "alternating priority" scheduling schemes are studied and compared. The alternating priority scheme turns out to be a fair and efficient scheme and it has almost as good overall performance as in the priority scheme.
