Wireless access to internet via Bluetooth: performance evaluation of the EDC scheduling algorithm

Bluetooth is an emerging technology for constructing adhoc wirelessPersonal Area Networks (WPANs). In this paper we analyze aninnovative scheduling algorithm for asynchronous data trafficspecifically tailored to the Bluetooth characteristic. Thisalgorithm, named Efficient Double-Cycle (EDC), dynamically adaptsthe polling frequency to the traffic conditions. By considering ascenario where a Bluetooth master is used as wireless access pointto the Internet, we show that our EDC scheduler significantlyenhances the system performance with regard to a Round Robin (RR)scheduler.
