  • Abstract Bluetooth is a low cost, low power consumption, short-range radio technology working on the 2.4 GHz frequency band. Recently, several typical polling schemes have been presented to enhance the performance on asymmetric transmissions between the master and slave. However, such polling algorithms consider only either the uplink queue or the downlink queue state for scheduling. In this paper, we propose an algorithm for Bluetooth Piconets scheduling, called the Uplink and Downlink queue Polling Scheme (UDPS). The goal of this scheduling algorithm is to alleviate the wasted bandwidth by diminishing the visit to inactive slaves. Distinguishing from previous polling schemes that have been proposed, this algorithm considers on both uplink and downlink queue states for increasing the throughput and reducing the delay time of the piconets communication.
    This study proposes UDPS, a new Polling Scheme for Bluetooth piconets addresses both Uplink and Downlink queues, considering to remain fair and efficient in asymmetric flow rates. Simulations confirm that the performance of the UDPS compares favorably with that of traditional polling approaches.
