Enhancing the Channel Utilization of Asynchronous Data Traffic over the Bluetooth Wireless Ad-hoc Network

by Wu, Jain-Wei

Abstract (Summary)
Bluetooth is an emerging technology to build a solution for providing short range, low power, low cost, and ubiquitous wireless environments. In this paper we propose a algorithm for asynchronous data traffic at the Medium Access Control (MAC) layer to meet Bluetooth characteristic and compare with other scheduling algorithms. The algorithm, named Efficient Utilization Polling (EUP), uses a single bit of the payload packet header as supplied knowledge of queues of slaves to the master to dynamically adapt the polling intervals. We also propose a differentiation mechanism, named Shifting Polling Window (SPW), which is based on EUP and differentiates throughput between different classes and still keeps the link utilization almost the same.
