Abstract

Bluetooth provides different kinds of data packet types with different sizes and error correction mechanisms, thus adapter layer can choose the most suitable packet to be transmitted according to the error rate on the link and application requirements. Based on the acknowledgement history of the most recently transmitted packets, an adaptive algorithm is proposed to choose the suitable Bluetooth data packet for transmission through maximizing the expected throughput efficiency of ARQ protocol on Bluetooth ACL data communication link. Simulation results indicate that this method works very well with a short observation history and also show special performance of DM and DH data packet transmission.
