Enhancement of throughput in Bluetooth through adaptive approaches in diverse environment

Abstract

Effectively communicating in a crowded ISM band with various Radio Access Technologies is challenging. Coexisting technologies in this band have different data rates and bandwidth, affecting service quality and data transfer capacity. Bluetooth, as an ad-hoc network, needs less bandwidth but is more vulnerable. Assessing channel quality and adjusting transmission schedule can enhance Bluetooth's throughput. Channel quality is determined by analyzing the latest received packet to select modulation technique, power level, and packet type. A MATLAB simulation model in Simulink includes various sources of interference to evaluate Bluetooth performance in a diverse wireless environment. Results show that selecting appropriate modulation techniques and data packets based on channel quality improves performance in the presence of other wireless technologies. Throughput of Bluetooth can increase by 14.92% by following this approach, nearly reaching the standard maximum data transfer rate. The framework supports different data packets, power levels, and modulation techniques for Bluetooth transmission, offering a simple way to enhance Bluetooth performance in diverse environments.
