Techniques to improve the performance of TCP in a mixed Bluetooth and WLAN environment

A major challenge for the WLAN technology stems from having to share the 2.4 G Hz ISM band with other wireless devices such as Bluetooth radios. The main goal of this paper is to investigate the use of techniques to mitigate the effects of interference for Bluetooth and WLAN and discuss the resulting performance trade-offs. We compare the performance of the Bluetooth and WLAN systems and evaluate how each technique improves or degrades TCP performance. Simulation results for selected scenarios and configurations of interest are obtained and the performance of Bluetooth and WLAN is measured in terms of packet loss, TCP throughput and delay.
