Development and Quantitative Analysis of an Adaptive Scheme for Bluetooth and Wi-Fi Co-Existence

A smart radio algorithm to supplement the adaptive frequency hopping (AFH) scheme used by Bluetooth devices is developed and studied. The investigation focuses on the media access control (MAC) layer of the Bluetooth. Collision detection, and Bluetooth channel hopping information are used to detect when an IEEE 802.11 wireless access point (AP) is operating and the AP's radio frequency (RF) channel number (1 through 11). The algorithm then adapts the Bluetooth device to avoid the spectral region occupied by the AP. The performance of this scheme is tested via simulation, and compared with the native AFH system employed by Bluetooth devices.
