Abstract

IEEE 802.11b Wireless Local Area Networks (WLAN) and Bluetooth Wireless Personal Area Networks (WPAN) provide complimentary services using the same unlicensed radio frequency band of operation. As the benefits of utilizing these services become increasingly apparent, the likelihood of mutual interference may also increase. In this paper an algorithm called Interference-Aware Adaptive Frequency Hopping (IAFH) is proposed and implemented on Bluetooth devices to mitigate the interference between WLAN and WPAN. An analytical channel model of IAFH based on the standard path loss-log normal shadowing-AWGN and Rayleigh multi-path fading channel model is developed to evaluate the performance of the 802.11b devices in the presence of Bluetooth devices. Numerical analysis of the model is done in MATLAB to calculate the throughput of the system using the existing algorithms and the proposed algorithm and the results are compared.
