Due to an increase in the number of operating devices,dealing with the 2. 4 GHz ISM band interference has become very important. Bluetooth specification enables the use of adaptive frequency hopping to improveperformance in the presence of interference. This technique avoids thecongested portions of the ISM Band, however; as the number of interferers increases, a greater number of bad channelsare removed from the adapted hopping sequence. This results in degradation of the operation. In this paper, we present a smooth adaptive frequency hopping (SAFH) Algorithm to improve the performance of frequency hopping in the presence of interference. The model is established and simulated using MATLAB Simulink.
