Interference‐aware frequency hopping for Bluetooth in crowded Wi‐Fi networks
Jaewoo So, Y. Kim · Electronics Letters · 2016
A new interference‐aware frequency hopping (IAFH) scheme for Bluetooth to mitigate the interference from Wi‐Fi networks is proposed. The conventional adaptive frequency hopping (AFH) scheme classifies channels into ‘good’ or ‘bad’ according to the predefined threshold and uses good channels with a uniform hop probability. Unlike the conventional AFH scheme, the proposed IAFH dynamically classifies channels into ‘good’ or ‘bad’ according to the observed interference levels and uses good channels with non‐uniform hop probabilities. The simulation results demonstrate that the proposed IAFH scheme significantly outperforms the conventional AFH scheme.
