Dynamic Bluetooth Packet Selection Strategy Based on Wi-Fi White-Space Prediction
edited by: Ruchuan Wang, Fu Xiao
In order to coexist Bluetooth with Wi-Fi in mutual interference environment, carrier sensing and traffic forecasting model are used to optimize the packet selection mechanism in Bluetooth frequency-hopping process. The probability of collisions of Bluetooth signal and Wi-Fi signal is gained by baseband layer energy sampling and Wi-Fi traffic forecasting model. According to the collision probability, the packet types are selected to achieve maximum throughput of Bluetooth. Simulation and analysis show that the algorithm can effectively coexist Wi-Fi with Bluetooth by mean of time divided channel multiplexing in real world Wi-Fi environment.
