Interference mitigation in coexisting bluetooth and WLAN network using power efficiency method

The number of devices equipped with IEEE 802.11 and Bluetooth technology are growing drastically, therefore interference may occur between the co-located devices in the 2.4 GHz ISM frequency band. This paper discusses the interference problem between this two co-located devices and intends to find improvement of the existing solutions for this coexisting issue. In addition to this, we consider the power allocation for channels to make the data transmission more energy efficient. We propose the idea of defining different power levels for different clusters according to their packet error rate (PER). In order to reduce the interference between the coexisting Bluetooth and WLAN networks, we determine the PER for each channels, sort them into clusters according to their PER and then provide a more power efficient data transmission through the interfered channel. Simulation results show that our proposed algorithm has better power efficiency and outperforms the interference mitigation techniques of the existing mechanisms.
