Topology constructing and restructuring mechanisms for Bluetooth radio networks

The Bluetooth wireless communication technology which is widely used for short-range communications. It operates on 2.4GHz ISM band. In addition, Bluetooth and IEEE 802.11(Wi-Fi) devices are possible and likely to occur on the specific channel in the same location. Bluetooth devices adopt frequency hopping scheme to prevent the likelihood of mutual interferences. Although the frequency hopping can reduce some interferences, as the Wi-Fi and Bluetooth devices are coexisted in the neighborhood, the performances of both networks will be degraded likely. Because they operate on the same band and can't communicate with each other. An interference aware approach for improving the throughput of a given piconet is presented in this paper. An interference aware piconet restructuring mechanism, called IAPR, is proposed. The proposed models are based on role switch operation. The analytical results show that the proposed IAPR approach further improves the network performance between the Wi-Fi and Bluetooth devices and improves the throughput of Bluetooth radio networks.
