A novel family of frequency hopping sequences for multi-hop Bluetooth networks

The Bluetooth technology is expected to be of the fastest growing which enable consumer electronic devices to connect and communicate via short-range links. The Bluetooth radio operates on frequency hopping over the 2.4 GHz band at 1600 hops/s. In this paper, a novel family of frequency hopping sequences based on 3DES iterated block cipher is proposed for Bluetooth multi-hop networks. The design offers a class of Bluetooth hopping codes with large family size, good impedance and a uniform spread over the ISM frequency bandwidth, which supports jumping of unit between piconets. With the performance of packet error and throughput for synchronized multi-hop Bluetooth network being derived in theory, many numerical results shown that the proposed sequences perform as well as random patterns in terms of multiple access of piconets. Efficiently implemented in FPGA, the generator prototype of the proposed sequence has been realized and is well suited for employment in the Bluetooth radios.
