摘　　要：建立了无线个人区域网(WPAN)网络模型,分析了影响网络数据传输性能的因素。推导了WPAN数据吞吐率和蓝牙跳频序列汉明互相关性能以及蓝牙微微网数量三者之间的关系,采用AES算法生成跳频选择序列代替原有蓝牙算法,改善了WPAN网络数据传输,并进行了计算机仿真。使用SOC平台和CSR公司的Bluecore4蓝牙模块两套方案对仿真结果进行验证,证明了理论分析的正确性。在此结果的基础上得出,采用汉明互相关性能更优秀的AES跳频序列选择算法可以提高WPAN网络的数据传输性能。A Wireless Personal Area Network（WPAN）model is proposed,and the factors that affect the WPAN throughput are analyzed.The relations among the WPAN throughput,the hamming correlation of Bluetooth Frequency Hopping（FH）sequence and the number of Bluetooth piconets are derived.The algorithm of Bluetooth FH sequence selection is replaced by Advanced Encryption Standard（AES）algorithm to improve the throughput of WPAN.Simulation and testing results with SOC platform and CSR＇s Bluecore4 Bluetooth module validate the theoretical analysis and the derived relations.It is demonstrated that the AES algorithm can improve the throughput of WPAN.
