本文提出一种自适应包选择延迟发送方法,解决蓝牙与802.11b的干扰问题。这种方法属于非协作共存技术范畴,其原理为:蓝牙单元根据信道质量的不同,选择不同长度的分组和发送时间,以躲避冲突,避免同频干扰。仿真结果说明,此机制使蓝牙与802.11b的丢包率降低到接近零,使802.11b数据包网络通过率提高了近30%。 This paper presents an adaptive packet-selective delay transmission method to solve the interference between Bluetooth and 802.11b. This method belongs to the category of non-cooperative coexistence technology, the principle is: Bluetooth unit according to the different channel quality, choose different length of the packet and send time to avoid conflict, to avoid co-channel interference. The simulation results show that this mechanism reduces the packet loss rate of Bluetooth and 802.11b to near zero, and improves the network throughput rate of 802.11b packet network by nearly 30%.
