摘要
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 puts forward a method of adaptive packet selection and transmitting delay to resolve the interference between Bluetooth and 802. 11b. This method belongs to a kind of noneollaborative coexistence. The Bluetooth devices select different kind of packet and transmitting time according to the quality of channel to avoid overlap. The results of simulation showed this method was efficient to decrease packet loss rate and increase the throughput.
