摘　　要：通过计算研究无线局域网中业务流的自相似性和仿真实验,研究无线局域网中基于自相似业务的RED算法的性能。仿真结果表明由于业务流的自相似性的负面影响和无线网络本身特点的影响,RED算法和Drop-Tail算法的性能差别不大。由于Drop-Tail算法简单易行、开销较低,建议在无线接入点采用Drop-Tail算法进行拥塞控制。The self-similarity of the traffic in WLANs is studied to show that the wireless traffic tends to have a self-similar behavior. The performance of the RED algorithm is studied under the self-similar wireless traffic in the WLANs by extensive simulation experiments, The simulation results show that there is little performance difference between RED and Drop-Tail algorithms because of the negative effects of the self-similar traffic and the features of the WLANs. The Drop-Tail algorithm can be employed at the access point to perform congestion control due to its less complexity.
