摘要 IEEE 802.11物理层和MAC具有支持多信道和多速率的能力。在多速率情况下,IEEE 802.11网络产生性能异常问题,低速率链路严重降低了高速率链路的性能,导致系统性能下降。针对该问题,设计了基于均衡算法的协作信道分配(CCA)协议,以解决无线网络中的性能异常问题。CCA的主要思想是通过预估传输时间(ETT)标准和均衡算法来解决信道分配问题。在预估传输时间标准下,CCA通过多信道来分离不同速率链路。通过使用均衡算法,CCA还能增加吞吐量的公平性。仿真结果表明,在无线网状网中,CCA能有效改善网络性能。 Physical and MAC layer of IEEE 802.11 supports multi-channel and multi-rate.In the case of multi-rate,IEEE 802.11 network causes the problem of performance anomaly and low-speed links degrade the performance of high-speed links seriously,which leads to the degradation of system performance.For this problem,a cooperative channel allocation（CCA）agreement was designed to solve the problem of performance anomaly in wireless network.The idea of CCA is to solve channel allocation problem via the criterion of estimated transmission time（ETT） and balancing algorithm.Under the criterion of estimated transmission time,CCA separates links at different speed via multi-channel.Based on balancing algorithm,CCA can also increase the fairness of throughput.Stimulation results indicate that CCA can improve the network performances in wireless mesh networks.
