摘要
CSMA/CA协议与CSMA/CD协议的差异使数据流间的竞争具有与有线网络不同的特性。该文通过在无线Mesh网络实验床上进行的实验对无线数据流间的竞争进行研究。实验结果表明,在共享信道的无线Mesh网络中,UDP数据流在与TCP数据流的竞争中体现出较为明显的优势,而在TCP数据流间的竞争中,下行TCP数据流的吞吐率稍高于上行TCP数据流,2跳TCP数据流的吞吐率高于3跳TCP数据流。
In view of the differences between CSMA/CA protocol and CSMA/CD protocol, the characteristic of stream competition is different from the one of cable network. The stream competition among wireless data is researched by the experiment conducted in Wireless Mesh Network（WMN） bed. Experimental results show the fact that UDP stream is much more dominant than TCP stream in sharing channel WMN, the throughput of downlink TCP stream is higher than uplink TCP stream, and the throughput of two-hop TCP stream is higher than three-hop TCP stream.
