摘要
针对无线Mesh网络环境下视频数据传输的延迟、吞吐量、丢包率等问题,改进了一种数据映射方案,将不同重要程度的数据与IEEE 802.11e中的接入类别相对应,优先发送级别高的数据。对压缩视频数据传输进行了仿真实验,并对仿真结果进行了分析,证明了在不同的网络业务负载下,改进的映射方案对网络性能有一定的改善。
In this paper, a data mapping program is improved to solve the problems in video trandmission such as delay, throughput, packet loss in wireless Mesh network. Data of different importance is mapped to access categories in IEEE 802.11e. High level data has priority to be sent. Compressed video data transmission is used to simulation, and the result of experient is analyzed to prove that improved mapping program makes the network performance better in different network load.
