| Abstract: | 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. |
