Efficient video transmission using network coding over WLAN

In order to effectively transmit multimedia traffic in error prone wireless LAN networks, a novel transmission scheme using soft decision values and symbol-level random network coding over wireless LAN is proposed in this paper. A simple combining technique using soft decision values can improve video quality substantially which is shown with simulations. The proposed WLAN video packet transmission scheme can enhance packet transmission efficiency substantially. The proposed scheme can be used for unequal error protection of video frames for robust video transmission over wireless networks.
