Robust streaming of video over 802.11 wireless LANs (WLANs) poses many challenges, including coping with transmission packet loss and packet data error. In order to reach that, it is very critical for network to identify each video frame and to know the decoding priorities for each video frame. In this paper, a new cross-layer design technique, deep packet inspection (DPI) technique, is proposed to...
We developed a simulation set-up that can test the behaviour of streaming applications over an error-prone wireless networks: 802.11b/g specifically. The application we tested is a video coder that adds unequal error protection to the scalable extension of H.264/SVC. This protection mechanism enables the recovery of lost packets. We adapted a radio wave propagation model to define Rayleigh fading...
