Eavesdropping wireless video packets to improve standard multicast transmission in Wi-Fi networks

This paper proposes WEVCast, (Wireless Eavesdropping Video Casting) a new mechanism to overcome the performance obtained by wireless multicast transmission of video contents over standard Wi-Fi networks. We described this new strategy pointing out few specific features of our proposal such as the simplicity, the robustness and the extreme compatibility with all off-the-shelf wireless devices; in addition, we validated our idea throughout a quite realistic simulation framework well designed for perceived video quality evaluation. The obtained results confirm the goodness of the proposed solution making it very attractive for the new multimedia video content delivery services.
