Video streaming has become a popular and important type of network application. Meanwhile, wireless LANs has been gaining popularity too. It has thus become important to address the reliability problem for video streaming in wireless LANs and for video streaming from the Internet to the users in wireless LANs. This paper proposes an efficient Automatic Repeat ReQuest (ARQ) scheme to address the reliability problem for video broadcasting in such scenarios. Based on a novel approach of virtual bitmaps, the proposed scheme achieves high efficiency in recovering broadcasting losses in wireless LANs but does not use out-of-band signals.
