N2 - Compared with unicast, video multicast over 802.11 WLANs should handle varying channel conditions of multiple users and user topology changes as well as scalability to achieve good quality for all users in the serving area. This paper analyzes error control strategies available in different layers of the network stack, including modulation and channel coding in physical layer, cross-packet Forward Error Correction (FEC), packet size optimization and scalable video coding in application layer. By combining and adapting these schemes jointly, an adaptive cross layer optimization algorithm is proposed for scalable video multicast over 802.11 WLANs. Based on a variety of criteria, improvement in overall video quality for all the targeted users can be achieved.
