Survey of Cross-layer Designs for Video Transmission Over Wireless Networks
Ali Abdulqader Bin-Salem, Tat‐Chee Wan · IETE Technical Review · 2012
AbstractWireless networks are designed to enable a variety of existing and emerging multimedia streaming applications. Multimedia streaming applications demand high quality of service (QoS), especially from wireless networks, because of the problems that exist in these types of environments, including interference, packet loss, delay, reduction of wireless link utilization, and so on. QoS necessitates the utilization of available resources at different layers of the multimedia system components, such as network, terminal, and content. Thus, a new design called cross-layer has been developed and is now considered beneficial by the research community. The aim of the current paper is to present different cross-layer designs or approaches that are classified into many categories. A cross-layer design based on the direction of information (i.e., downward, upward, hybrid, MAC-centric, and joint adaptation) and on the information itself (i.e., channel state information, QoS-related parameters, resources informat...
