| Abstract | The transmission of multimedia data over wireless networks is one of the most challenging tasks posed to the communication systems in the last years. The massive amount of data that characterizes multimedia signals, together with the strict Quality of Service (QoS) requirements on bandwidth, delay, and delay jitters, makes the traditional transmission protocols inadequate. The current Internet infrastructures can only support best-effort services, which impose varying network conditions and can not grant any maximum delivery delay. These inconveniences are further exacerbated by the introduction of wireless channels and the interconnection of heterogeneous networks, which increase the variability of transmitting conditions. Previous works have shown that the QoS level can be significantly increased adapting, at each layer, the parameter values to the transmitted information and the network conditions. However, these results can be significantly improved allowing the separate protocol layers to interact and tuning their parameter setting via a joint optimization procedure. This report provides a short insight about some of the cross-layer schemes for wireless video communications that are proposed in literature. |
