Cross-Layer Design for Videoconferencing Applications in WiMAX 802.16e Networks

Transmission of real time videoconference sessions using wireless technologies presents important challenges. Channel impairments have a great effect in the quality of the video signal even in cases where emerging broadband technologies such as WiMax are used. This paper describes a proposal based on Cross-Layer-Design for reducing the data packet losses and its impact in the perceived quality of the received signal.
