Abstract

Videoconferencing transmission over wireless channels presents relevant challenges in mobile scenarios at vehicular speeds. Previous contributions are focused on the optimization of the transmission of multimedia and delay‐sensitive applications over the forward link. In this paper, a new Quality of Service (QoS) parameter adaptation scheme is proposed. This scheme applies the Cross‐Layer Design technique on the reverse link of an 1xEV‐DO Revision 0 channel. As the wireless channel parameters and the vehicle speed have significant influence in the network layer packet loss rate, it is proposed that the data rate generated by the application adapts itself to the throughput offered by the lower layers as a function of such packet loss rate. Simulations of the proposed model show a significant reduction in losses caused by wireless channel impairments and vehicle mobility, resulting in an improvement in the performance of the mobile videoconferencing session.
