Abstract
This chapter aims at evaluating a number of Quality of Service (QoS) indices of a real-time video transmission over an 802.11b ad hoc wireless network. Video is coded according to the state-of-the-art ITU-T H.264 encoder and its transmission is simulated by means of the ns-2 network simulator. Objective quality measurements are presented. Moreover, the impact of different parameters — both at the encoder and at the MAC level —, of background interfering traffic and of the number of relay nodes, is studied, showing the various trade-offs involved.
