Optimizing video delivery to multiple users over a wireless channel is a challenging task, especially when the objective of maximizing the spectral efficiency has to be jointly considered with the objective of providing a fair video quality. In this paper a novel cross-layer optimization framework for scalable video delivery over OFDMA wireless systems is proposed, aiming at maximizing the sum of...
A scheme that exploits the broadcast nature of the wireless communication in order to achieve multicast content delivery is presented in this paper. As opposed to broadcasting, this method enables the clients to determine on-line the delivered content, and thus preserves the advantages of an individual service. On the other hand, a multicast content delivery is much more efficient than a unicast content...
Equivalent bandwidth (EqB) is defined as the minimum service rate to be provided to a traffic buffer to guarantee a certain degree of quality of service (QoS) in terms of objective parameters (packet loss, delay, jitter). EqB techniques are usually obtained analytically for homogeneous traffic trunks, with respect to a single QoS constraint. Modern network solutions often imply the aggregation of...
