Time-critical and delay-sensitive multimedia applications require more spectrum and
transmission resources. With the provision of cognitive radios (CRs), the underutilized …

The stringent requirements of wireless multimedia transmission lead to very high radio
spectrum solicitation. Although the radio spectrum is considered as a scarce resource, the …

The utilization of licensed spectrum provides an opportunity to the cognitive users to utilize
these spectrum bands when unused by the primary users (PU x). The possibility of spectrum …

Accommodating the fast-growing multimedia traffic demands at low cost is critical to ensure
the future competitiveness of cellular networks. Cognitive radio (CR) emerges as a key …

Cross-layer communication could bring a significant performance improvement for wireless
communication systems through allowing information exchanges among multiple layers. For …

Wireless video broadcast/multicast and mobile video communication pose a challenge to
the conventional video transmission strategy (which applies separate digital source coding …

In this paper, a new transmission protocol is proposed for a two-cell network, where each
cell, respectively, has one-uplink and one-downlink data traffic requirement. By designing …

We tackle the challenging problem of streaming multiuser videos over the downlink of a
cellular cognitive radio network (CRN), where each cognitive user (CU) can sense and …

Video streaming, as a bandwidth-hungry and delay-sensitive application, can be supported
with the Cognitive Radio (CR) technology, which is effective in exploiting the underutilized …

Recently, nodes cooperation has emerged as a popular means for improving the quality of
multimedia delivery over fifth‐generation cellular networks. However, in the conventional …
