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

The increasing popularity of wireless services and devices necessitates high bandwidth
requirements; however, spectrum resources are not only limited but also heavily …

We investigate the problem of streaming multi-user videos over the downlink of a cognitive
radio network (CRN), where each cognitive user (CU) can access one channel at a time. We …

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 …

The ultimate objective of medical cyber-physical systems is to enhance the safety and
effectiveness of patient care. To ensure safe and effective care during emergency patient …

Recently, the problem of video streaming over cognitive radio networks has attracted the
attention of the research community due to the multiple challenges facing it. These …

This paper studies the performance of hierarchical modulation-based multimedia
transmission in cognitive radio (CR) systems with imperfect channel sensing results under …

This paper addresses the problem of optimal resource allocation in a multi-hop cognitive
radio networks. The objective of the present work is to search for the shortest possible path …

Cognitive radio (CR) has emerged as an effective solution to spectrum scarcity problem
which efficiently utilizes the unused spectrum of licensed primary user (PU). Video …

In this paper, we propose an adaptive scheme to deliver scalable VoD streams over a
cognitive radio network (CRN) that consists of a base station (BS) and multiple secondary …
