The cognitive radio is an emerging technology that enables dynamic spectrum access in
wireless networks. The cognitive radio is capable of opportunistically using the available …

Cognitive radio networks (CRNs) have emerged as an essential technology to enable
dynamic and opportunistic spectrum access which aims to exploit underutilized licensed …

In a two tier cellular network-comprised of a central macrocell underlaid with shorter range
femtocell hotspots-cross-tier interference limits overall capacity with universal frequency …

In two-tier networks comprising a conventional cellular network overlaid with shorter range
hotspots (eg femtocells, distributed antennas, or wired relays) with universal frequency …

Both the cognitive radio (CR) and the fifth generation of cellular wireless standards (5G) are
considered to be the future technologies: on one hand, CR offers the possibility to …

In this paper, interference mitigation through downlink power control is considered for
macrocell Femtocell overlay. Specifically, the strong interference in the downlink from the …

We consider power control in cognitive radio networks where secondary users identify and
exploit instantaneous and local spectrum opportunities without causing unacceptable …

We consider a scenario in which frequency agile radios opportunistically share a fixed
spectrum resource with a set of primary nodes. We develop a collaborative scheme for a …

In cognitive radio networks, power control is necessary to not only decrease the interference
among the secondary users (SUs), but also avoid negative impact to the primary users …

In this work, we consider Quality of Service (QoS) guarantee for Device to Device (D2D)
users co-existing with a cellular system where the D2D communication links are sharing …
