This paper proposes an energy management framework for cellular heterogeneous
networks (HetNets) supported by dynamic solar powered drones. A HetNet composed of a …

In this paper, we propose a novel optimization model for multiple Unmanned Aerial Vehicles
(UAVs) working simultaneously as relays to help two set of ground users; namely relay users …

The problem of joint power and admission control (JPAC) is a critical issue encountered in
underlay cognitive radio networks (CRNs). Moving forward towards the realization of Fifth …

Visible Light Communication (VLC) is a rapidly growing technology which can supplement
the current radio-frequency (RF) based wireless communication systems. VLC can play a …

In this paper, we design a new collaboration interference (CI) transmission scheme for
overlay cognitive full-duplex wireless wiretap networks, where a full-duplex secondary user …

This paper investigates a multi-band harvesting (EH) schemes under cognitive radio
interweave framework. All secondary users are considered as EH nodes that are allowed to …

Device‐to‐device (D2D) communication can effectively use cognitive radio network
approach to coexist with cellular users. For such a cognitive D2D system, two approaches …

In this paper, we consider a two-way cognitive cooperative radio network (TW-CCRN) with
hybrid interweave-underlay spectrum access in the presence of imperfect spectrum sensing …

In this paper, a new and novel approach called (Unmanned Areal Vehicle) UAV-Direct is
proposed, where the UAV helps in optimizing the bandwidth and power allocations of …

Massive MIMO systems were utilized in overlay Cognitive Radio (CR) networks to allow
simultaneous primary and secondary data transmission while enhancing the spectral …
