Unmanned aerial vehicles (UAVs) have found widespread commercial, civilian, and military
applications. Wireless communication has always been one of the core technologies for …

Cognitive radio (CR) is the enabling technology for supporting dynamic spectrum access:
the policy that addresses the spectrum scarcity problem that is encountered in many …

We study the problem of optimal power allocation in a single-hop ad hoc wireless network.
In solving this problem, we depart from classical purely model-based approaches and …

This paper presents an overview of the theory and currently known techniques for multi-cell
MIMO (multiple input multiple output) cooperation in wireless networks. In dense networks …

Cognitive radio technology, a revolutionary communication paradigm that can utilize the
existing wireless spectrum resources more efficiently, has been receiving a growing …

We propose a novel decomposition framework for the distributed optimization of general
nonconvex sum-utility functions arising naturally in the system design of wireless multi-user …

Fueled by ongoing and increasing consumer demand, the explosive growth in spectrum-
based communications continues to tax the finite resources of the available spectrum. One …

Resources in cognitive radio networks (CRNs) should dynamically be allocated according to
the sensed radio environment. Although some work has been done for dynamic resource …

Providing economic incentives to all parties involved is essential for the success of dynamic
spectrum access. Cooperative spectrum sharing is one effective way to achieve this, where …

In this paper, new enhanced cognitive radio networks (E-CRNs) based on spectrum sharing
(SS) and spectrum aggregation (SA) are proposed for fifth generation (5G) wireless …
