This paper provides an overview of the use of small cells (eg, femtocells) in the Internet of
Things (IoT) environments. As a result of rapid increase in the number of mobile connected …

The current mobile communications could not satisfy the explosive data requirement of
users. This paper reviews the frontier technology of software definition networks (SDN) of 5G …

The dense deployment of small cells in 5G cellular networks raises the issue of controlling
downlink inter-cell interference under time-varying channel states. In this paper, we propose …

To provide efficient content sharing service in a mobile social networks (MSNs), the social-
aware cooperative caching mechanism is proposed. The mechanism considers the social tie …

With the rapid growth of vehicles, the vehicular networks meet main challenges such as
dynamic, heterogeneous, and large scaled. In addition, the cellular-based vehicular …

In order to improve the spectrum efficiency and secrecy energy efficiency, in this paper, we
propose a non-orthogonal multiple access (NOMA)-based secure scheme for cognitive radio …

This study considers the outage and throughput performance of downlink in the secondary
network of cognitive radio assisted non-orthogonal multiple access (NOMA) systems. Both …

The spectrum sensing is a key process of the cognitive radio technology in which the
cognitive users identify the unutilized/underutilized primary users (PUs)/licensed users …

In this paper, the non-orthogonal multiple access (NOMA) technology is integrated into
cognitive orthogonal frequency-division multiplexing (OFDM) systems, called cognitive …

Caching the most popular contents at the wireless network edge such as small-cell base
stations (SBSs) is a smart way of reducing duplicated content transmissions and offloading …
