The Internet has led to the creation of a digital society, where (almost) everything is
connected and is accessible from anywhere. However, despite their widespread adoption …

This paper presents a comprehensive survey of existing authentication and privacy-
preserving schemes for 4G and 5G cellular networks. We start by providing an overview of …

This two-part paper develops novel methodologies for using fractional programming (FP)
techniques to design and optimize communication systems. Part I of this paper proposes a …

Future wireless communication is expected to be a paradigm shift from three basic service
requirements of 5th Generation (5G) including enhanced Mobile Broadband (eMBB), Ultra …

For conventional wireless networks, the main target of resource allocation (RA) is to
efficiently utilize the available resources. Generally, there are no changes in the available …

Orthogonal Frequency Division Multiplexing Access (OFDMA) has been increasingly
deployed in various emerging and evolving cellular systems to reduce interference and …

In this paper, we introduce distributed caching of videos at the base stations of the Radio
Access Network (RAN) to significantly improve the video capacity and user experience of …

The choice of OFDM-based multi-carrier access techniques for LTE marked a fundamental
and farsighted parting from preceding 3GPP networks. With OFDMA in the downlink and SC …

Interference represents one of the most common barriers for the wireless communications
society to bring the fully connected world to life, where everybody and everything is …

In this paper, network function virtualization (NFV) is identified as a promising key
technology, which can contribute to energy-efficiency improvement in 5G networks. An …
