Deployment of small cell base stations (SBSs) overlaying the coverage area of a macrocell
BS (MBS) results in a two-tier hierarchical small cell network. Cross-tier and inter-tier …

Cyber-physical systems (CPSs) under denial-of-service (DoS) attacks are investigated in the
present work. Besides multiple controllers in the physical-layer, there exist multiple DoS …

To address the explosive traffic demands, the capacity of the fading channel is increasingly
becoming a prime concern in the designing of the wireless communication system. The …

In this paper, we investigate the coverage performance and energy efficiency of multi-tier
heterogeneous cellular networks (HetNets) which are composed of macrocells and different …

In this paper, we present a novel clustering‐based resource allocation framework for
downlink transmission in ultra‐dense small cell networks. Specifically, we first model a …

This paper proposes a joint energy efficiency (EE) and spectrum efficiency (SE) tradeoff
analysis as a multi-objective optimization problem (MOP) in the uplink of multi-user multi …

Femtocells in two-tier femto-macro networks can enhance indoor coverage and improve
overall network performance. Macro networks may share spectrum with overlaid femtocells …

The rapid escalation of user traffic and service innovation has made the deployment of small
cell base stations essential for eventually decreasing energy consumption in future …

Energy efficiency is a growing concern in every aspect of the technology. Apart from
maintaining profitability, energy efficiency means a decrease in the overall environmental …

Non-orthogonal multiple access (NOMA) is considered as a promising technology for the
fifth generation mobile communications. Energy-efficient resource allocation scheme is …
