The development of the fifth generation (5G) wireless networks is gaining momentum to
connect almost all aspects of life through the network with much higher speed, very low …

Today's heterogeneous networks comprised of mostly macrocells and indoor small cells will
not be able to meet the upcoming traffic demands. Indeed, it is forecasted that at least a 100 …

For more than three decades, stochastic geometry has been used to model large-scale ad
hoc wireless networks, and it has succeeded to develop tractable models to characterize …

Femtocells, despite their name, pose a potentially large disruption to the carefully planned
cellular networks that now connect a majority of the planet's citizens to the Internet and with …

The heterogeneous cellular network (HCN) is a promising approach to the deployment of 5G
cellular networks. This paper comprehensively studies physical layer security in a multitier …

Increase in system capacity and data rates can be achieved efficiently in a wireless system
by getting the transmitter and receiver closer to each other. Femtocells deployed in the …

In this paper, we propose a joint subchannel and power allocation algorithm for the downlink
of an orthogonal frequency-division multiple access (OFDMA) mixed femtocell/macrocell …

Support of femtocells is an integral part of the Long Term Evolution-Advanced (LTE-A)
system and a key enabler for its wide adoption in a broad scale. Femtocells are short-range …

Femtocells are assuming an increasingly important role in the coverage and capacity of
cellular networks. In contrast to existing cellular systems, femtocells are end-user deployed …

Fifth Generation (5G) is the final generation in mobile communications, with minimum
latency, high data throughput, and extra coverage. The 5G network must guarantee very …
