As a new evolutionary algorithm, QUasi-Affine TRansformation Evolutionary (QUATRE)
algorithm has excellent performance and scalability, and many different specific high …

Cognitive communications has attracted a large interest during the last decade due to
spectrum scarcity. In combination with multiantenna techniques, cognitive communications …

Femtocells, which are low cost low power, stand alone cellular access points, are a potential
solution to provide good indoor coverage with high data rate. However, the femtocell …

In a heterogeneous network (HetNet), small cells such as femtocells considered in this work
are deployed jointly with macrocells. This new cells' layer, when added to the network …

Femtocells have been introduced as a solution to poor indoor coverage in cellular
communication which has hugely attracted network operators and stakeholders. However …

We propose Femto-cell power control scheme in HeNet with Game Theory. The Femto-cell
which provide high quality with low power is issued by many benefits, however there is a …

Our simulation results showed that learning-based dynamic ABS scheme was 4.% higher
than that of the static ABS scheme. Finally, by integrating the mechanisms of dual …

To encounter the growing demand for high data-rate because of innovative new devices and
data services, mobile network operators are considering deployment of small cells resulting …

To deal with the increasing demand of high speed data streaming and good quality voice
traffic from mobile users at home, Femtocell Networks are deployed in homes that enables …

The effective cross-tier interference (CTI) mitigation is a key technique for the macrocell and
femtocell two-tier heterogeneous networks. In this paper, a cognitive radio relay selection …
