Energy efficiency in cellular networks is a growing concern for cellular operators to not only
maintain profitability, but also to reduce the overall environment effects. This emerging trend …

One of the most engaging challenges for mobile operators today is how to manage the
exponential data traffic increase. Mobile data offloading stands out as a promising and low …

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 …

Small cell networks (SCNs) are envisaged as a key technology enabling the fifth-generation
(5G) wireless communication system to address the challenge of rising mobile data demand …

In this paper, we study the problem of cooperative interference management in an OFDMA
two-tier small cell network. In particular, we propose a novel approach for allowing the small …

We describe a method for obtaining the principal objects, characters and scenes in a video
by measuring the reoccurrence of spatial configurations of viewpoint invariant features. We …

Local IP Access (LIPA) and Selected IP Traffic Offload (SIPTO) are two topics currently of
high interest to mobile network operators. They enable data traffic offload at appropriate …

In this paper, we consider a two-tier heterogeneous cellular network (HCN) where
macrocells and distributed low power cells, namely daughtercells, are operated in a …

Energy efficiency in cellular networks has received significant attention from both academia
and industry because of the importance of reducing the operational expenditures and …

The concept of femtocell access points underlaying existing communication infrastructure
has recently emerged as a key technology that can significantly improve the coverage and …
