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 …

Spectrum decision is the ability of a cognitive radio (CR) to select the best available
spectrum band to satisfy secondary users'(SUs') quality of service (QoS) requirements …

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 …

This paper aims to consolidate the work carried out in making base station (BS) green and
energy efficient by integrating renewable energy sources (RES). Clean and green …

Massive Multiple-Input Multiple-Output (MIMO) alludes to the theory of having a large
number of transmitter chains at the base station, which in turn provides the higher spectral …

There is a growing interest in improving the energy efficiency of communication networks to
reduce operational expenditures, to maintain profitability and to make cellular networks …

Effective software maintenance requires a detailed knowledge of the system's artifacts, the
way these artifacts are used or modified and their interrelationships. Based on some useful …

Telecommunication usage has skyrocketed in recent years and will continue to grow as
developing world reaches to wireless as the communication medium of choice. The …

The interference to the primary receiver (PR) is a critical issue in the resource allocation of
cognitive radio (CR) networks. For instance, the nonlinearity of the power amplifier (PA) …

This paper shows how cognitive radio (CR) can help to optimize system power consumption
of multiple input multiple output (MIMO) communication systems. Leveraging results from …
