The future generation networks (5G) are expected to achieve high data rates, reduced
latency, increased spectral efficiency and energy efficiency of the system. Since the …

Spectrum utilization, energy consumption, and cost efficiency are three key performance
metrics that should be jointly investigated in developing a sustainable 5G system. Advanced …

The cellular technology is mostly an urban technology that has been unable to serve rural
areas well. This is because the traditional cellular models are not economical for areas with …

This paper studies online optimization under inventory (budget) constraints. While online
optimization is a well-studied topic, versions with inventory constraints have proven difficult …

Increasing utilization of LTE-Advanced (LTE-A) to meet the rapid growth in wireless
bandwidth demand is an important focus for current research. Dynamic spectrum access …

Reducing the power consumption of base stations is crucial to enhancing the energy
