Summary
Energy consumption of wireless networks is dramatically increasing due to the persistent growth of wireless users, devices, applications and the demand of challenging performance. Hence, the convergence of wireless communication systems and green solutions becomes natural and critical. In addition to the environmental benefits, other motivations for having green solutions include economic benefits to the operators (less energy cost) and practical benefits to the users (longer battery usage). Thus, it is now indispensable to shift from pursuing optimal spectral efficiency to efficient energy usage when creating future wireless networks. Besides, it is accepted that emerging technologies of massive multi-antenna systems, dense heterogeneous networks, cloud radio access networks, M2M (machine to machine) communications and energy harvesting communication systems will be part of future wireless networks (5G networks and beyond). The objective of this research is to optimize the energy efficiency of future wireless systems by proposing innovative green solutions and concepts. This objective will be attained through exploring innovative energy-efficient transmission techniques and advanced original energy-efficient resource allocation schemes for the emerging wireless technologies. Resource allocation will be tackled through theoretical approaches to formulate, solve and find the optimal solutions and performance bounds. Also, less-complex suboptimal and adaptive solutions using heuristic, centralized or distributed approaches will be proposed. Performance evaluation using analytical tools and simulations will be performed. In addition, innovative energy-efficient transmission techniques will be explored.
