Energy Efficiency of Heterogeneous Cellular Networks: A Review

Ayad Atiyah Abdulkafi, Tiong Sieh Kiong, Johnny Koh, David Chieng and Alvin Ting

Abstract:
The concept of heterogeneous networks had been proposed as an alternative approach to provide higher capacity and coverage for cellular networks. Along with that, the aspect of “Energy Efficiency” had already received much attention lately due to ecological as well as economic reasons particularly for network operators. This study presented a systematic review on the topic of energy efficiency in heterogeneous cellular networks. The review was divided into three parts; first the typical metrics parameters used to measure energy efficiency and tradeoff relationships with respect to network performance were discussed. Next, the existing issues, approaches and challenges to provide energy efficiency in general cellular networks were addressed. Finally we looked into the current efforts on energy awareness in macro, micro, pico and femtocells. By means of discussions, we highlighted different heterogeneous network scenarios in which network planning and optimization techniques were (or not were) advantageous to provide essential understanding for successful deployment of green heterogeneous cellular networks.
