Energy Efficiency in Wireless Networks – a Composite Review

ABSTRACT

Energy efficiency is one of the most distinguished area on which several research groups and organizations across the globe are progressively working. This paper focuses on various technologies for truncating energy consumption in wireless communication. This incorporates new network architecture, network resource management, and supreme physical layer methods. Network architecture embraces multi-hop mobile networks, distributed antennas, diverse networks, etc. Furthermore, network resource management schemes comprise cross-layer optimization, multiple radio access technologies, and the dynamic power saving. The supreme physical layer methods encompass cognitive radio, multiple-input multiple-output (MIMO), concerted communications, network coding, orthogonal frequency division multiplexing (OFDM), etc. We render an exhaustive survey of such techniques proposed by several organizations across the globe. We also discussed energy efficiency prospect in future wireless communication systems like 5G, mobile cloud computing, Internet of things (IoT), and big data. Finally, we confer the major challenges and open issues in these technologies.

Keywords:

• EE metric
• Energy efficiency
• MIMO
• RRM
• Service differentiation
