A Review on Energy Efficient Green Communication
International Journal of Innovative Research in Electronics and Communications
Wireless communication has reached new heights with the increasing subscriber demands thus leading to emerging of environmental problems. It is becoming challenging to maintain the required quality of service in radio frequency communication. The temporary solution adapted by service providers to address the critical issues in radio communication including co-channel interference, adjacent channel interference, crosstalk etc. is to increase the power level of transmitted signal. But at the same
... time, such high power signals may affect living species badly and hence it is required to look forward for an alternate solution to high power signal communication. Green communication is capable to offer an effective solution for addressing these issues. It's mitigation to the problem of CO2 emission and better performance has drawn researcher's attention in past few years. It is also being thought as an energy efficient communication. The upcoming 5G networks are undergoing standardization and need to have least power consumption. This paper deals with reviews about the challenges and opportunities in establishing green communication and various key techniques. Co-operative communication (D2D communication) This communication system is integrated into LTE advanced standards and Wi-Max. A three node wireless network, referred to as "Three-terminal communication channel" is used in this communication system. Space-Time wireless communication (O-STBC, STTC) The wireless communication standard for this system is CDMA2000 and UMTS mobile standards. Space Time Coding (STC)  is a wireless system that engrosses several transmitting antennas and single or many receiving antennas. Multiple antennas have the potential to increase the attainable bit rates, and this was demonstrated by the help of information theory. UMTS depends on data collection which can be accomplished by drive testing and then extended to other cellular data services  .

Other than reducing the energy requirements Green Communication also helps to reduce the emission of CO2 which is a threat to environment and human beings. As studies suggest that green communication has many issues and challenges in terms of cost, spectrum efficiency and bandwidth saving still further research is required to discuss these open issues effectively. The existing techniques to achieve green communication are cognitive network, network coding, Smart Grid and further research is being conducted to find out better and effective techniques. Inside the destiny green communication gadget, cloud computing and the internet of factors will play a vital role and generally tend to become popular. Another important aspect which needs to be considered for future green communication is network security and secures power optimization.  Kusaladharma, Sachitha, and Chintha Tellambura.
