Architecture design and performance evaluation for future green small cell wireless networks

To meet the global challenge of reducing ICT environment impact and the exponentially growing data traffic, green design of wireless networks is becoming an important issue for cellular network operators. In order to achieve such goal, green network techniques must be applied to change the current network architecture according to future demand. In this paper, we introduce the cellular network with novel architecture which is called fractional separation green (FSG) networks. We investigate the FSG network system from different aspects and show that the proposed architecture can save the cellular network energy consumption by up to 50%.
