Abstract

Deployment of femtocells (Home eNode Bs) along with existing macrocells has been drawn considerable attention of mobile industry because of its potential to reduce Operational Expenditure to the operators by offloading traffic from macrocell to femtocells. In this paper, we evaluate the energy efficiency of co-channel deployed macrocell-femtocell networks considering centralized control for HeNBs. We also show the impact of macro-cell power configuration on the energy efficiency. The results show that significant amount of improvement in energy efficiency can be achieved by centrally coordinating macrocell and femtocell networks, according to varying traffic load condition without affecting the Quality of Service requirements of macrocell and femtocell users.
