Energy efficiency of high QoS heterogeneous wireless communication network (Invited Paper)

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Energy efficiency is becoming a very important issue in modern wireless communication systems. At the same time, maintaining QoS is also critical when trying to reduce power consumption. This paper describes a heterogeneous wireless communication network architecture, and analyses its power consumption and QoS support levels. The result shows that combining cellular communications with femtocells can significantly reduce overall power consumption, depending on the uptake of femtocell usage. Also, QoS remains high when the power consumption drops. The simulation results also suggest that the femtocell implementation rate should be limited under a certain degree, around 60%, in consideration of power efficiency. Finally, indifference curves of power consumption and QoS indicate the optimal femtocell adoption schemes under different requirements.
