Research on energy consumption and bandwidth allocation scheme is the basis for achieving the standard of service and fairness requirements for various traffic classes within the integrated optical-wireless access network which is crucial as the energy consumption issue is increasingly vital nowadays. The access segment of both optical and wireless networks is well-known for its domination over total network power consumption. In this research paper, the full power consumption and energy efficiency of integrated Ethernet Passive Optical Network (EPON) and two wireless technologies, namely, Worldwide Interoperability for Microwave Access (WiMAX) and Long-Term Evolution (LTE) with a unique EPON-based semi-dynamic bandwidth allocation (SD-DBA) is evaluated. A semi-analytical power consumption model is proposed and applied within the simulation model for energy performance evaluation. Furthermore, various parameters that will affect the energy performance like split ratio, femtocell base station (FBS) range, analysis of broadcast elements, and modulation schemes are considered.
The obtained results prove that, the EPON-WiMAX with SD-DBA has better energy efficiency performance compared to EPON-LTE with SD-DBA that offers the best data rates.
