Analysis of integrated networks: super-EPON-WiMAX and super-EPON-LTE, and power consumption modeling

Research on energy consumption and bandwidth allocation schemes is crucial for meeting the service standards and fairness requirements of different traffic classes in an integrated optical-wireless access network. This is especially important as energy consumption becomes increasingly significant in today's context. The access segment of both optical and wireless networks is well-known for its high-power consumption. In this research paper, we evaluate the total power consumption and energy efficiency of an integrated Super Ethernet Passive Optical Network (Super-EPON) and two wireless technologies: Worldwide Interoperability for Microwave Access (WiMAX) and Long-Term Evolution (LTE). Our focus is specifically on an EPON-based semi-dynamic bandwidth allocation (SD-DBA) scheme. To assess energy performance, we propose a semi-analytical power consumption model and incorporate it into a simulation model. We also consider various parameters that can impact energy performance, such as split ratio, range of femtocell base stations (FBS), analysis of broadcast elements, and modulation schemes. The results demonstrate that Super-EPON-WiMAX with SD-DBA exhibits superior energy efficiency compared to EPON-LTE with SD-DBA. Specifically, Super-EPON-WiMAX offers the highest data rates with a 13% increase in splitting ratio, a 3.9% increase in FBS range, and an 8.8% increase in broadcast factor.
