How sleep modes and traffic demands affect the energy efficiency in optical access networks

Abstract

An ever-increasing bandwidth demand is the main driver to investigate next generation optical access (NGOA) networks. These networks, however, do not only have to comply with increasing data rates, they should also meet the societal green agenda. As the access part consumes a major fraction of the energy consumption in today's fiber-to-the-home (FTTH) based telecommunication networks, the energy efficiency of NGOA networks should be an important design parameter. In this paper, we present a detailed evaluation of the energy consumption in different NGOA technologies. Furthermore, we analyze the effects of (1) introducing low power modes (e.g., sleep and doze modes) in the various NGOA technologies and (2) using optimal split ratios adjusted to the traffic demands so that the energy consumption is optimized for the desired quality of service (QoS) level.

Nash Equilibrium of an Energy Saving Strategy with Dual Rate Transmission in Wireless Regional Area Network

“…Considering the traffic dynamics in time domain and space domain, Wu et al put forward a kind of pico BS sleep mode control method oriented heterogeneous wireless networks, which reduces the computational complexity and energy costs [10]. With different access technology of the next generation optical fiber access 2 Wireless Communications and Mobile Computing network, Lannoo et al analyzed the impact of low energy mode (e.g., sleep mode) on the energy efficiency [11].…”
