Optimization of sleep period in watchful sleep mode for power-efficient passive optical networks
TLDR
This paper formulated the system performances of the watchful sleep mode in terms of the power consumption and the state transition delay by using the state probability based on arrival traffic profile and compared it with the cyclic sleep mode under the same conditions.Abstract:
The energy consumption in data communication networks has drawn global attention due to the ever-increasing of broadband users. In this paper, we formulated the system performances of the watchful sleep mode in terms of the power consumption and the state transition delay by using the state probability based on arrival traffic profile. And we compared the performances of the watchful sleep mode with the cyclic sleep mode under the same conditions. For above two conflicting performance indexes, the Sleep period is a key factor. Thus we designed the Cost function to determine the balanced Sleep periods for the certain requirements of power saving and state transition delay. And the simulation results verified the balanced Sleep period can greatly improves the system performances.read more

TL;DR: In this article, a sleep aware dynamic bandwidth and wavelength assignment (DWBA) scheme for TWDM PON is presented to coordinate with cyclic sleep mode (CSM), which only assign bandwidth to active ONUs during the guaranteed phase, surplus phase and excess phase allocation phases which minimizes the bandwidth waste and the bandwidth lost at the ONU end.

Quantitative model checking for assessing the energy impact of a MITM attack on EPONs
TL;DR: This paper uses formal analysis to quantitatively assess the impact of a fake OLT attacking an EPON energy‐efficiency mechanism and shows that a MITM attack increases the energy expenditure, since it enforces the Optical Network Units (ONUs) to stay in the active mode even in cases of none network traffic.
