These days there is a clear trend toward extending the reach of passive optical networks to
cover large geographical areas, which enables reduction of the number of central offices …

Energy usage in our networks is increasing rapidly; and to conserve energy, progress has
been made in designing energy-efficient passive optical networks, which are being widely …

In order to ensure fairness of each optical networks unit (ONU) in access network and meet
quality of service (QoS) requirements of differentiated service such as voice, video and data …

In modern, competitive, and dynamic access networks the underlying bandwidth distribution
mechanism has to be capable of understanding user requirements, meeting stringent quality …

We propose an energy-efficient orthogonal frequency division multiplexing-based passive
optical network (OFDM-PON) using adaptive sleep-mode control and dynamic bandwidth …

As concerns about energy consumption grow, the power consumption of the EPON
becomes a matter of increasing importance. In respect of energy efficiency, the current …

This paper proposes a dynamic bandwidth allocation algorithm that improves the network
performance and bandwidth sharing efficiency in the upstream channels of a hybrid passive …

Passive Optical Networks (PONs) are widely adopted as the last-mile technology due to the
large bandwidth capacity it provides to end users. In addition, PON is viewed as a green …

A novel fine scheduling algorithm is introduced for upstream bandwidth allocation in an
Ethernet-based passive optical network. This scheduling algorithm consists of an inter …

Online scheduling algorithms incur no idle time problem but with less bandwidth efficiency,
while offline scheduling algorithms focus on bandwidth efficiency but with idle time …
