Greening FiWi access networks

Fiber-Wireless (FiWi) is the hybrid architecture of access networks. Since large amount of energy consumption of internet is due to the access networks, so in this paper Green FiWi (GFiWi) algorithm is proposed that switches the nodes of FiWi access networks to sleep mode in order to reduce energy consumption of FiWi networks not only at the optical but also at wireless part of FiWi. Simulation results showed that there is a slight degradation in the performance despite of the fact that most of the nodes are switched to sleep mode. The energy saving is compared with the state of the art existing algorithm. The GFiWi not only saved significant amount of energy but also achieved improved performance as compared to other existing approaches.
