Abstract |
|
|
| Energy consumption of ICT (Information and communication Technology) is emerging with tremendous challenges which are prevailing throughout the world. One among them is energy conservation which plays a vital role in telecommunication networks. The access network, which is the last mile of telecommunication network plays the dominant role of energy consumption. So, effective strategies to reduce energy consumption in access systems can foremost savings in the Internet energy consumption. We set a goal to decrease energy consumption in access networks without diluting the Quality of Service (QoS). To develop the “Green Hybrid Wireless Optical Broadband Access Network” focusing on a feasible implementation of a sleep mode in Optical Network Unit(ONU) at passive optical networks (PON). Wireless Optical Broad Band Access Network(WOBAN) is a novel hybrid access concept combining the high capacity Optical backhaul (PON) with a wireless front end, thus providing very high throughput in a cost-effective manner. We propose a strategy to improve the energy efficiency of WOBAN. The proposal consists of increasing the number of sleep cycles to improve energy conservation in ONUs with a fast wakeup capability. It can increase the number of sleep cycles. To implement this proposal, an algorithm is designed to improve the energy efficiency while ensuring QoS, keeping delays under a threshold and setting the ONU in sleep mode
