A Distributed Power-Saving Topology Management Scheme in Green Internet

In a context of explosive development in Internet scale and excessive underutilization of a large number of network elements, the power consumption issues of the current Internet have become hot subjects extensively concerned by ICT (Information and Communication Technology) sector and research institutions in recent years, which even further lead to the severe economic issues and intractable environmental issues. On the basis of above circumstances, a Distributed Power-saving Topology Management Scheme (DPTMS) is devised to achieve power saving for current Internet in the paper. After introducing the network model and power model, we describe the design of DPTMS including four modules: traffic prediction module, information awareness model, distributed topology decision-making module and sleeping control module. In the simulation and evaluation, DPTMS is compared with GRiDA as for network power consumption and network performance, which shows it is feasible and effective for a power-saving topology management.
