A Dynamic Topology Management Mechanism in Green Internet

In recent years, the rapid development of the Internet has provided people with more and more convenience. However, meanwhile a tremendous energy consumption problem and a low energy efficiency problem in the networks still exist. With the continuous expansion of the network scale, these problems are increasingly more severe. In order to achieve the "green" goal in the paper, first a networking model for green backbone network is built, then an innovative node structure and an innovative link structure are designed, furthermore, constitution of energy consumption in network device is analyzed, and a power model of the network device is set up, then according to the power-law principle, the values of network elements are evaluated from the three aspects of resource utilization rate, the impact degree on robustness of the network topology and the impact degree on communication quality, finally, a dynamic topology management mechanism in green Internet is proposed. Applicability and validity of the innovative mechanism with respect to energy saving and topology management are verified via prototype simulation and performance evaluation.
