Dynamic topology based network energy-saving mechanism

With the rapid development of networks and constant renewal of network devices, the energy problem of network attracts more and more attention. High energy consumption and low efficiency have become an important factor of obstructing the network further development. In this paper, a dynamic topology based network energy-saving mechanism is proposed. It consists of three parts: data acquisition module, traffic prediction module and information decision module. The data acquisition module is responsible for collecting the network topology, the traffic and the routers´ load. It is the basis of the other two parts. The traffic prediction module is responsible for forecasting the traffic of network in real-time. And it also sends the result to the decision module. The information decision module will process information send by the collection module and the traffic prediction to make a good decision, which let some route to be sleeping or wake-up state. This mechanism will save network energy effectively without affecting the quality of network service. The simulation and performance evaluation show that the proposed algorithm has better performance.
