Energy-saving algorithm considering idle light-path prediction in SDM-EON
Published 2019-10-01“…To effectively reduce the energy consumption,blocking rate and crosstalk between adjacent cores in a multi-core fiber for space division multiplexing elastic optical network (SDM-EON),an energy-saving algorithm considering idle light-path prediction was proposed.The extreme learning machine model was used to predict the traffic volume of each light-path in the network.Thus the idle light-path set and the maintenance time threshold of each idle light-path were obtained.Then,the actual maintenance time of the idle light-path was perceived by the prediction algorithm.Finally,in the light-paths where the actual maintenance time do not exceed the minimum maintenance time threshold and the inter-core crosstalk are lower than the crosstalk threshold,the idle light-path with the least loading energy consumption was selected to carry the new traffic.The simulation results show that compared with the traditional energy-saving algorithm,when the SDM-EON crosstalk limitation is satisfied,the proposed algorithm can lead better energy-saving while maintain the blocking rate at levels compatible.…”

Published 2023-09-01“…High-quality home wireless network with large bandwidth, wide coverage, low latency and anti-interference is the key indicator to ensure user experience of fiber to the room (FTTR) Gigabit optical network.Traditional home network equipment mainly adopts single-beam single-polarized antenna design, which has become increasingly unable to meet the needs of high-quality network products under the background of large attenuation and strong interference.Antenna, as an indispensable component to realize conduction energy and air-interface electromagnetic wave transformation, can realize multiple functions by using its design freedom.High gain can reduce the power consumption of the radio frequency (RF) side to achieve the purpose of energy saving, and multi-beam can maintain high-performance network coverage without dead ends.Therefore, designing a multi-beam antenna with small size, high gain and flexible usage is of great value.Following the practical engineering and current academic research, a multi-beam antenna based on spoof surface plasmon polariton (SSPP) technology, covering the 5.1~5.9 GHz frequency band of Wi-Fi, was designed for home network products.Compared with traditional antennas, the test results of the antenna based on SPSS technology show that the coverage performance of the network in weak signal scenarios such as through-wall and cross-layer scenarios is improved greatly.It has great application prospects in increasingly miniaturized home terminal products.…”
