Without having to rely on the bandwidth expansion of optical waveguides or modulation level efficiency, one of the ways to increase spectral efficiency of a network is by the optimal utilization of already existing resources. Since the resource management can be improved when the future traffic is known beforehand, in this work, we investigate the ability of recurrent neural networks (RNN) with long short-term memory (LSTM) to realize traffic matrix prediction based on previous traffic history of the computer network. Real traffic data has been used to train the RNN, from an anonymized dataset containing the traffic history of the Abilene and GEANT optical networks from the years 2004-2005 and test the viability of LSTM RNN models for proper traffic prediction. The proposed models achieved a mean square error of 0.0026 for the Abilene and 0.00058 for the GEANT network.","PeriodicalId":175865,"journal":{"name":"2019 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference (IMOC)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132959315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To improve the performance of distributed sensors in optical fibers, we will present in this paper an alternative approach to performing their calibration. The proposed calibration method consists of an algorithm that represents the sensor signal by a sum of Gaussian functions and then determines the new Gaussian parameters for the signal to be corrected. Such methodology allows obtaining different spatial resolutions according to the precision range required. For example, spatial resolutions of 29.82 cm and 1.8 cm were obtained for hot spots of 50 cm and 3 cm, respectively.","PeriodicalId":175865,"journal":{"name":"2019 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference (IMOC)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126031611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The antenna and FSS have an isosceles trapezium geometry. Three different versions of an antenna are created. For each version, the S-parameters S11 and S21 were simulated with the software CST Microwave Studio®. Then, one of the three trapezoid antennas is simulated with an FSS. These two devices, antenna and FSS, were manufactured and had the S11 and S21 parameters measured at the laboratory. The resonance frequency obtained for the trapezium FSS was equal to 2.27 GHz for $alpha$ equal to 0 °, 2.70 GHz for $alpha$ equal to 15 ° and 3.12 GHz for $alpha$ equal to 30 °. The simulated antenna gain increased when the FSS is used as superstrate. Without the presence of the FSS, a maximum gain of approximately 1.50 db occurs at 2.20 GHz, when using the FSS as superstrate, the gain increases to approximately 5.25 db.
