Thus, 5G security architecture has been built using security-by-design approach which takes into account basic challenges and risks. While such architecture is evidently robust with a number of advanced security measures and mechanisms, increasing diversity of connected devices, services and networking technologies means new and more complex security threats and vulnerabilities Therefore, this paper aims at identifying gaps and potential shortcomings in the existing 5G security framework. On that basis, recommendations for addressing these issues are specified so that secure and trustworthy implementation and operation of 5G networks would be ensured.","PeriodicalId":277553,"journal":{"name":"2022 30th Telecommunications Forum (TELFOR)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128181305","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}

Our evaluation method analyzes the heart rate variability on the MITDB electrocardiogram benchmark database originally sampled to 360 Hz. Then the electrocardiogram records are resampled to 125 Hz, and a new set of heart rate variability parameters are calculated and compared to those calculated on 360 Hz. The analysis performed on time-domain heart rate variability parameters showed that the impact of sampling frequency was large for NN50 and pNN50 parameters (up to a max value of 50%, and mean of 10%), and smaller for SDNN and RMSSD (up to a max value of 10%, and an average of 2%). In conclusion, heart rate variability needs a higher sampling frequency to reveal more precise results.","PeriodicalId":277553,"journal":{"name":"2022 30th Telecommunications Forum (TELFOR)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132903489","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}

One of the greatest challenges with extreme learning machine is finding initial values of weights and biases and determining satisfying number of neurons in the hidden layer for every particular task. To tackle this challenge, which is NP-hard by nature, the arithmetic optimization algorithm was employed. The proposed method was evaluated against ToN IoT Windows 10 dataset for internet of things security for binary classification, and compared to other extreme learning structures evolved by other state-of-the-art metaheuristics under the same experimental conditions.

The mmWave spectrum (30-300 GHz) offers a large portion of unused bandwidth. Among the available mmWave frequency bands, the 60 GHz band is particularly interesting as it is license free and can be used for different applications, ranging from short-range communications to vehicular radars and medium-to-long range wireless links. This paper presents the design, implementation, and evaluation of a mmWave solution in the 60 GHz band that has been carried out within different H2020 projects over past years. The core of the solution is a proprietary field-programmable gate array (FPGA) board with software-defined radio (SDR) capability and a commercial-off-the-shelf (COTS) 60 GHz radio-frequency (RF) beamforming front-end module. It implements a proprietary orthogonal frequency division multiplexing (OFDM) baseband processor and medium-access control (MAC) layer. The designed solution is tested in indoor and outdoor communication scenarios using SDR and real-time mode. The performance measurements in different settings show a data rate of 936 Mb/s and an average round-trip time latency of around 0.25 milliseconds.","PeriodicalId":277553,"journal":{"name":"2022 30th Telecommunications Forum (TELFOR)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123837610","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}
