It builds on the integration of (i) intelligent sensor devices capable of registering specific behavioural indicators, (ii) mobile personal devices, which serve primarily as data concentrators, information gateways and displays, and (iii) remote storage and processing resources, where health data are aggregated for advanced statistical processing. This architecture builds on the principles of distributed computing and resource storing at the network edge, yet it also relies on methods and technologies typically used in cloud-computing applications and 5G technology. More importantly, however, it is capable to sense the communication context and providing a seamless transition between environments with dissimilar communication capacities and allowing for graceful degradation of functionality in case of a shortage of battery or local storage resources. The last is expected to provide numerous benefits that are expected to facilitate the pervasiveness of eHealth monitoring solutions.","PeriodicalId":293631,"journal":{"name":"2021 29th National Conference with International Participation (TELECOM)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124606956","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 aim of the work is to make a comparison between the two virtual IP networks and to check which of the two topologies will have an improvement in the performance of the virtual IP network.

These items can be books, movies, restaurants, and things to which individuals have different preferences. These systems help users to decide on the appropriate items and facilitate the task of finding a favorite collection items. The aim of this project is to create a system of recommendation based on textual documents, exactly will create an application making the recommendation of the mentor and the committee automatically based on the proposal of the topic and documents that are in the archive database. The algorithms that we have used are Rake which used to extract the keyword through textual documents and Leveshtein distance algorithm. This algorithm used to derive the similarity between documents based on keyword extraction that have the textual documents. Initially, the student must apply the system to be registered on the database, after applying the system extract the keywords from the document applied and compares with the proposals of the topics that are in the archive of data base and in the end brings us automatically appropriate mentor for the topic and the commission.","PeriodicalId":293631,"journal":{"name":"2021 29th National Conference with International Participation (TELECOM)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125789077","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}

Channel identification is a great challenge for cognitive devices, so channel activity plays an important role in spectrum management decisions. Dimension reduction with Principal Component Analysis (PCA) and various clustering methods (agglomerative, K-means and K-medoids) are used to reduce the hardware and software requirements while maintaining and improving detection accuracy. The goal of the proposed analysis is to discover the optimal parameters for data processing in spectrum hole allocation for cognitive radio systems by using preprocessing and cluster analysis.","PeriodicalId":293631,"journal":{"name":"2021 29th National Conference with International Participation (TELECOM)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124758669","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 active approach that an intruder can use to improve its downlink channel and intercept the private information of other users is initiating a pilot contamination attack (PCA). In this paper, two methods for the detection of PCA based on analyses of the constellation diagram are studied – 2-N-PSK and Shifted 2-N-PSK. Their performance is evaluated through two crucial parameters, namely the PCA detection probability and PCA false alarm probability, both investigated in scenarios with different number of antenna elements at the base station. Since the Shifted 2-N-PSK detection method improves the detection probability of 2-N-PSK by altered constellations, the paper proposes a low-complexity algorithm to compute simultaneously the shift values at the transmitter and receiver.","PeriodicalId":293631,"journal":{"name":"2021 29th National Conference with International Participation (TELECOM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130057698","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}
