Dynamic elements of the model (tokens) which simulate packets, records of switching and routing tables are supplied with a topology location tag. Switching tags allows us to simulate all the devices of a given topological scheme. The network model is supplied with special measurement subnets which allow fast computation of the network bandwidth, the packet delivery time, and jitter on-fly directly in the process of simulation, without storing intermediate statistical data, for the network performance and QoS evaluation. The advantage of the technique is a fast reconfiguration of models that is very significant for the model-driven design of networks. A case study presents the reenterable model of a Provider Backbone Bridge that comes to replace the Multiprotocol Label Switching technology.","PeriodicalId":229131,"journal":{"name":"2018 26th Telecommunications Forum (TELFOR)","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134474120","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}

However, this improvement can be achieved at the expense of worse bit-error-rate (BER) performance for the low to medium signal-to-noise ratio (SNR) values, while for the high SNRs it outperforms OFDM system in terms of BER. Thus, in this paper, we propose a hybrid system for BER minimization, which assumes implementation of OFDM-IM at high SNR values, and classical OFDM at lower SNR values, all based on the known channel characteristics.","PeriodicalId":229131,"journal":{"name":"2018 26th Telecommunications Forum (TELFOR)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116451293","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}

Generally speaking, the shape of the outdoor noise angular energy distribution is not known. Therefore, it is necessary to determine and analyze this distribution in real urban environments. This paper presents the methodology for experimental determination of the incident energy angular distribution of the outdoor noise on the building envelope. The method is based on the sound source localization using an optimized microphone array with 24 microphones and utilizing the algorithms for space-time signal processing. The methodology is applied in several characteristic terrain configurations in urban environments in order to observe the differences in the shapes of angular distributions. By using known building material characteristics and experimentally obtained shapes of the angular distributions, a prediction was performed for the in-situ value of the sound reduction index of the most common façade elements in urban environments. Such method enables the observation of differences of in-situ values of the same partition when it is placed in urban environments with different terrain configurations.","PeriodicalId":229131,"journal":{"name":"2018 26th Telecommunications Forum (TELFOR)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128543593","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}

In recent years a lot of effort is focused on developing automatic detection of cyber-attacks using data mining techniques on the data generated from network traffic. In this paper a methodology for automatic detection of cyber-attacks is proposed. To improve the performance, the network traffic data is first preprocessed by filtering and combining features from the original data. The new augmented and refined data is then used to build a classification model that can discriminate between normal network traffic and cyber-attacks. Experimental scenarios are set up to evaluate the effect of preprocessing on the final performance, and additionally to provide insight on possible recommendations in terms of a most suitable classification algorithm. The obtained results indicate performance improvement with data preprocessing. All used classification algorithms provide very high AUC of over 0.95 which attests that the proposed methodology is highly promising for the development and improvement of current and future cyber-attacks detection systems.","PeriodicalId":229131,"journal":{"name":"2018 26th Telecommunications Forum (TELFOR)","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116587038","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}
