Groups of multiplexed users are formed, where each user is equipped with a single antenna, to transmit on the same frequency and time resources. When deployed in a V-MIMO system that resembles the LTE standard parameters, the proposed blind algorithm can obtain accurate estimates of the V-MIMO channels for each active user over every block of transmitted data. In addition, it is necessary to have knowledge of the channels state information to perform the users grouping and frequency allocation (scheduling). According to the LTE standard, sounding reference signals are employed in conjugation with Interleaved-frequency division multiple-access (I-FDMA). By eliminating the need to transmit an entire block of pilot symbols for each active transmitter, this permits for additional bandwidth efficiency in V-MIMO SC-FDMA systems in which multiple users occupy the same set of subcarriers as indicated by the LTE standard. The advantages of employing our proposed blind subspace-based channel estimation algorithm are verified by simulations results over fading channels, which demonstrate its practicality for use in the resulting V-MIMO SC-FDMA scheme with reduced training.","PeriodicalId":378423,"journal":{"name":"2017 IEEE International Conference on Computer and Information Technology (CIT)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125408394","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 main concerns present in VANETs is the localization and tracking of vehicles. This work presents a passive vehicle localization and tracking method based on direction of arrival (DOA) estimation. The proposed method does not rely on external sources of information such as Global Navigation Satellite Systems (GNSS) and can be used to mitigate the possibility of spoofing or to provide a second independent source of position estimation for integrity purposes. The proposed algorithm uses array signal processing techniques to estimate not only the position but also the direction of other vehicles in network. Furthermore, it is a fully passive method and can alleviate the network load since it does not require any location based data exchange and can be performed by any listening vehicle using the signal of any data transmission. A set of numerical simulations is used to validate the proposed method and the results are shown to be more precise than the average accuracy of Global Position System (GPS) receivers.","PeriodicalId":378423,"journal":{"name":"2017 IEEE International Conference on Computer and Information Technology (CIT)","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124724288","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}

Scalable video coding (SVC) is a coding paradigm that allows once-encoded video to be adapted to any desired bitrate or quality level, and thus saves the transmission and storage cost. The state-of-the-art video coding standards H.264 and HEVC incorporate scalable coding as an important extension (H.264 SVC and SHVC). In this study, we comprehensively investigated the rate-distortion and computational-complexity performance of SHVC versus H.264 SVC and wherein four typical scalability configurations were explored. Compared to H.264 SVC, SHVC achieves the same visual quality with approximately one half bitrate, higher encoding complexity and lower decoding complexity. For the selection of spatial scalability and quality scalability under a bitrate constraint, it is suggested to encode a video sequence in higher resolution followed by downsizing to the required resolution instead of direct encoding in lower resolution.","PeriodicalId":378423,"journal":{"name":"2017 IEEE International Conference on Computer and Information Technology (CIT)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130616008","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 SLD aims at determining faulty nodes based on an input syndrome that is generated comparing the outputs from the different nodes. The symmetric comparison diagnosis model assumes that tasks are assigned to pairs of nodes and the results of executing these tasks are compared. Fault nodes are identified based on the agreements and disagreements among the nodes’ outputs. A limit t is assumed on the maximum number of nodes that can fail simultaneously. Various diagnosis algorithms have been developed in the last decades, but the problem of efficiently identifying the set of faulty units of a diagnosable system remained an outstanding research issue. This work introduces a new diagnosis approach for the symmetricbased comparison diagnosis problem using game theory. In this approach, faulty nodes are identified by maximizing the payoffs of all players (nodes). We have tested the new diagnosis approach using randomly generated diagnosable systems under even extreme faulty situations in which the limit t was set close to the number of nodes. The extensive simulations we have conducted proved the efficiency of the new game-theory-based diagnosis algorithm as it succeeded in guessing the fault status all nodes in all faulty situations.","PeriodicalId":378423,"journal":{"name":"2017 IEEE International Conference on Computer and Information Technology (CIT)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132694428","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 biggest impact made on major areas of business activities. Majority of organisations facing cybersecurity adversity and advanced threats suffers from huge financial and reputation loss. The current security technologies, policies and processes are providing necessary capabilities and cybersecurity mechanism to solve cyber threats and risks. However, current solutions are not providing required mechanism for decision making on impact of cybersecurity breaches and fraud. In this paper, we are reporting initial findings and proposing conceptual solution. The paper is aiming to provide a novel model for Cybersecurity Economics and Analysis (CEA). We will contribute to increasing harmonization of European cybersecurity initiatives and reducing fragmented practices of cybersecurity solutions and also helping to reach EU Digital Single Market goal. By introducing Cybersecurity Readiness Level Metrics the project will measure and increase effectiveness of cybersecurity programs, while the cost-benefit framework will help to increase the economic and financial viability, effectiveness and value generation of cybersecurity solutions for organisation's strategic, tactical and operational imperative. The ambition of the research development and innovation (RDI) is to increase and re-establish the trust of the European citizens in European digital environments through practical solutions.","PeriodicalId":378423,"journal":{"name":"2017 IEEE International Conference on Computer and Information Technology (CIT)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124347398","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}
