A number of open challenges affect practical deployments, such as simultaneous use of multiple technologies, intelligent coordination of a subset of nodes, coexistence of different technologies using the same spectrum, efficient management of (simultaneously used) heterogeneous radio links, etc. This paper will consider Semantic Technology (ST), as a promising approach to coordination in such complex wireless infrastructures, especially in cases where interference models are not well understood. A Neural Network (NN) will be used for the network state estimation and ST for reasoning about required actions. It is based on semantic data sets mining such that coordination decisions may be driven by predictions instead of using physical spectrum sensing devices. ST facilitates reasoning about coordination, application priority, frequency selection and dynamic spectrum access. Because of capability of the NN to solve regression and classification problems, potentially problematic network states could be proactively avoided instead of reactively corrected particularly in priority critical applications.","PeriodicalId":422501,"journal":{"name":"2017 25th Telecommunication Forum (TELFOR)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121163900","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}

Indoor propagation environment is quite demanding, with high influence of multipath and through-obstacle signal propagation, such conditions have negative impact on the indoor positioning. NLOS (non-line of sight) propagation is especially problematic and should be dealt with. In the paper a novel method for NLOS mitigation in UWB localization system is presented.

Challenges such as data security, privacy protection, data access, storage model, lack of standards and service interoperability were set up almost ten years ago. This paper presents a part of the research on the cloud security systems at the infrastructure layer and its sublayer — network layer. To analyze and protect cloud systems we need storage and machines with extra features. Due to these needs, we used new technologies from Microsoft to suggest framework of host and network based systems for cloud intrusion detection and prevention system (CIDPS). The purpose of this research is to recommend use of the architecture for the detection network anomalies and protection of large amounts of data and traffic generated by cloud systems.","PeriodicalId":422501,"journal":{"name":"2017 25th Telecommunication Forum (TELFOR)","volume":"52 52","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113933348","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}

This paper describes a configurable system for handling X509 certificates, which has been used within the practical project at the Computer Security course. The system provides the ability to generate, sign, and manipulate X509 certificates. The system was implemented in such a way that the graphical user interface (GUI) is completely separated from the logic, which relaxes the students from GUI programming and enables them to concentrate on programming the part related to the certificates. The system has been successfully used at the course in the previous school year.","PeriodicalId":422501,"journal":{"name":"2017 25th Telecommunication Forum (TELFOR)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132535854","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}

Resources in the robotics field are limited for a common user to access and demand deep knowledge of robot-specific programming paradigms. For these reasons, it is not often possible for inexperience students to become familiar with programming and control of complex robotic systems in a practical manner. This paper presents a new method for remote robot programming, control and monitoring independently of user's location by using smart phones, which focuses on ease-of-use, intuitiveness and minimizing the users' cognitive load while maintains abilities for accurately and efficiently programming and control. With the application of the proposed solution in education, the ability to work with inaccessible robotics systems and equipment through the intuitive virtual laboratories, independent on the user's location, is provided and thereby the quality of gaining knowledge is significantly improved.","PeriodicalId":422501,"journal":{"name":"2017 25th Telecommunication Forum (TELFOR)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130203855","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}
