An optimal energy efficient spectrum management mechanism with multiple thresholds is proposed. The developed mechanism aims to reduce energy consumption in the system by optimizing the spectrum sensing and channel switching, while decreasing the probability of collision, with assuring the reliability thresholds, throughput, and delay. Subsequently an antenna selection sensing (ASS) scheme is used to improve sensing accuracy. The simulation results show that the energy efficiency of the CM2M gateways can be improved significantly.","PeriodicalId":256818,"journal":{"name":"2017 40th International Conference on Telecommunications and Signal Processing (TSP)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127710509","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}

There is usually absence of control system based on each single room. This work proposes a simple, promising, effective and cost-effective regulation system for radiant floor heating. Designed system is based on small wireless sensors placed in every room to measure the temperature and wirelessly send it to the cloud. The data is analyzed and compared with user selected values and appropriate actions are taken by wireless relay unit that controls flow through each heating circuit by thermoelectric actuators. Main benefits of this system is Internet of Things (IoT) solution, which means that all the computing is made in the cloud. Used sensors and relay board can be relatively cheap due to low demands on its computing power. There is not any expensive main unit with display and user interface, because this system can be controlled via cloud from any kind of device (such as notebook, tablet, smart phone etc.).

The flying capacitor enables the converter to generate three-level output voltages, thus resulting in high-quality output waveforms. The new inverter has fewer semiconductor switches and flying capacitors (up to 25% and 50% less, respectively) than the conventional flying capacitor inverter (FCI) that supplies two loads does. The proposed inverter feeds loads through a photovoltaic system. This inverter can be used in a combined on- and off-grid PV fashion. A control method is developed to maintain the desired flying capacitor voltage. The off-grid section of the inverter can operate under different modulation indices and frequencies, independent from on-grid section. The high performance of the inverter is verified through simulation.","PeriodicalId":256818,"journal":{"name":"2017 40th International Conference on Telecommunications and Signal Processing (TSP)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116954302","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}

Therefore, most of the standardization bodies are active in this domain. As a result, several standards for QoE prediction in video streaming systems have been introduced recently. One of them is ITU-T P.1201 with its Amendment n. 2, which has been developed for TCP-based video streaming QoE assesment. The QoE modeling is known as highly complex discipline influenced by many factors, therefore any new standard should be carefully evaluated for its usability for specific applications. Following this, the performance evaluation of ITU-T P.1201 standard as potential QoE assessment tool for online video-streaming services is provided in this paper. The analysis was done based on the subjective experiments performed in laboratory conditions. Moreover, a set of packet-based features appropriate for long-term QoE models independent of future video streaming applications changes are studied to understand their impact on QoE prediction performance. The Pearson correlation and Root Mean Square Error criteria are used to perform a numerical comparison. The most appropriate features' combinations are introduced together with practical conclusions at the end of this paper.","PeriodicalId":256818,"journal":{"name":"2017 40th International Conference on Telecommunications and Signal Processing (TSP)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114164270","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 main advantage of the method is that it may gain adaptation capability for existing fractional-order systems. It essentially contains two loops, which are the inner loop for fractional-order PID (FOPID) control of plant, and the outer loop for implementation of MIT rule for model reference adaptive control. This approach do not modify any parameter of existing closed loop control system, instead it performs input shaping for the closed loop control system so that response of closed loop control system approximates to a desired control response, which is described by the reference model. The method can be useful in fault diagnosis and fault-tolerant control of systems because it may allow maintaining control performance for tolerable system perturbation. The paper presents a simulation study for FOPID and plant models that were obtained by Fractional-order Modeling and Control (FOMCON) toolbox. Results showing the response of proposed system for amplifications type faults are also discussed.","PeriodicalId":256818,"journal":{"name":"2017 40th International Conference on Telecommunications and Signal Processing (TSP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128657659","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}
