Most common transceiver imperfections are oscillator phase noise, I/Q imbalance, amplifier non-linearities, self-interference in a full duplex mode, etc. In this paper, the performance of a dual-hop decode-and-forward underlay cognitive radio network with transceiver hardware impairments and interference power constraints is studied. Closed-form expressions for the exact outage probability (OP) over independent and non-identically distributed Nakagami-m fading channels are presented. More, asymptotic analysis of the OP at high signal-to-noise-distortion ratio values is analyzed. A relation between the hardware impairment level and the transmission rate is investigated using numerical simulations. Hardware impairment level is evaluated for various fading severity parameters of the channel when OP and source power are given. Monte Carlo simulations results corroborate the analytical ones.","PeriodicalId":250788,"journal":{"name":"2018 International Conference on Computing and Network Communications (CoCoNet)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115038276","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 capability of ANN to perform at highspeed has been proven to be very useful for various large scale problems. One of the simple ANN models is perceptron. Since the perceptron is the basic form of a neural network, the efficient implementation of an activation functions is required to build the neural network on hardware. As various works introduce the design of sigmoid and tangent activation functions, most of the other activation functions remain an open research problem. This paper describes the design of the perception circuit with the linear activation function based on operational amplifier for memristive crossbar based neural networks. Additionally, the variation of performance with temperature and noise noise analysis of the circuit are presented.","PeriodicalId":250788,"journal":{"name":"2018 International Conference on Computing and Network Communications (CoCoNet)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123271783","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, WSNs have finite resources. The Wireless sensors have a limited battery life, which in turn affects the life of the entire network. Energy dissipation is the key issue. Sensors use considerable energy for communicating amongst themselves. The distance between the sensors is a major cause for this energy dissipation. Therefore, reducing the communication distance can greatly benefit the network life. To preserve energy and minimize the transmission distance, clustering is one solution. Data communication from one sensor to other at a large scale consumes more energy limited transmissions are possible through clustering. Load balancing is achieved in clustering through data aggregation and this helps to prolong the lifetime of network. This paper proposes a fitness function that can be used to form clusters with energy consideration. Particle swarm optimization (PSO) and Social group optimization (SGO) are implemented with the proposed fitness equation and their performances are studied.","PeriodicalId":250788,"journal":{"name":"2018 International Conference on Computing and Network Communications (CoCoNet)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115247028","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}

Recent approaches and challenges for service restoration are compared and analyzed. Service restoration is a multi-constraint, multi-objective, combinatorial, non-linear optimization problem. Its main aim is to maximize the number of priority loads restored, while minimizing the number of switching operations, within the shortest time interval. This paper introduces Hybrid Multi-Agent System Approach for service restoration, which uses Distributed Generators (DG) and Electric Vehicles (EVs). EVs are basically batteries, which are charged at low-load conditions and transmit required amount of energy at peak-load conditions back to the grid. Before applying this system in real cases, optimal positions of DGs must be found. In order to do so OpenDSS Distribution network simulator was used for IEEE 123 and 30 Bus System. After that, R&M algorithm was developed and implemented under IEEE 30 Bus System. The main goal of this algorithm is to determine the most optimal island ranges according to the given objective functions and constraints. Proposed R&M algorithm demonstrated quite promising results as it fulfill all preset requirements.","PeriodicalId":250788,"journal":{"name":"2018 International Conference on Computing and Network Communications (CoCoNet)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130203589","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 are several digital, mixed signal and analog implementations of a sigmoid function; however the existing sigmoid circuits limit the scalability of ANN due to large on-chip area and high power consumption. In this paper, we address this issue and propose analog memristor-based sigmoid activation function implementation. The CMOS components of conventional gain adjustable voltage-mode sigmoid circuit are replaced with memristive element. The behavior of the modified sigmoid is simulated in SPICE and compared with the existing CMOS design. The simulation results show that memristor based sigmoid allow to reduce on-chip area and power dissipation by 20% and 5%, respectively. The gain of the sigmoid is increased by 20%, while the processing time remains unchanged.","PeriodicalId":250788,"journal":{"name":"2018 International Conference on Computing and Network Communications (CoCoNet)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125387410","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}

It combines traditional realization of a non-linear resistor in Chua's chaotic oscillator with a promising memristive circuitry. This mixed implementation connects old research works that were focused on diodes with relatively new research papers that are, now, concentrated on memristors. As a result, a more reliable chaotic circuit with an HP memristor is obtained that could be used as a source of randomness. Dynamic behavior of the circuit is studied by obtaining FFT analysis, different chaotic attractors and Lyapunov exponent spectrum. The results show that the addition of a memristor enhances the chaotic behavior of the circuit while reducing the power consumption by 1.95%.","PeriodicalId":250788,"journal":{"name":"2018 International Conference on Computing and Network Communications (CoCoNet)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121066515","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, on-line or online diagnosis is more preferable and faster than off-line monitoring procedure.

In this paper, we presented a router duty mode, which reduces the overall power consumption of the wireless network. The router's duty mode is a process of sequentially switching nodes from the role of routers to the role of sensor nodes.

At the same time, renewable technologies have become cheaper and more accessible for the general public. This spurred the popularity of rooftop solar panels and the development of residential energy management systems. Nowadays, some households are able to generate more power that they can use at the moment. More efficient ways of energy management are needed to sell unused energy back to the utility or to store it for later use. In this paper, we develop an analytical model of residential energy management system (EMS) with renewable energy supply such as solar energy and investigate the feasibility of energy storage system (ESS) deployment in residential EMS for energy cost reduction. Simulations with real-life data show that residential EMS with ESS can effectively reduce the energy cost in a variety of electric utility pricing schemes.","PeriodicalId":250788,"journal":{"name":"2018 International Conference on Computing and Network Communications (CoCoNet)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129526070","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}
