  • Performance comparison of Modified BPSK-OFDM and QFSK-OFDM in PLC Channel
           noise

    • Authors: Abiola G Bolaji, Thokozani Shongwe
      Pages: 599 - 605
      Abstract: The article describes and compares two OFDM
      based communications schemes for reducing the effects of the
      combination of Narrowband Interference (NBI) and Impulsive
      Noise (IN), which are noise types typical in Power Line Communication
      (PLC). The two schemes are Modified BPSK-OFDM
      (called MBPSK, for brevity) and QFSK-OFDM (called QFSK,
      for brevity), which are non-conventional OFDM schemes. We
      give a description of the two schemes, showing how they are
      derived and also show their similarities and eventually compare
      their performances. Performance simulation results, in terms
      of bit error rate, are given to compare the systems under the
      effect of IN and NBI. The popular Middleton Class A model
      is used for modelling IN. The results show that MBPSK scheme
      outperforms the QFSK scheme in terms of minimum distance,
      and hence in terms of bit error probability when no preprocessing
      is performed. However, under clipping/nulling, both schemes
      eventually reach the bit error rate floor.

  • A Novel Design of U-Slotted SIW Based Wideband Antenna

    • Authors: Subuh Pramono, Eddy Triyono, Budi Basuki Subagio
      Pages: 613 - 618
      Abstract: In this paper, we proposed a novel design of U-slotted SIW antenna. Our antenna design is aimed to cover upper K-band and lower Ka-band spectrums, specifically from 24 GHz to 32 GHz. It has a compact square size of 5.2 x 5.2 mm2. We use a rectangular truncated corner to optimize the square radiator. The optimized rectangular truncated corner size of 2 x 0.8 mm2 gives an impedance bandwidth of 7.87 GHz. SIW cavity is constructed by using multiple metallic via-holes which are drilled in a dielectric substrate establishing. Next optimization, applying the U-shaped slot and SIW structure yield a wider impedance bandwidth of 8.89 GHz, there is about 1.02 GHz of impedance bandwidth enhancement. In addition, the SIW structure gives a higher gain of 7.63 dB and decreases the sidelobe level of -12.1 dB. Implementation of the SIW structure significantly decreases the size of antenna while keeping the antenna parameter’s performances.

  • Modeling of Distributed Ledger Deployment View

    • Authors: Tomasz Górski, Jakub Bednarski
      Pages: 619 - 625
      Abstract: The Distributed Ledger Technology (DLT) is a peer-to-peer model of sharing data among collaborating parties in a decentralized manner. An example of DLT is a blockchain where data form blocks in an append-only chain. Software architecture description usually comprises multiple views. The paper concentrates on the Deployment view of the DLT solution within the 1+5 architectural views model. The authors have proposed Unified Modeling Language (UML) extensibility mechanisms to describe the needed additional semantic notation to model deployment details. The paper covers both the network and node levels. The proposed stereotypes and tagged values have enriched the UML Deployment diagram. We have gathered those modeling elements in dedicated UML Profile for Distributed Ledger Deployment. We have applied the profile to model the Deployment view of a renewable energy management system that uses the R3Cordaframework. The system records information about inbound and outbound energy to/from a renewable energy grid.

  • Integer Matrix Keys for Secure Data Aggregation in Clustered Wireless
           Sensor Networks

    • Authors: G. Chethana, K.V. Padmaja
      Pages: 637 - 645
      Abstract: Providing Privacy and security for aggregated data in wireless sensor networks has drawn the attention of practicing engineers and researchers globally. Several cryptographic methods have been already proposed to solve security and data integrity problems for aggregated data. Matrix cryptography is a better option for creating secure encryption/decryption algorithms to counter quantum attack. However, these algorithms have higher computational cost and increased communication overhead. Hence, a new technique of loss-less secure data aggregation in Clustered Wireless Sensor Networks is presented. The proposed method uses integer matrices as keys for data security and data integrity. Matrix operations are carried out in finite field Zp. Loss-less secure data aggregation is extended for homomorphic summation while the cipher text expansion ratio is kept substantially low. The proposed algorithm has inbuilt fast and efficient signature verification facility. The execution time of our signature verification mechanism is found to be approximately 50 percent less compared to a couple of standard existing signature verification schemes.

  • Differential cryptanalysis of new Qamal encryption algorithm

    • Authors: Kunbolat Algazy, Ludmila Babenko, Rustem Biyashev, Evgeniya Ishchukova, Ryszard Romaniuk, Nursulu Kapalova, Andrzej Smolarz, Saule Nysynbaeva
      Pages: 647 - 653
      Abstract: Currently, the Republic of Kazakhstan is developing a new standard for symmetric data encryption. One of the candidates for the role of the standard is the Qamal encryption algorithm developed by the Institute of Information and Computer Technologies (Almaty, Republic of Kazakhstan). The article describes the algorithm. Differential properties of the main operations that make up the Qamal cypher are considered in the questions of stability. We have shown that for a version with a 128-bit data block and the same secret key size for three rounds of encryption it is difficult to find the right pairs of texts with a probability of 2–120, which makes differential cryptanalysis not applicable to the Qamal cypher

  • A High-Accuracy of Transmission Line Faults (TLFs) Classification based on
           Convolutional Neural Network

    • Authors: Syifaul Fuada, Hasbi Ash Shiddieqy, Trio Adiono
      Pages: 655 - 664
      Abstract: To improve power system reliability, a protection mechanism is highly needed. Early detection can be used to prevent failures in the power transmission line (TL). A classification system method is widely used to protect against false detection as well as assist the decision analysis. Each TL signal has a continuous pattern in which it can be detected and classified by the conventional methods, i.e., wavelet feature extraction and artificial neural network (ANN). However, the accuracy resulting from these mentioned models is relatively low. To overcome this issue, we propose a machine learning-based on Convolutional Neural Network (CNN) for the transmission line faults (TLFs) application. CNN is more suitable for pattern recognition compared to conventional ANN and ANN with Discrete Wavelet Transform (DWT) feature extraction. In this work, we first simulate our proposed model by using Simulink® and Matlab®. This simulation generates a fault signal dataset, which is divided into 45.738 data training and 4.752 data tests. Later, we design the number of machine learning classifiers. Each model classifier is trained by exposing it to the same dataset. The CNN design, with raw input, is determined as an optimal output model from the training process with 100% accuracy.

  • ARPNetSteg: Network Steganography using Address Resolution Protocol

    • Authors: Punam Bedi, Arti Dua
      Pages: 671 - 677
      Abstract: Steganography is a technique that allows hidden transfer of data using some media such as Image, Audio, Video, Network Protocol or a Document, without its existence getting noticed. Over the past few years, a lot of research has been done in the field of Image, Video and Audio Steganography but very little work has been done in Network Steganography. A Network Steganography technique hides data in a Network Data Unit, i.e., a Network Protocol Packet. In this paper we present an algorithm ARPNetSteg that implements Network Steganography using the Address resolution protocol. Our technique is a robust technique that can transfer 44 bits of covert data per ARP reply packet.

  • Policies for Transmit Power Control in the Conditions of Jamming in
           Clustered Wireless System

    • Authors: Jarosław Tadeusz Michalak
      Pages: 679 - 685
      Abstract: This article presents a consistent solution of Transmit Power Control in centralized (clustered) wireless network with and without jamming. Depending on the policy assumed, solutions are applied to minimize the power used in a system or to satisfy expected Quality of Service. Because of specific nature of the system there is no optimal solution which can be applied in practice. Correctness and effectiveness of four proposed Power Control algorithms was presented in the form of computer simulation results in which the system capacity, mean power used and the number of successful links were described.

  • Cryptographic protection for military radio communications

    • Authors: Robert Białas, Marcin Grzonkowski, Robert Wicik
      Pages: 687 - 693
      Abstract: Protecting the confidentiality, integrity and availability of information is very important in any telecommunications system. Information protection requires use of necessary physical, personal, information and communication technologies and above all – electromagnetic and cryptographic security measures. Equipment and tools for cryptographic protection should be examined and assessed in terms of resistance to known threats. Additional requirements are put on information protection for radio communication, especially military, where radio transmission is characterized by uncertainty of establishing and maintaining connections, bit rates are relatively low, often without full duplex. All this has an impact on the methods of cryptographic synchronization and implementation of cryptographic functions. A different approach to information protection is required by classic narrowband radio communications, a different one in time-division multi-access modes, and another one in broadband packet data transmission. Systems designed for information protection in radio communications implement appropriate operating modes of operation for cryptographic algorithms and protocols. Latest threats from quantum computers pose new challenges, especially in systems using public-key cryptography, because there are algorithms that can be used to attack these schemes with polynomial complexity.

  • ZA-APA with Adaptive Zero Attractor Controller for Variable Sparsity
           Environment

    • Authors: S. Radhika, A. Chandrasekar, S. Nirmalraj
      Pages: 695 - 700
      Abstract: The zero attraction affine projection algorithm (ZA-APA) achieves better performance in terms of convergence rate and steady state error than standard APA when the system is sparse. It uses l1 norm penalty to exploit sparsity of the channel. The performance of ZA-APA depends on the value of zero attractor controller. Moreover a fixed attractor controller is not suitable for varying sparsity environment. This paper proposes an optimal adaptive zero attractor controller based on Mean Square Deviation (MSD) error to work in variable sparsity environment. Experiments were conducted to prove the suitability of the proposed algorithm for identification of unknown variable sparse system.

      Abstract: W polskim górnictwie węgla sieci dystrybucyjne średniego napięcia działają z izolowanym punktem neutralnym. Przekładniki prądowe o zerowej sekwencji są podstawowymi czujnikami, które generują sygnały wejściowe dla przekaźników zabezpieczających przed zwarciem doziemnym. W literaturze problem analizy odpowiedzi częstotliwościowej różnych typów przekładników prądowych był wielokrotnie badany, np. [1] [2], ale jak dotąd nie dotyczy przekładników prądowych o zerowej sekwencji. W ramach pracy przetestowano dwa typy przekładników prądowych o zerowej sekwencji w zakresie od 0,1 Hz do 100 kHz. Przeanalizowano zarówno zmianę stosunku prądu, jak i przesunięcie kątowe między prądem wtórnym transformatora a całkowitym prądem pierwotnym.

  • A constrained maximum available frequency slots on path based online
           routing and spectrum allocation for dynamic traffic in elastic optical
           networks

    • Authors: Akhtar Nawaz Khan
      Pages: 707 - 714
      Abstract: Elastic optical networking is a potential candidate to support dynamic traffic with heterogeneous data rates and variable bandwidth requirements with the support of the optical orthogonal frequency division multiplexing technology (OOFDM). During the dynamic network operation, lightpath arrives and departs frequently and the network status updates accordingly. Fixed routing and alternate routing algorithms do not tune according to the current network status which are computed offline. Therefore, offline algorithms greedily use resources with an objective to compute shortest possible paths and results in high blocking probability during dynamic network operation. In this paper, adaptive routing algorithms are proposed for shortest path routing as well as alternate path routing which make routing decision based on the maximum idle frequency slots (FS) available on different paths. The proposed algorithms select an underutilized path between different choices with maximum idle FS and efficiently avoids utilizing a congested path. The proposed routing algorithms are compared with offline routing algorithms as well as an existing adaptive routing algorithm in different network scenarios. It has been shown that the proposed algorithms efficiently improve network performance in terms of FS utilization and blocking probability during dynamic network operation.

  • Design of Network Traffic Congestion Controller with PI AQM Based on ITAE
           Index

    • Authors: Misbahul Fajri, Kalamullah Ramli
      Pages: 715 - 721
      Abstract: Establishing the proper values of controller parameters is the most important thing to design in active queue management (AQM) for achieving excellent performance in handling network congestion. For example, the first well known AQM, the random early detection (RED) method, has a lack of proper parameter values to perform under most the network conditions. This paper applies a Nelder-Mead simplex method based on the integral of time-weighted absolute error (ITAE) for a proportional integral (PI) controller using active queue management (AQM). A TCP flow and PI AQM system were analyzed with a control theory approach. A numerical optimization algorithm based on the ITAE index was run with Matlab/Simulink tools to find the controller parameters with PI tuned by Hollot (PI) as initial parameter input. Compared with PI and PI tuned by Ustebay (PIU) via experimental simulation in Network Simulator Version 2 (NS2) in five scenario network conditions, our proposed method was more robust. It provided stable performance to handle congestion in a dynamic network.

  • Minimizing Delay Using New Dynamic Blocking Expanding Ring Search
           Technique for Ad hoc Networks

    • Authors: Kavita Prashant Mhatre, Uday Pandit Khot
      Pages: 723 - 728
      Abstract: Energy and latency are the significant Quality of Service parameters of ad hoc networks. Lower latency and Limited energy expenditure of nodes in the ad hoc network contributes to a prolonged lifetime of the network. Reactive protocols determine the route to the destination using a route discovery process which results in increased delay and increased energy expenditure. This paper proposes a new technique of route discovery,Dynamic Blocking Expanded Ring Search (DBERS) which minimizes time delay and energy required for route discovery process. DBERS reduces energy expenditure and time delay occurring in the existing route discovery techniques of reactive protocols. The performance of DBERS is simulated with various network topologies by considering a different number of hop lengths. The analytical results of DBERS are validated through conduction of extensive experiments by simulations that consider topologies with varying hop lengths.The analytical and simulated results of DBERS are evaluated and compared with widely used route discovery techniques such as BERS, BERS+. The comparison of results demonstrates that DBERS provides substantial improvement in time efficiency(53.88% and 26.66% comapred with BERS and BERS+ respectively) and also minimizes energy consumption.

  • A Study on Packet Scheduling Algorithms for Healthcare Contents over Fifth
           Generation (5G) Mobile Cellular Network

    • Authors: Huda Adibah Mohd Ramli
      Pages: 729 - 735
      Abstract: This paper models the downlink Fifth Generation (5G) network that supports a flexible frame structure and a shorter Round Trip Time (RTT) for Hybrid Automatic Repeat Request (HARQ).  Moreover, the design of the renowned Time Division Multiple Access (TDMA) packet scheduling algorithms is revised to allow these algorithms to support packet scheduling in the downlink 5G. Simulation results demonstrate that the Proportional Fair provides a comparable performance to the delay–aware Maximum-Largest Weighted Delay First for simultaneously providing satisfactory transmission reliability of the Guaranteed Bit Rate (GBR) and Non-Guaranteed Bit Rate (Non-GBR) healthcare contents whilst maximizing the downlink 5G performance.

  • Design of a Predictive PID Controller using Particle Swarm Optimization

    • Authors: Fazida Hashim, Norhaida Mustafa
      Pages: 737 - 743
      Abstract: The proportional-integral-derivative (PID) controller is widely used in various industrial applications such as process control, motor drives, magnetic and optical memory, automotive, flight control and instrumentation. PID tuning refers to the generation of PID parameters (Kp, Ki, Kd) to obtain the optimum fitness value for any system. The determination of the PID parameters is essential for any system that relies on it to function in a stable mode. This paper proposes a method in designing a predictive PID controller system using particle swarm optimization (PSO) algorithm for direct current (DC) motor application. Extensive numerical simulations have been done using the Mathwork’s Matlab simulation environment. In order to gain full benefits from the PSO algorithm, the PSO parameters such as inertia weight, iteration number, acceleration constant and particle number need to be carefully adjusted and determined. Therefore, the first investigation of this study is to present a comparative analysis between two important PSO parameters; inertia weight and number of iteration, to assist the predictive PID controller design. Simulation results show that inertia weight of 0.9 and iteration number 100 provide a good fitness achievement with low overshoot and fast rise and settling time. Next, a comparison between the performance of the DC motor with PID-PSO, with PID of gain 1, and without PID were also discussed. From the analysis, it can be concluded that by tuning the PID parameters using PSO method, the best gain in performance may be found. Finally, when comparing between the PID-PSO and its counterpart, the PI-PSO, the PID-PSO controller gives better performance in terms of robustness, low overshoot (0.005%), low minimum rise time (0.2806 seconds) and low settling time (0.4326 seconds).

  • Start acceleration of the space GPS receiver

    • Authors: Pavel Kovář
      Pages: 745 - 752
      Abstract: The cold start of the space GPS receiver, i.e. the
      start without any information about the receiver position, satellite
      constellation, and time, is complicated by a large Doppler shift
      of a navigation signal caused by the satellite movement on the
      Earth orbit. That increases about five times the search space of
      the navigation signals compared to the standard GPS receiver.
      The paper investigates a method of the acceleration of the GPS
      receiver cold start time designed for the pico- and femto-satellites.
      The proposed method is based on a combination of the parallel
      search in Doppler frequency and PRN codes and the serial search
      in code phase delay. It can shorten the cold start time of the GPS
      receiver operating on LEO orbit from about 300 to 60 seconds
      while keeping the simplicity of FPGA signal processor and low
      power consumption. The developed algorithm was successfully
      implemented and tested in the piNAV GPS receiver. The energy
      required for the obtaining of the position fix was reduced five
      times from 36 on to 7.7 Joules. This improvement enables
      applications of such receiver for the position determination in
      smaller satellites like Pocket Cube or femto-satellites with a lower
      energy budget than the Cube Satellite.

  • The behavioural model of graphene field-effect transistor

    • Authors: Maciej Łuszczek, Marek Turzyński, Dariusz Świsulski
      Pages: 753 - 758
      Abstract: The behavioural model of a graphene field-effect
      transistor (GFET) is proposed. In this approach the GFET
      element is treated as a “black box” with only external terminals
      available and without considering the physical phenomena
      directly. The presented circuit model was constructed to reflect
      steady-states characteristics taking also into account GFET
      capacitances. The authors’ model is defined by a relatively small
      number of equations which are not nested and all the parameters
      can be easily extracted. It was demonstrated that the proposed
      model allows to simulate the steady-state characteristics with the
      accuracy approximately as high as in the case of the physical
      model. The presented compact GFET model can be used for
      circuit or system-level simulations in the future.

  • Localization technique of IoT nodes using artificial neural networks (ANN)

    • Authors: Beata Krupanek, Ryszard Bogacz
      Pages: 769 - 774
      Abstract: One of the ways to improve calculations related to determining the position of a node in the Iot measurement system is to use artificial neural networks (ANN) to calculate coordinates. The method described in the article is based on the measurement of the RSSI (Received Signal Strenght Indicator), whitch value is then processed by the neural network. Hence, the proposed system works in two stages. In the first stage, RSSI coefficient samples are taken, and then the node location is determined on an ongoing basis. Coordinates anchor nodes (i.e. sensors with fixed and previously known positions) and the matrix of RSSI coefficients are used in the learning process of the neural network. Then the RSSI matrix determined for the system in which the nodes with unknown positions are located is fed into the neural network inputs. The result of the work is a system and algorithm that allows determining the location of the object without processing data separately in nodes with low computational performance.

  • The Carbon Footprint Methodology in CFOOD Project

    • Authors: Zofia Stawska, Piotr Milczarski, Bartosz Zieliński, Artur Hłobaż, Paweł Maślanka, Piotr Kosiński
      Pages: 781 - 786
      Abstract: In the paper, the research on the process of optimizing the carbon footprint to obtain the low-carbon products is presented. The optimization process and limits were analyzed based on the CFOOD project co-financed by the Polish Research and Development Agency. In the article, the carbon footprint (CF) testing methods with particular emphasis on product life cycle assessment (LCA) are discussed. The main problem is that the energy received from the energy-meters per the production stage is not directly represented in the raw data set obtained from the factory because many machines are connected to a single measurement point. In the paper, we show that in some energy-demanding production stages connected with cooling processes the energy used for the same stage and similar production can differ even 25-40%. That is why the energy optimization in the production can be very demanding.

  • Low cost design methods to enhance resolution and dimensions for printed
           electrodes

    • Authors: Grzegorz Tarapata, Michał Marzęcki
      Pages: 793 - 799
      Abstract: In the paper, we demonstrate the feasibility of fabrication interdigitated electrodes with the usage of inkjet printing technology. The emphasis was put to obtain better shape quality and lower spacing between electrodes with respect to the typical printing process. The paper presents an analysis of the main factors that have an influence on the dimension and quality of printed structures and proposes methods that allow eliminating the main problems. The first proposed method is based on controlling the time between patterning successive drops. While the second method is based on changing the design methods and printing orientation. Both methods do not require any additional technological processes or the use of any special surface preparation methods. Finally, the obtained results and conclusions were presented and discussed.
