    • Authors: anass deroussi, Abdessalam Ait Madi, Imam Alihamidi, Lalla Amina Charaf, Mohammed SABER, anass Erraoui, Adnane Addaim
      First page: 1
      Abstract: The internet of Things (IoT) irrigation systems are challenged by several issues, such as energy consumption and data storage. This paper proposes a novel energy-efficient, cost-effective IoT system called “NewAgriCom” to monitor agricultural field water flow. NewAgriCom is an autonomous remote SCADA based on a GPRS cellular network that effectively communicates irrigation field data to the node.js server. In JSON format, data is transmitted over the HTTP protocol to the MYSQL Database. Then data is transferred to the proposed IoT platform, which gives us a hand to control actuators, visualize, store and download the data.NewAgriCom can significantly reduce water consumption. It can be programmed to work automatically at specific times in various modes, including normal, light, and deep sleep modes; set a schedule to control water and provide the location, time, and signal strength with the Identifier of every device remotely.

  • COVID-19 Paediatric Cavity Telecare System: A Novel Chain Key (NCK)
           Generation and Encryption Scheme

    • Authors: JOYDEEP DEY
      First page: 13
      Abstract: In this unprecepented coronavirus crisis, teleheath has emerges as a substitute way of treatments. More specifically, paediatric children are at high risk to outside exposure now. Non critical children must be trated remotely through telecare system. A key based secured online transmission of intraoral image of paediatric cavity has been proposed in this manuscript. Cavity is a dental disease occurring in children. It is mainly caused due to prolonged bacterial infections. Secured online transmission with respect to online communication is required in Telecare Information System. Data confidentiality factor is preserved with preference in this proposed technique. A parity based Novel Chain Key (NCK) has been generated and diffused inside the intraoral paediatric cavity image. Novel Chain Key (NCK) generation scheme is so highly robust that it gives different combination after each bit altering. Initial seeds are kept at the dentist and patients, to resist myriad attacks inside the wireless channel, especially during this COVID-19 period.  Histogram, floating frequency, and autocorrelation were obtained with accuracy using the proposed technique. Effects were observed by flipping simultaneous bits of the initial key and results were highly acceptable.

    • Authors: Mochammad Haldi Widianto, Arief Ramadhan, Agung Trisetyarso, Edi Abdurachman
      First page: 25
      Abstract: The development of devices connected to the internet is very significant, encouraging the creation of the Internet of Things (IoT). With a remote system, IoT is not used enough because of the instability of the internet in several places like open areas or rural. By using LoRa, IoT systems can now communicate remotely if the internet is unstable. Millions of data make IoT- LoRa must use a lot of energy. This paper helps find where recent studies offer broad perspectives on energy savings using Systematic Literature Review (SLR). The paper extracted 252 articles from IEEE, ACM, MDPI, Springer, Hindawi, and IAES. 47 articles passed the specified inclusion and exclusion criteria. Based on the remaining articles, demography and factors energy savings. The author synthesizes studies for that purpose on IoT applications using LoRa.

  • Fuzzy-based MPPT algorithm implementation on FPGA chip for multi-channel
           photovoltaic system

    • Authors: hanen abbes
      First page: 49
      Abstract: Microprocessors and microcontrollers are mostly used to control electrical systems. These chips front into problems while monitoring systems that need heavy computing and important processing. Likewise, they fail while handling  inputs and outputs speeds, especially with multi-channel photovoltaic (PV) systems. In comparison to DSP ( : Digital Signal Processor) and microcontroller implementations, FPGA ( : Field Programmable Gate Array) device is able to integrate a great number of PV channels and to achieve short development time, cost less and more flexible operation. As well, new control algorithms are increasingly complex; using new performing technologies is very motivating. Mainly, FPGA technology is adopted thanks to its ability to control complex applications and intelligent laws. In opposition to traditional controls, fuzzy logic based control presents more efficiency and reliability response for non-linear systems.Therefore, this paper deals with the execution of fuzzy-based MPPT technique by the means of the FPGA chip for multi-channel photovoltaic system. Multi-channel photovoltaic system is designed. Then, FPGA circuit is investigated to get benefits from this hardware solution. Since software implementation way integrates a limited number of PV panels, hardware implementation is a promising solution that reduces execution time and therefore controls a huge number of photovoltaic channels. Finally, results of simulation of the fuzzy technique implementation on FPGA chip show that the proposed PV system controls more than 4400 channels. Therefore, system output power is increased and the system profitability is improved.

  • Towards More Accurate IRIS Recognition System by using Hybrid Approach for
           Feature Extraction Along with Classifier

    • Authors: ARIF ullah
      First page: 59
      Abstract: Iris recognition has emerged as one of the most accurate and reliable biometric approaches for the human recognition This paper present an accurate framework for iris recognition system using hybrid algorithm in preprocess and feature extraction section. The proposed model for iris recognition with significant feature extraction was divided into three main levels. First level is having pre-processing steps which are necessary for the desired tasks. Our model deploys on three types of datasets such as UBIRIS, CASIA and MMU and gets optimal results for performing activity. At last perform matching process with decision based classifier for iris recognition with acceptance or rejection rates. Experimental based results provide for analysis according to the false acceptance rate and false rejection rate. In third level, error rate will be check along some statistical measures for final optimal results. Based on the result the proposed approach provided most efficient result as compare the rest of the approach.

  • Distinct ρ-based Model of Silicon N-channel Double Gate MOSFET

    • Authors: Hameed Pasha Mohammad, H. C. Hadimani, Srinivasa Rao Udara
      First page: 71
      Abstract: Growing endless demand for digital processing technology, to perform high speed computations with low power utilization and minimum propagation delay, the metal-oxide-semiconductor (MOS) technology is facing these challenges by linear scaling the transistors with different channel modelling in present day microelectronic regime. Linear scaling of metal-oxide-semiconductor field-effect-transistors (MOSFET) is limited through Short Channel Effects (SCEs). Silicon N-channel Double gate MOSFETs (DG MOSFETs) features Short channel transistor with high forward transfer admittance to input capacitance ratio. In this research paper, a Distinct ρ-based Model is designed to simulate SCEs. Analytical Model for Channel Length and Simulated Model for Total internal device capacitance through  Distinct ρ-based Model are presented. The proposed Distinct ρ-based Model is suitable for Silicon Nanowire transistors and the effectiveness of the proposed model is validated through comparative results.

  • Customization of GPRS, and Wi-Fi Device Drivers for PXA270 of Linux OS
           Based Barcode Scanner

    • Authors: Sanket S Naik Dessai
      First page: 84
      Abstract: To access any device, it is necessary to have an access point. to A device driver is an entry point to access a device. This project is aimed to customize the wi-fi and GPRS device drivers in Linux OS for PXA270 (Intel Xscale Arm Processor). Customizing a device driver is a special way of designing software that can be more easily ported from one architecture to another without rewriting it from scratch The paper is discussing about the customisation of Wi-Fi and GPRS device driver in Linux OS for PXA270 (Intel Xscale ARM Processor). To develop a device driver, it is necessary to understand the processor architecture and Linux kernel internals and other design constraints. Since dynamically loaded driver module is attached to the existing kernel, and any error in the driver will crash the entire system. Resource allocation and implementation for a device is one of the main concerns for device driver developers. The device resources are input/output, memory, IRQs and ports. The required toolchain to build the cross-complier for the Intel Xscale ARM Processor was built on Linux platform. The customised device drivers of Wi-Fi, and GPRS was customised, and the customised images are made to port for PXA270 processor architecture on EMX-270 board. With all the supporting parameters the kernel images with drivers are build and ported efficiently. Also, a successful verification and testing had been performed for their functionalities.

  • An efficient multi-level cache system for geometrically interconnected
           many-core chip multiprocessor

    • Authors: Tirumale Ramesh, Khalid H Abed
      Pages: 93 - 102
      Abstract: Many-core chip multiprocessor offers high parallel processing power for big data analytics; however, they require efficient multi-level cache and interconnection to achieve high system throughput. Using on-chip first level L1 and second level L2 per core fast private caches is expensive for large number of cores. In this paper, for moderate number of cores from 16 to 64, we present a cost and performance efficient multi-level cache system with per core L1 and last level shared bus cache on each bus line of a cost-efficient geometrically bus-based interconnection. In our approach, we extracted cache hit and miss concurrencies and applied concurrent average memory access time to more accurately determine the cache system performance. We conducted least recently used cache policy-based simulation for cache system with L1, with L1/L2, and with L1/shared bus cache. Our simulation results show that an average system throughput improvement of 2.5x can be achieved by using system with L1/shared bus cache system compared to using only first level L1 or L1/L2. Further, we show that the throughput degradation for the proposed cache system is only within 5% for a single bus fault, suggesting a good bus fault tolerance.
