    Assessment of Quality of Service of G.S.M. Networks in Ilorin Metropolis, Nigeria
    (Ahmadu Bello University, Kaduna Nigeria, 2020-06-30) SURAJUDEEN-BAKINDE, Nazmat Toyin; Adeniji, Kehinde Adetunji; Oyeleye, Sam Oloruntoba; Zakariyya, Sikiru Olayinka; Olayanju, Sunday Akinwale; Usman, Ayinde Mohammed
    Following the rollout of GSM services across Nigeria, the socio-economic landscape of the country has been positively altered. Its explosive growth has brought huge revenues to the operators, as well as the government and at the same time benefited the citizens in many ways. However, the principal developmental factors that has continued to mar these benefits is the aggressive complaints from GSM subscribers regarding the horrible Quality of Service (QoS) rendered by the GSM operators across the country. As the number of subscribers of GSM in Nigeria increased, congestion rates also increased and there has been a huge demand for a decent QoS in the country. In this study, three key performance indicators (KPI) parameters, call setup success rate (CSSR), received signal level (RSL) and call drop rate (CDR) were used in assessing the performance of two of the major GSM networks in Ilorin Metropolis of Nigeria, which have been tagged Network “A” and Network “B”. A and B monitored are far from providing reliable services to Nigerians. None of the networks in the study met the ≥ 98% CSSR required by the N.C.C. regulations, and none met the ≤ 2% CDR required by the N.C.C. regulations. The problems GSM operation encountered have been attributed to a number of challenges, with cited faults ranging from the Network providers, to regulatory agencies, and even to the Nigerian Government.

    Design and Implementation of a Cloud-Based Load Monitoring Scheme for Electricity Theft Detection on a Conventional Grid
    (Jordan Journal of Electrical Engineering, 2022-12) Abdullateef, A. I; Sulaiman, A; Issa, A. O; Zakariyya, Sikiru Olayinka
    Electricity theft is one of the problems - encountered by the utilities - that leads to losses of revenue. Manual monitoring of the consumers’ activities which shows the energy data consumed on the conventional grid has largely contributed to electricity theft on the grid. Significantly, the energy meter deployed to monitor the load cannot store and transmit energy data in real-time. This has made electricity theft on the grid unnoticed. This paper presents the development of a monitoring scheme for an electronic meter on the conventional grid with the capability to monitor, store and transmit consumers’ energy data to the cloud. It consists of two units: the indoor and the outdoor unit. Energy data is transferred wirelessly between the units via the Wi-Fi modules. The outdoor unit compares the data and transfers the outcome to the ThinkSpeak cloud server. The transferred energy data can be accessed in real-time from the cloud or downloaded in comma-separated values format for further use. In order to verify the functionality of the proposed scheme, two scenarios of electricity theft - partial bypassing and full bypassing - are carried out. The obtained results show that the scheme can detect the theft and log the data to the cloud successfully

    Design of a Low-Cost Controller for Smart Prepaid Meters
    (Department of Electrical Engineering, Ahmadu Bello University, Zaria, Nigeria., 2020-09-25) Zakariyya, Sikiru Olayinka; Abara, I E; Olayanju, Sunday Akinwale; Salami, A F; Sadiq, B O; Alao, R A
    This paper presents the design and implementation of a low-cost, low-complexity, energy-efficient controller with remote recharge and load shedding capability. The system is recharged remotely by an SMS sent to a registered SIM card in a GSM module, a voltage and current sensor measures the load power usage, a microcontroller is used to keep track of the power consumption and signals the relay in order to execute the load shedding when the predetermined threshold is reached. The whole system is powered by a power supply unit which converts the 220V AC from the supply mains to a 5V DC. After the design and upon testing, the energy measurement circuit worked with minimal error, the relay switch executed the load shedding function without delay, the GSM showed good network reception and the operation of the system was cheap and simple thus satisfying the objective of the research

    Development of Face Recognition-Based Attendance System
    (Faculty of Natural and Applied Sciences (FNAS) and the Faculty of Computing and Information Technology (FCIT), Sule Lamido University, Kafin Hausa, Jigawa State, Nigeria, 2023-05) Chukwude, Okechukwu M; SURAJUDEEN-BAKINDE, Nazmat Toyin; Zakariyya, Sikiru Olayinka; Ogunsakin, Joy B; Akanni, Jimoh; Olayanju, Sunday Akinwale; Ehiagwina, Frederick O
    Lecture attendance management is usually tedious, and time-consuming and may be prone to errors or manipulations when done manually. Hence, in this work, a web application called RollCall was developed and tested, for use by both students and lecturers in the Faculty of Engineering at the University of Ilorin as a model to manage attendance. The system manages attendance by allowing the lecturers to create courses, and take and retrieve attendance records for the courses created. Student functionalities include uploading their face data, enrolling for courses, and retrieving attendance records for the courses in which they enrolled. Attendance is marked through face recognition technology implemented with Python, OpenCV and Sci-kit Learn. The web interface was implemented using HTML5, Twitter Bootstrap CSS framework and JavaScript. The findings revealed that RollCall effectively streamlined attendance management, making it easier for both students and lecturers to keep track of attendance records. The web application is user-friendly and enhances the overall academic experience by improving the accuracy and efficiency of attendance management.

    Prediction of Run-off Time for Water Film Thickness and the Effects on Wet Antenna Attenuation
    (FUOYE Journal of Engineering and Technology (FUOYEJET), 2023-03) Abdulrahman, Amuda Yusuf; Salaudeen, Kazeem; Zakariyya, Sikiru Olayinka; Akanni, Jimoh; Afolabi, A. S; Ajiboye, A . T
    Most of the reported works on wet antenna attenuation (WAA) focused on the estimation of the water-layer thickness without considering the time taken to be drained off from the reflector (that is, the runoff time). Simulated rain experiments were conducted on a parabolic antenna with a diameter of 0.6 m. Based on measurement data, this study examined the parametric effects of rain rate on water film thickness and runoff duration, and then associated those findings to the overall WAA. It was found that WAA increases with the water film thickness, while decreasing with the runoff time. More so, the latter quantity both increase with the antenna dish size. The study is useful in accounting for the WAA component in the overall link budget design for adequate service delivery.

    A Survey on Medium Access Control Protocol for Wireless Body Area Nanosensor Network
    (Algorithms for Intelligent Systems. Springer, 2022) Zakariyya, Sikiru Olayinka; Usman, A. D.; Tekanyi, A. M. S.; Yaro, A. D.
    The body area nanosensor network represents a new paradigm shift that extends beyond the traditional sensor and body area network. It is envisioned that the implanted nanodevices will take measurements from inside the body and send the measured data to the outside world thereby reducing the rate at which patients constantly visit the hospital. However, this network is limited with energy-constrained and terahertz path loss which requires novel solutions. Medium access control is responsible for the management of the radio transmitter and receiver which is the highest energy-consuming part of the nanonodes. This research gives a thorough examination of medium access control (MAC) protocols designed for wireless body area nanosensor networks (WBANNs). We explore the design requirements for WBANNs with significant energy dissipation sources. Then, we look at the already developed protocols for WBANNs, focusing on their merits and drawbacks. The paper concludes with closing remarks and open research questions for further study.
