    IOT-based and Auto Firmware System for Transmitting Notifications and Advertisements via GSM/GPRS ModemsIOT-based and Auto Firmware System for Transmitting Notifications and Advertisements via GSM/GPRS Modems
    (October university for modern sciences and Arts MSA, 2023) A. A. Mohamed, Mokhtar; M.R.Aboueid, Ahmed; Akl ElSayed, Tahany; El-Shafeiy, Engy
    Recently, it has been a kind of trend that many applications adopt IOT-based SMS services for delivering notifications and advertisements (i.e. ads) to their users. As a result, we are mobilized to design and develop a GSM-based system within this paper to send alerts and ads in our faculty community as SMS messages. This system is called "NATEGA" as an abbreviation of "Naïve and Auto firmware for Transmitting Exam Grades and Advertisement via SMS messages". The Hardware part of NATEGA system consists of three main modules; GSM/GPRS Module (GGM), USB-to-TTL bridge Module (UTM), and DC-to-DC Converter Module (DDC). Any PC or laptop can be employed for execution of the NATEGA program (i.e. software part) which is developed in C# programming language. The efforts, that have taken place intentionally during design of NATEGA system, led to support both Push paradigm and Pull paradigm concepts in sending notifications and ads. Four performance metrics are used to validate and verify the feasibility of NATEGA system. They are Message Construction Time (MCT), Message-to-Modem Delivering Time (MMDT), SMS Delivery Report Time (SDRT), and Success in Delivering SMS Ratio (SDSR). Time-based metrics (MCT, MMDT, and SDRT) are chosen for evaluation because the provision of timely information is imperative for applications of delivering notifications and ads

    USANet: an open platform for USB-based Sensors/Actuators Network
    (October university for modern sciences and Arts MSA, 2023) Mohamed, Mokhtar; El-Shafeiy, Engy; Gad, Ramadan; ElMahalawy, Ahmed
    The paper presents and proposes USB-based Sensors/Actuators Network (USANet) system. Proposed USANet system is maturely designed according to IEEE 1451 concepts and component-based approach. It consists of five STIMs. These STIMs are Measurement Module of Speed (MMS), Controller Module for Motor (CMM), three Measurement Modules of Distance (MMDs). They are connected to a laptop NCAP host via five USB 2.0 interface cards. Each USB 2.0 interface card is dedicated for only one STIM to exchange messages of sensory data or control commands with NCAP host. USB 2.0 interface card represents TII of such USANet. NCAP host run a program called SCCD. SCCD is the abbreviation of Sensory data Collector/Command Distributor. It is an open source model that is developed by C# programming language under the dot-Net 4.0 framework to provide portability. SCCD is employed to collect sensory data from MMS, and three MMDs. In addition, SCCD sends control commands to CMM. All hardware and software modules of USANet are designed and developed completely in our labs. Two performance metrics are used to validate and verify the feasibility of such USB-based Networked system. They are Feedback Receiving Time (FRT) and Sensory Data Message Time (SDMT). These timebased metrics are chosen for evaluation because the provision of timely information is crucial in many applications
