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

Abstract

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
