“…FreeRTOS was studied to enhance students' practical experiences in five key real-time concepts i.e. task management, queue management, interrupt management, resource management, and memory management [14]. However, the design used for users to interact with the microcontroller with FreeRTOS were not reported.…”

Distance learning has become a crucial alternativein education system worldwide since the Covid-19 pandemic happened. An affordable and accessible solution is essentialto enable a quality remote teaching and learning experience for each student. Real-Time Embedded System (RTES) is about applying real-time system in an embedded system (e.g., microcontroller) in ways that both logical and temporal requirements are fulfilled. A special attention shall be on the temporal response analysis so that students can have a clear distinction between microcontrollers with and without real-time system.Since there is a lack of accessible traceable studies about how to utilize the open-source platform inintroducing the key RTES concepts, this study aims to evaluate the feasibility of an integration of open-source resources (i.e., SimSo simulator, Arduino platform and FreeRTOSAPI) in teaching RTES remotely and to provide real-time learning experience about RTES concepts without additional components or wiring out of school. First, each student was introduced to the ways to integrate existing open-source resources so that each of them could develop RTES in their placesusing a FreeRTOS compatible microcontroller.RTES concepts of task, hyperperiod, task scheduling, pre-emption,static-priority scheduling algorithms, and mutual exclusion in resource sharing were delivered using the proposed infrastructure. Results show that an obvious context switch could be observed when pre-emption happened. Finding indicates that the proposed integration was useful for students to understand the complex RTES concepts e.g., task scheduling, pre-emption, and mutuallyexclusion.Since positive responses were received from students in two consecutive semesters, the proposed infrastructure is an affordable and accessible distance learning alternative in assisting students to understand RTES concepts.

Internet of Things (IoT) is an integration of the Sensor, Embedded, Computing, and Communication technologies. The purpose of the IoT is to provide seamless services to anything, anytime at any place. IoT technologies play a crucial role everywhere, which brings the fourth revolution of disruptive technologies after the internet and Information and Communication Technology (ICT). The Research & Development community has predicted that the impact of IoT will be more than the internet and ICT on society, which improves the wellbeing of society and industries. Addressing the predominant system-level design aspects like energy efficiency, robustness, scalability, interoperability, and security issues result in the use of a potential IoT system. This paper presents the current state of art of the functional pillars of IoT and its emerging applications to motivate academicians and researches to develop real-time, energy-efficient, scalable, reliable, and secure IoT applications. This paper summarizes the architecture of IoT, with the contemporary status of IoT architectures. Highlights of the IoT system-level issues to develop more advanced real-time IoT applications have been discussed. Millions of devices exchange information using different communication standards, and interoperability between them is a significant issue. This paper provides the current status of the communication standards and application layer protocols used in IoT with the detailed analysis. The computing paradigms like Cloud, Cloudlet, Fog, and Edge computing facilitate IoT with various services like data offloading, resource and device management, etc. In this paper, an exhaustive analysis of Edge Computing in IoT with different edge computing architectures and existing status are deliberated. The widespread adoption of IoT in society has resulted in privacy and security issues. This paper emphasizes on analyzing the security challenges, privacy and security threats, conventional mitigation techniques, and further scope for IoT security. The features like fewer memory footprints, scheduling, real-time task execution, fewer interrupt, and thread switching latency of Real-Time Operating Systems (RTOS) enables the development of time critical IoT applications. Also, this review offers the analysis of the RTOS's suitable for IoT with the current status and networking stack. Finally, open research issues in IoT system development are discussed.
