Single-Board Computer, Edge Computing and Virtualization Technology
The widespread adoption of cloud computing has resulted in centralized datacenter structures; however, there is a requirement for smaller-scale distributed infrastructures to meet the demands for speed, responsiveness, and security for critical applications. Single-Board Computers (SBCs) present numerous advantages such as low power consumption, low cost, minimal heat emission, and high processing power, making them suitable for applications such as the Internet of Things (IoT), experimentation, and other advanced projects.

Sensor Network Environments
New technologies have driven the rise of what is being termed as the fourth industrial revolution. The introduction of this new revolution is amalgamating the cyber and physical worlds, bringing with it many benefits, such as the advent of industry 4.0, the internet of things, cloud technologies and smart homes and cities. These new and exciting areas are poised to have significant advantages for society; they can increase the efficiency of many systems and increase the quality of life of people. However, these emerging technologies can potentially have downsides, if used incorrectly or maliciously by bad entities. The rise of the widespread use of sensor networks to allow the mentioned systems to function has brought with it many security vulnerabilities that conventional “hard security” measures cannot mitigate. It is for this reason that a new “soft security” approach is being taken in conjunction with the conventional security means. Trust models offer an efficient way of mitigating the threats posed by malicious entities in networks that conventional security methods may not be able to combat.

Cyber-Physical Systems with Process-Oriented Paradigm
Process Oriented Programming (POP) is a programming paradigm based on the concept of "processes" that determine the response (outputs) of a reactive system based on events (states of internal and external variables, timeouts). A process-oriented program is a set of interacting processes that can change their behavior (reaction to events), start and stop other processes, and be executed in parallel. The languages created within the framework of POP (e.g. Reflex, IndustrialC, poST) fit very well for specification various control algorithms, which can consist of hundreds and thousands of processes. In addition to the fact that process-oriented programs structurally and conceptually correspond to the technological description of the plant under control, they also have the following remarkable property. In process-oriented algorithms, the use of data is usually local, limited to one or more processes.

Dynamic Distributed Intelligence Architecture for Human Activity Recognition
A wide range of applications, including sports and healthcare, use human activity recognition (HAR). The Internet of Things (IoT), using cloud systems, offers enormous resources but produces high delays and huge amounts of traffic. Researchers propose a distributed intelligence and dynamic HAR architecture using smart IoT devices, edge devices, and cloud computing. These systems were used to train models, store results, and process real-time predictions. Wearable sensors and smartphones were deployed on the human body to detect activities from three positions; accelerometer and gyroscope parameters were utilized to recognize activities. A dynamic selection of models was used, depending on the availability of the data and the mobility of the users.

An Automation System for Controlling Streetlights
We present an Arduino-based automation system to control the streetlights based on solar rays and object’s detection. We aim to design various systems to achieve the desired operations, which no longer require time-consuming manual switching of the streetlights. The proposed work is accomplished by using an Arduino microcontroller, a light dependent resistor (LDR) and infrared-sensors while, two main contributions are presented in this work. Firstly, we show that the streetlights can be controlled based on the night and object’s detection. In which the streetlights automatically turn to DIM state at night-time and turn to HIGH state on object’s detection, while during day-time the streetlights will remain OFF. Secondly, the proposed automated system is further extended to skip the DIM condition at night time, and streetlights turn ON based on the objects’ detection only. In addition, an automatic door system is introduced to improve the safety measurements, and most importantly, a counter is set that will count the number of objects passed through the road. The proposed systems are designed at lab-scale prototype to experimentally validate the efficiency, reliability, and low-cost of the systems. We remark that the proposed systems can be easily tested and implemented under real conditions at large-scale in the near future, that will be useful in the future applications for automation systems and smart homes.

Far and Near Field Communication
In an RFID system, for communication to exist between a reader and a tag, energy and information must be transferred between them. There are two ways to transfer energy and information in passive tags. The first mode is Near Field, which involves coupling the tag inductively to an approximately circular magnetic field around the reader. And the second mode is Far Field, which uses a reflection technique called backscatter.

Obstacle Detection and Mapping in Vehicle-to-Vehicle Networks
Vehicle-to-Vehicle (V2V) networks, specifically Vehicular Ad Hoc Networks (VANETs), are central to enhancing road safety by improving vehicle visibility, particularly when traditional onboard sensors fall short. The crucial role that VANETs play in modern transportation systems is increasingly being recognized, with the ability to facilitate real-time communication between vehicles, improving situational awareness, and thereby enhancing road safety. However, the accuracy, integrity and security of these data are of paramount importance, as any inaccuracies or compromises could lead to incorrect hazard perception and possibly catastrophic consequences. Hence, substantial effort is required to maintain these data characteristics while enabling efficient and rapid data exchange.
