Internet of Things tutorials for computer science and engineering students for university exams preparation
Reference IoT Layered Architecture (RILA) consists of 6 layers. In addition, to there are two “cross-section layers that affect all other layers, namely “Security” and “Management”. Device Integration Layer The device integration layer connects all the different device types and consumes device measurements as well as it communicates actions. This layer can also work as a translator…
The Internet of Things (IoT) provides new opportunities for different IoT platforms to connect various devices together. The need to identify those devices is of foremost importance to performing any kind of operation. Many organizations and standard bodies that provide specifications and frameworks for the IoT currently have their own identification mechanisms. Some existing industrial identification mechanisms…
TinyOS was introduced by Jason Hill at the University of Berkeley in 2000. TinyOS is an open-source, BSD-based operating system that uses the nesC programming language to control and manage wireless sensor networks (WSN). The sensor devices (called motes) in such networks are characterized by low power, limited memory, and a very small form factor. The…
RIOT OS is free and open-source, It is specially designed to meet the particular needs of the IoT, with features like a low memory footprint, high energy efficiency, real-time capabilities, a modular and configurable communication stack, and support for a wide range of low-power devices. It is friendly to IoT applications. It is developed in 2008…
Arduino is a small and inexpensive electronic board that allows you to connect to various external accessories (such as sensors) and create applications to use the data collected. Another open-source hardware platform is Raspberry Pi. Raspberry Pi is a low-cost, credit card-sized computer that connects to a computer monitor or TV using HDMI and uses a standard…
LiteOS is an open-source, interactive, UNIX-like operating system designed for wireless sensor networks. With the tools that come with LiteOS, we can operate one or more wireless sensor networks in a Unix-like manner, transferring data, installing programs, retrieving results, or configuring sensors. LiteOS is written in C and runs on the Atmel AVR-based MicaZ and…
Contiki is an operating system like Microsoft, Windows, and LINUX for IoT that specifically targets small IoT devices with limited memory, power, bandwidth, and processing power. It provides functionality for the management of programs, processes, resources, memory, and communication. Many academics, organization researchers, and professionals consider it a go-to OS. Contiki only requires a few…
Arduino is like the brain of the system and processes the data from the sensor. Arduino is an open-source hardware platform that is readily available for hobbyists and enthusiasts across the globe to build projects. It is embedded with an ATMEGA microcontroller that processes the data and facilitates the proper working of the IoT system….
An actuator is a device, which can affect a change in the environment by converting electrical energy into some form of useful energy. Some examples are heating or cooling elements speakers, lights, displays, and motors. The actuators can be classified into three categories. electrical, hydraulic, and pneumatic actuators depending on their operation. Hydraulic actuators simplify…
IoT is composed of several technology layers which enable things to share the data they collect over the Internet to ultimately deliver intelligence, autonomous actions, and value which largely depend on the quality of the data itself. Therefore, sensors and actuators are an essential part of the IoT tech stack. A sensor, also called a…
