Description: Embedded networks refer to the integration of networking capabilities into embedded systems, which are devices designed to perform specific functions within a larger system. These systems often have limited resources in terms of processing, memory, and energy, making them ideal for applications where efficiency is crucial. The incorporation of networking capabilities allows these devices to communicate with each other and with other systems, facilitating real-time data collection and exchange. Embedded networks are fundamental in the context of the Internet of Things (IoT), where a variety of devices, from household appliances to industrial sensors, are interconnected. This not only enhances the functionality of devices but also enables automation and remote control, resulting in greater operational efficiency and improved user experience. Key features of embedded networks include the ability to operate in resource-constrained environments, the implementation of specific communication protocols, and the capability to perform remote software updates. In summary, embedded networks are an essential part of modern technology, enabling interconnection and communication between devices across various applications.
History: Embedded networks began to take shape in the 1990s with the rise of microcontroller technology and the expansion of the Internet. As devices became smaller and more powerful, the need to connect them to networks to enhance their functionality emerged. In 1999, the term ‘Internet of Things’ was coined by Kevin Ashton, marking a milestone in the evolution of embedded networks, as a vision of a world where everyday objects could communicate with each other began to take form. Since then, technology has rapidly advanced, with the emergence of protocols like MQTT and CoAP, specifically designed for resource-constrained environments.
Uses: Embedded networks are used in a wide variety of applications, including home automation, where devices like smart thermostats and security cameras communicate with each other and with users. They are also common in various industries, where sensors and actuators are integrated into control systems to monitor and optimize processes. In healthcare, connected medical devices enable remote patient monitoring, improving healthcare delivery. Additionally, embedded networks are essential in smart city management, where they are used to control traffic, lighting, and other public services.
Examples: Examples of embedded networks include devices like the Nest thermostat, which allows users to remotely control their home’s temperature, and health monitoring systems like glucose tracking devices that send data to doctors. In the industrial sector, temperature and humidity sensors in factories that communicate with centralized management systems are another clear example of embedded networks in action.
