Communication models
Contenido
Desde un punto de vista operativo, tiene sentido pensar en cómo se conectan y comunican dispositivos del IdC desde la perspectiva del modelo de comunicación. En 2015, la Junta de Arquitectura de Internet (IAB) publicó un documento orientación para la creación de redes de objetos inteligentes (RFC 7452) que describe marcos de cuatro modelos de comunicación comunes utilizados en dispositivos de comunicación al Internet de las Cosas.
El modelo de comunicación dispositivo a dispositivo representa dos o más dispositivos que se conectan y se comunican directamente entre sí y no a través de un servidor de aplicaciones intermediario. Estos dispositivos se comunican sobre muchos tipos de redes, entre ellas las redes IP o la Internet. Sin embargo, para establecer comunicaciones directas de dispositivo a dispositivo, muchas veces se utilizan protocolos como Bluetooth.
En un modelo de comunicación de dispositivo a la nube, el dispositivo de la IoT se conecta directamente a un servicio en la nube, como por ejemplo un proveedor de servicios de aplicaciones para intercambiar datos y controlar el tráfico de mensajes. Este enfoque suele aprovechar los mecanismos de comunicación existentes (por ejemplo, las conexiones Wi-Fi o Ethernet cableadas tradicionales) para establecer una conexión entre el dispositivo y la red IP, que luego se conecta con el servicio en la nube.
En el modelo dispositivo a puerta de enlace, o más generalmente el modelo dispositivo a puerta de enlace de capa de aplicación (ALG), el dispositivo de la IoT se conecta a través de un servicio ALG como una forma de llegar a un servicio en la nube. Dicho de otra manera, esto significa que hay un software de aplicación corriendo en un dispositivo de puerta de enlace local, que actúa como intermediario entre el dispositivo y el servicio en la nube y provee seguridad y otras funcionalidades tales como traducción de protocolos o datos.
El modelo de intercambio de datos a través del back-end se refiere a una arquitectura de comunicación que permite que los usuarios exporten y analicen datos de objetos inteligentes de un servicio en la nube en combinación con datos
de otras fuentes. Esta arquitectura soporta “el deseo del usuario de permitir que terceros accedan a los datos subidos por sus sensores”.
Consumer applications
A growing percentage of IoT devices are built for consumption. Some examples of consumer applications include: connected cars, entertainment, home automation, wearable technology, connected health and home appliances such as washing machines, dryers, robotic vacuum cleaners, air purifiers, ovens, refrigerators that use Wi-Fi for remote monitoring of processes.[34].
Some consumer applications have been criticized for their lack of redundancy and inconsistency. These criticisms gave rise to a parody known as the Internet of Shit.[35] Several companies have been criticized for rushing into IoT, thus creating devices of questionable value,[36] as well as failing to establish and implement well-prepared security standards.[37].
Business
The term “Enterprise IoT” (EIoT) is used to refer to all devices in the business and corporate environment.
By 2019, it is estimated that EIdC" will comprise about 40% or 9.1 billion devices.[15].
Business: Energy and water industry
The Internet of Things (IoT) has significantly transformed the management of energy and water resources by enabling the interconnection of critical infrastructure through sensors, smart meters and cloud-based analytics platforms. These applications seek to optimize consumption, reduce losses and improve sustainability in strategic sectors.[38].
Energy.
In the energy sector, IoT is used in smart grids for real-time monitoring of demand and generation. Smart meters allow electricity companies to collect detailed information on users' consumption, facilitating energy efficiency policies, dynamic rates and the integration of renewable sources. Likewise, the use of sensors in generation plants and transmission lines improves early failure detection and preventive maintenance planning, reducing operating costs and risks of massive blackouts.
Water.
In water management, IoT systems contribute to pressure control in distribution networks, early detection of leaks and monitoring the quality of the resource. Water companies have implemented smart meter networks to monitor consumption patterns, identify anomalous uses and prevent unaccounted losses. In addition, environmental sensors located in basins and pumping stations make it possible to anticipate critical events such as droughts or floods, which is essential for water security and adaptation to climate change.[39].
Impact and benefits.
IoT adoption in energy and water not only increases operational efficiency and infrastructure resilience, but also enables data-driven sustainable management models. These advances contribute to the sustainable development goals related to affordable and clean energy (SDG 7) and clean water and sanitation (SDG 6).[40].
The media uses the Internet of Things mainly for marketing and studying consumer habits. These devices collect useful information about millions of individuals through behavioral segmentation.[41] By making use of the profiles built during the segmentation process, media producers present consumers with on-screen advertising aligned with their known habits at the right place and time to maximize their effect.[42][43] More information is collected by tracking how consumers interact with the content. This is done by measuring performance indicators such as abandonment rate, click-through rate, registration rate or interaction rate. The amount of information that is handled represents a challenge, since it begins to delve into the domains of big data. However, the benefits obtained from the information far outweigh the complications of its use.[44][45].
Infrastructure management
The monitoring and control of urban and rural infrastructure operations such as bridges, railways and wind farms is a key application of IoT.[46] IoT infrastructure can be used to track any events or changes in structural conditions that may compromise safety and increase risk. It can also be used to plan repair and maintenance activities efficiently, coordinating tasks between different service providers and facility users.[19] Another application of IoT devices is the control of critical infrastructure, such as bridges to allow the passage of vessels. The use of IoT devices for monitoring and operating infrastructure can improve incident management, coordination of response in emergency situations, quality and availability of services, in addition to reducing operating costs in all areas related to infrastructure.[47] Even areas such as waste management[48] can benefit from the automation and optimization that the application of IoT would bring[49].
Other fields of application
Agriculture.
The world population will reach 9.7 billion in 2050 according to the United Nations, therefore, to feed this large population the agricultural industry must adopt the IoT.
IoT-based smart farming will enable producers and farmers to reduce waste and improve productivity, from the amount of fertilizer used to the fuel used in agricultural machinery. In IoT based agriculture, a system is built to monitor the crop field with the help of sensors (light, humidity, temperature, soil moisture) and automation of the irrigation system.
Farmers can monitor field conditions from anywhere. IoT-based farming is highly efficient compared to traditional farming. In terms of environmental issues, IoT-based agriculture can provide great benefits, including more efficient use of water, or the optimization of inputs and treatments.
IoT devices can be used for remote patient tracking and emergency notification systems.
These devices can range from blood pressure monitors and heart rate monitoring, to devices capable of tracking specialized implants, such as pacemakers, electronic bracelets, or sophisticated hearing aids.[19] Some hospitals have begun using "smart beds" that detect when they are occupied and when a patient attempts to get up. It can also be automatically adjusted to ensure that the patient has adequate support without interaction from nursing staff.[50].
Specialized sensors can be installed in living spaces to monitor the health and general state of well-being of older people.[51] Other consumer IoT devices encourage healthy living, for example, connected scales or wearable heart monitors.[52] More and more comprehensive IoT tracking platforms are emerging for prenatal and chronic patients that help track vital signs and necessary medication administration. The US plans to save up to USD 300 billion from the national budget due to medical innovations.[53].
DEKA Research and Development Corporation (DEKA (company)), a company that creates prosthetic limbs, has created a battery-powered arm that transforms the electrical activity of skeletal muscles to control it. The arm was named Luke Arm (Luke's arm, in English) in honor of Luke Skywalker (Star Wars).[54].
In the transportation sector, the Internet of Things is called the Internet of Vehicles. IoT can assist the integration of communications, control and information processing across various transportation systems, offering solutions to the multiple challenges that arise throughout the logistics chain.[55].
The application of IoT extends to all aspects of transportation systems (vehicles, infrastructure, drivers or users). The dynamic interaction between these components of a transportation system allows inter- and intra-vehicular communication, intelligent traffic control, smart parking, electronic toll collection, logistics and fleet management, vehicle control, security and route assistance.[19][56] In logistics and fleet management, for example, the IoT platform can track the location and conditions of cargo and assets at all times through wireless sensors that send alerts in case of eventualities (delays, damage, theft, etc.).
