The Internet of Things - IoT is the extension of the Internet to the physical world in which it becomes possible to interact with objects and autonomous communication between them. Briefly, in the most conventional Internet different information is stored on computers around the world. This is a completely virtual world where they browse or interact with pages accessed through hyperlinks. In IoT, objects are identified and this identification can be read by automated means. From there, the physical objects now have a representation in the virtual environment. The fundamental concepts associated with IoT are:
- AIDC (Automatic Identification and Data Capture);
- Perception of context;
- Internet access.
A detailed exploration of the concepts presented above allows develop a complete model of the necessary development and deployment of applications and services IoT technologies. In this sense, there is a great interest due to the potential that this concept can be applied in building new business models applied to our market. A technological revolution that represents the future of computing and communication, whose development depends on the technical innovation of wireless sensors and nanotechnology is carrying. Advances related to miniaturization and nanotechnology mean that small objects would have the ability to interact and connect. Our country awake increasingly to issues related to the evolution of science and technology with emphasis to initiatives in the field of nanotechnology.
The benefits of this integrated information between industrial products and objects of daily use are possible from sensors that detect physical changes around them. These changes transform static objects into dynamic, combining intelligence in half and stimulating the creation of innovative new services and products. RFID technology presents itself as one of the most promising in this regard. The greater interaction and interface with the physical world resulting from the development and use of the Internet of Things raises questions about the social, safety and economic factors with emphasis on issues related to privacy and security of the information contained in the objects connected by RFID , smart cards , mobile phones (smartphones) , tablets , etc. The combination of these developments will create an Internet of Things links the objects in the world of intelligent sensory mode.
The main challenges that we observe are related to infrastructure , security, applications and services , particularly in relation to autonomous communications systems , where resources are inadequate the current internet.
However, considering only the technological dimension is insufficient to comprehend the universe IoT realistic roadmaps and build it properly to target investment and R & D efforts for the society to enjoy as soon as possible benefits from the IoT.
Some of these aspects may present real challenges such as:
- Applications and services;
- Networks and Infrastructure;
- Governance;
- Human behavior and interfaces;
- Usability;
- Restrictive standards;
- Security (safety and security);
- Business models;
- Platforms and Open Standards;
- Sustainability (ecological or financial);
- Environment or ecosystem.
In the Brazilian market, these systems are being used in several projects, particularly through the application of RFID technology. The main market segments that are using RFID technology in Brazil, with their respective foci of solutions are:
