about internet of things

1. What is Internet O f T hings? IOT systems allow user to achieve deeper automation, analysis, integration with in a system. They improve the reach of these areas and accuracy. This system allows greater transparency, control, and performance when applied to any industry or system . Enhance data collection , automation, operations, and much more through their smart devices and powerful enabling technology . " Distributed Systems and Internet of Things" represents a vision in which the Internet extends into the real world embracing everyday objects. Physical items are no longer disconnected from the virtual world, but can be remotely controlled and can act as physical access points to Internet services.

2. contd … The back end of these physical access points is a geographically distributed system which integrates such diverse technologies as pervasive, mobile and Cloud computing. IoT relies on advanced connectivity of devices, systems, and services that covers a variety of protocols, domains, and applications. It is expected to usher in automation in nearly all fields, while also enabling advanced applications like Smart environments. Decentralized system of cooperating smart objects (SOs) are emerging as a new paradigm for IoT .

3. contd … Smart Objects are able to sense/actuate, store, and interpret information created within themselves and around the neighboring external world where they are situated, act on their own, cooperate with each other, and exchange information with other kinds of electronic devices and human users. The key innovation of the "Internet of Things" concept is that we're equipping distributed systems with senses that allow them (their programs) to acquire information in a self-motivated fashion, to make decisions, and to actuate things in the physical world as a result. Systems are the focus, not the things. The things are peripherals.

4. IOT applications The applications for IoT are enormous. In healthcare, a range of sensors attached to any number of patients can transmit data about that patient to a central management console, alerting doctors and nurses when certain conditions are detected. In the home, IoT applications are essentially already in use, where smart appliances like a refrigerator can signal the need for new water filters, and thermostats can both report temperature data and receive commands to adjust the temperature. And in agriculture, things like sensors on cows can report everything from the body temperature to signs of stress or disease.

5. contd … F or IoT applications, a client-server approach may not be the best model. For example, in many areas, the sensors may be required to make some decisions locally, or communicate with more than one external source based on the data collected. And once self-driving cars come online in a big way, any IoT -type devices onboard those cars will likely need to make some decisions instantly, without waiting to be told what to do by the centralized compute source. At the same time, a fully distributed model will also fail, as the cost and technical constraints that the sensors have will not allow heavy computing and storage resources to be integrated into the sensors.
