The network is the main part of the IoT. It is responsible for providing a practical and smart system that makes strong infrastructure. The network offers scalability to help devices coordinate with other lines with the Internet.

Sensors may be used in devices that are not net-connected, while devices need to be connected to the Net with IoT. Yet, sensing is a part of IoT, even if the device is not connected to the Net.

Like any other technology there are challenges which make the viability of IoT doubtful.

Security is one of the major concerns of experts who believe virtually endless connected devices and information sharing can severely compromise one?s security and well being. Unlike other hacking episodes which compromise online data and privacy with IoT devices can open gateway for an entire network to be hacked.

One such flaw is well presented by Andy Greenberg on wired.com where he works with hackers to remotely kill his Jeep on the highway. Another very relevant example is provided by W. David Stephenson in his post Amazon Echo: is it the smart home Trojan Horse? You can estimate the amount of personal and private data the connected devices will be producing once they are on a network. The major challenge for IoT tech companies is to figure out how the communication in the internet of things realm can be made truly secure.

The answer depends on the nature of the object, and it can be simple or complex. For example, a smart thermometer might have only one sensor, used to communicate ambient temperature to a remote weather-monitoring center. A wireless medical device might, in contrast, use various sensors to communicate a person?s body temperature, pulse, blood pressure, and other variables to a medical service provider via a computer or mobile phone.

Smart objects can also be involved in command networks. For example, industrial control systems can adjust manufacturing processes based on input from both other IoT objects and human operators. Network connectivity can permit such operations to be performed in “real time” ? that is, almost instantaneously.

Smart objects can form systems that communicate information and commands among themselves, usually in concert with computers they connect to. This kind of communication enables the use of smart systems in homes, vehicles, factories, and even entire cities.

Smart systems allow for automated and remote control of many processes. A smart home can permit remote control of lighting, security, HVAC (heating, ventilating, and air conditioning), and appliances. In a smart city, an intelligent transportation system (ITS) may permit vehicles to communicate with other vehicles and roadways to determine the fastest route to a destination, avoiding traffic jams, and traffic signals can be adjusted based on congestion information received from cameras and other sensors.

Buildings might automatically adjust electric usage, based on information sent from remote thermometers and other sensors. An Industrial Internet application can permit companies to monitor production systems and adjust processes, remotely control and synchronize machinery operations, track inventory and supply chains, and perform other tasks.

IoT connections and communications can be created across a broad range of objects and networks and can transform previously independent processes into integrated systems. These integrated systems can potentially have substantial effects on homes and communities, factories and cities, and every sector of the economy, both domestically and globally.

General Electric coined the term Industrial Internet in late 2012. It is effectively synonymous with the Industrial Internet of Things, and abbreviated as Industrial IoT or IIoT.

Many other companies and organizations are realizing the potential and significance of the Industrial IoT. A recent study conducted by Appinions and published in Forbes listed RTI as the #1 most influential company for the Industrial Internet of Things. Other influencers included Google, Cisco, GE, Omron, DataLogic and Emerson Electric.

The Industrial Internet Consortium also advocates for the advancement of the Industrial IoT. It is a not-for-profit organization that manages and advances the growth of the Industrial IoT through the collaborative efforts of its member companies, industries, academic institutions and governments. Founding members include AT&T, Cisco Systems Inc., General Electric, IBM and Intel.

The Internet of Everything is the intelligent connection of people, process, data and things.

The “Thing” commonly referred to by the concept of the Internet of Things is any item that can contain an embedded, connected computing device. A “Thing” in the IoT could be a shipping container with an RFID tag or a consumer’s watch with a WiFi chip that sends fitness data or short messages to a server somewhere on the Internet.

Businesses focus on getting products to the marketplace faster, adapting to regulatory requirements, increasing efficiency, and most importantly, persisting to innovate. With a highly mobile workforce, evolving customer, and changing supply chain demand, the IoT can move your enterprise forward, starting today.

Cyberattacks may also compromise privacy, resulting in access to and exfiltration of identifying or other sensitive information about an individual. For example, an intrusion into a wearable device might permit exfiltration of information about the location, activities, or even the health of the wearer.

In addition to the question of whether security measures are adequate to prevent such intrusions, privacy concerns also include questions about the ownership, processing, and use of such data. With an increasing number of IoT objects being deployed, large amounts of information about individuals and organizations may be created and stored by both private entities and governments.

With respect to government data collection, the U.S. Supreme Court has been reticent about making broad pronouncements concerning society?s expectations of privacy under the Fourth Amendment of the Constitution while new technologies are in flux, as reflected in opinions over the last five years.

Congress may also update certain laws, such as the Electronic Communications Privacy Act of 1986, given the ways that privacy expectations of the public are evolving in response to IoT and other new technologies. IoT applications may also create challenges for interpretation of other laws relating to privacy, such as the Health Insurance Portability and Accountability Act and various state laws, as well as established practices such as those arising from norms such as the Fair Information Practice Principles.

Nokia originally introduced this protocol as Wibree in 2006. Also known as Bluetooth Smart this protocol provides the same range coverage with much reduced power consumption as the original Bluetooth. It has similar bandwidth with narrow spacing as used by ZigBee. Low power latency and lower complexity makes BLE more suitable to incorporate into low cost microcontrollers.

Low power latency and lower complexity makes BLE more suitable to incorporate into low cost microcontrollers.

As far as application is concerned BLE is in healthcare sector. As wearable health monitors are becoming prevalent the sensors of these devices can easily communicate with a smart phone or any medical instrument regularly using BLE protocol.
