Ultimate Guide To Learning The Internet Of Things

The idea of having a house or objects work by themselves for their human owners is something that is commonly seen in science fiction literature or Hollywood movies. It’s an idea that has captured human interest for quite some time. After all, who wouldn’t want to wake up in the morning to find their kitchen appliances made some fantastic fresh orange juice? While it may have seemed like a distant reality in the past, it’s quite close to becoming a reality now. The technology backing it up is known as the Internet of Things (IoT).

What is the Internet of Things?

At times also called the Internet of Everything (IoE), the IoT is constituted by a web-enabled device that receives and transmits the information as a center of control. It can collect and send data on the environment, which it gathers through an embedded system of processors, sensors, and related hardware. Hence, different devices can communicate with one another, providing key information via the web device. It’s a network that involves Machine to Machine communication that makes the individual devices connected.

While the human owners can program the device and give it instructions, once it’s enabled, it functions on its own and does not require any human interference. Due to its ability to run by itself, the Internet of Things can have an entire system of small devices run along with one another. The devices, when operational, will generate a lot of data movement that will require a great amount of internet traffic to run. However, while the system is not small or light by any means, it generates several useful functions.

Internet of Things (IoT): A History

The idea of IoT has existed for quite some time, with mentions to it dating back to 1999. While the references made then did not use the term “Internet of Things”, they did provide the ideas that have come to be known in IoT now. Everything from the uses to the benefits had come into the discussion before IoT had even been properly formulated.

The idea of a self-governing group of machines communicating with one another to serve some purpose evolved from the rise of wireless technologies and communication. Furthermore, microelectromechanical systems (known as MEMS), and the rise of the Internet and microdevices gave birth to such an idea. However, it existed in quite an unstructured form when it came out, requiring a lot of refinement from future studies and research. Furthermore, it’s theories, which had existed way back in the 70s, were labeled as embedded internet or pervasive computing.

IoT is the next big step in M2M communication. As a network of sensors and devices that can number in the billions, and can integrate innumerable people in it, IoT is quite easily the most ambitious M2M technology currently being researched.

Furthermore, IoT’s existence has been labeled by many as a natural extension to existing supervisory control and data acquisition (SCADA) norms. These norms are a category of software applications which are used as process control programs. Gathering data from remote locations in real-time to control both the surrounding conditions and the equipment involved, that’s all possible with IoT.

Another major factor to consider in IoT’s development is the fact that it would not have come to be known to the extent it is now had it not been the Chinese government’s prerogative to include it in their five-year plan in 2010.

How does IoT Work?

The IoT ecosystem consists of a large number of smart devices enabled with web connections that utilize various sensors, embedded processors, and other communication hardware to relay data that they collect from their environments. The data is shared via an IoT gateway or a control device, from where it can either be stored on the cloud for analysis or be analyzed at runtime. Often, the devices are designed to share the analysis with other linked devices which can act on the stimulus. It’s a self-governing system that requires no human involvement.

What Can IoT be Used For

Internet of Things allows the chance to view the information in real-time, in a manner that has never been seen before. Through IoT, a never before seen security and management protocol can arise that will allow you to manage everything with just a few finger strokes no matter where you are sitting. Not only is the system more efficient in time, but it also decreases material waste.

The productivity of businesses is increased and attaching an IoT ecosystem to something like a traffic light management program would reduce mismanagement by a fair amount. From environmental conditions to all kinds of various issues that affect our daily lives, IoT offers solutions that seemed impossible just a few years ago.

IoT Benefits for Commercial Enterprises

IoT offers a number of key benefits to commercial enterprises, which include:

– Unrivaled help in monitoring business operations.

– Strong management that leads to better customer experience.

– Efficiency in both time and money.

– Increase in employee productivity.

– Adapting business models and integrating them.

– Improvement in decision making through stronger data analysis.

– Increase in revenue through more optimized revenue generation.

IoT brings about a change in approach. It makes businesses rethink their priorities and methods, encouraging them to create more effective solutions.

Disadvantages of IoT

IoT does have its fair share of disadvantages. They include:

– The chances of having an entire system hacked increases. As there are a number of devices connected to one another and relying on each through information sharing, loss of integrity is a major risk.

– Management of data will become a major issue since a huge number of devices will have to be managed in conjunction with one another at the same time.

– A single virus can corrupt each device connected by the system.

– A lack of international standards concerning this technology makes it hard to optimize it. Furthermore, making devices connect when they have different manufacturers is not a simple task.

The Internet of Things is perhaps one of the most important research areas currently. The potential it exhibits is fascinating, and its applications highly helpful. While it is not ready to be applied, with its disadvantages being serious and costly, it won’t be long until it makes its way into people’s lives.

A Reference Architecture For The Internet of Things

There are several reasons why a reference architecture for IoT is a good thing:

— IoT devices are inherently connected – we need a way of interacting with them, often with firewalls, network address translation (NAT) and other obstacles in the way.

— There are billions of these devices already and the number is growing quickly; we need an architecture for scalability. In addition, these devices are typically interacting 24×7, so we need a highly-available (HA) approach that supports deployment across data centers to allow disaster recovery (DR).

— The devices may not have UIs and certainly are designed to be “everyday” usage, so we need to support automatic and managed updates, as well as being able to remotely manage these devices.

— IoT devices are very commonly used for collecting and analyzing personal data. A model for managing the identity and access control for IoT devices and the data they publish and consume is a key requirement.
