The Next Evolution of the Internet is Changing Everything
The Internet of Things (IoT) is going to change almost everything — including us. This may sound audacious, but we can already see the far-reaching impact the Internet has had on education, communication, business, science, government, and the way people connect with each other. While the Internet is one of the most powerful and revolutionary developments in human history, we are about to see the next big leap in its evolution – IoT.
Why is IoT Important?
IoT is the next big thing. It heralds a new age marked by the invention of revolutionary applications that dramatically improve the way people live their lives, and the way they work and entertain themselves. It represents a higher level of awareness of our environment, an ability to monitor reactions to different conditions and enables smarter and quicker responses. For example, you walked out of the door without keys in your pocket. Your smart door beeps that you are leaving without keys, giving you the chance to go inside and pick them. Similarly, if you have a fire at home and you are sleeping, your smoke detector sends a signal to the local fire station. There are many real-life examples where IoT can be used to drastically improve your personal and work lives.
In order to realize the real value of IoT applications, there is a need for a new architecture that ensure interoperability among various IoT entities.
There are a number of technologies that support IoT. The architecture below describes how various technologies communicate the modularity and configuration of IoT deployments.
This layer is the lowest layer created by smart objects and integrated with sensors. The sensors are responsible for the interconnection of the physical and digital worlds which allows real-time information to be collected and processed.
Gateways and Networks
A highly durable and resilient network infrastructure is required as a transport medium because it needs to convey the vast amounts of data produced by these tiny sensors.
Management Service Layer
This layer processes information through analytics, process modelling, security controls, and device management.
There are various applications from industry sectors that can leverage IoT. Applications can be specific to a particular industry sector, and some applications such as Fleet Management, Asset Tracking, and Surveillance can cut across multiple industry sectors.
The IoT architecture is not only helpful in interpreting the relationship between IoT and real world, but it is also beneficial in the implementation of IoT in its current development milieu.
