Ubiquitous Computing: Computing in Today’s era

Today, our world revolves around machines, computers, Smartphone etc. You admit it or not, we are living in the age of ubiquitous computing. Yes, this is the truth; we are using technical advancements in our day to day life. The word ubiquitous means “existing everywhere” or “present everywhere”. Yes, we are captivated by machines and technologies nowadays. What if I ask you that when you use your Smartphone? The answer will be just a few minutes ago. This conversation proves that we are living in the age of ubiquitous computing. Ubiquitous computing concentrate on creating smart products for communication and exchange of data.

In this article, we will discuss ubiquitous computing, its meaning, history, and other aspects. So, first of all, let’s take a look at what is ubiquitous computing.

Ubiquitous Computing

what is ubiquitous computing

It is the concept of computer science which emphasizes to make the availability of computing anytime and anywhere. It can occur using any device in any form in any location. It is considered as a technological path of innovation. Another word used for ubiquitous computing is pervasive computing. It is the fastest growing trend in order to embed microprocessors in everyday objects so that they can communicate information from one end to another. The devices made using ubiquitous computing are completely connected and are constantly available. Some of the devices that are based on ubiquitous computing are:-

  • Apple watch
  • Amazon echo speaker
  • Amazon EchoDot
  • Fitbit
  • Electronic toll systems.
  • Smart traffic lights
  • Self-driving cars
  • Home automation
  • Smart locks
  • NEST

Ubiquitous computing covers a wide range of research topics such as mobile computing, mobile networking, artificial intelligence, location computing, sensor networks etc. It removes the complexity of computing and increase efficiency while using computing for different activities and focuses on learning.

History of Ubiquitous Computing

The phrase “ubiquitous computing” was coined by Mark Weiser in the year 1988. He was the chief technologist at PARC. Mark Weiser is also known as the father of ubiquitous computing because of his contribution to the concept of ubiquitous computing.

Ubiquitous computing can be implemented into various machines such as television, tablets, mobile phones etc. This technology is advanced enough that allows it to be implemented in household items like mirror, table, refrigerator, windows etc.

Features of Ubiquitous Computing

  • Real-time attributes capturing.
  • It uses economical processors; hence reduce memory and storage requirements.
  • It relies on wireless technology, advanced electronics, and converging internet.
  • As the devices are constantly connected, therefore it increases the surveillance and restrictions in user’s privacy.
  • It places the prototype in human by considering the human factor rather than computing.
  • It is a device that is constantly available and totally connected.
  • Rather than one to one relationship, it concentrates on many to many relationships along with the idea of technology.
  • Ubiquitous computing provides transparent interfaces.
  • It is able to capture live experiences to recall them later.

Advantages of Ubiquitous Computing

  • It is convenient to access relevant information
  • It reduces the complexity of using new technologies
  • It provides you with quick and efficient results
  • It eliminates monotonous tasks by supplementing the environment with interconnected digital technology

Ubiquitous Networking Layers

Pervasive Network Layer

It includes all the networks that are connected directly or indirectly to the internet. The significant sections of pervasive network layer are Server and Gateway.

Ubiquitous Access Layer

It handles network concerns related to the pervasive network. It considers the issues such as network access protocol, service management, and discovery etc.

Ubiquitous Device Layer

It includes a user interactive device that is directly or indirectly interacted. Concerns like smart devices, sensors etc are considered under this layer.

Difference between Ubiquitous Computing and Cloud Computing

In ubiquitous computing, multiple objects are used for accessing the networks and it describes a computer not as a self-contained object. Ubiquitous computing is the part of our daily life form simple to complex tasks. On the other hand, cloud computing does not put the computer anywhere but it gives access to computer everywhere. It does not break with a traditional computing system.

Application of Ubiquitous Computing

  • Communication
  • Logistics
  • Motor traffic
  • Military
  • Production
  • Smart homes
  • E-commerce
  • Inner security
  • Medical technology

Hence, ubiquitous computing has a great impact on our day to day life. It provides convenience to our communication system. It focuses on making smart environment by using microprocessors in everyday objects for communication. As the word suggests ubiquitous computing is present everywhere.
