Pervasive Computing Infrastructure

PERVASIVE COMPUTING

Introduction:

Our life in the future should be very carefree with little to no hassle.

Less searching, faster and accurate access to information, when needed.

Time and location boundaries will eventually be eliminated, resulting in a true information age style of civilization.

Future devices will become more and more intelligent; they will start to talk among themselves to serve us better.

PERVASIVE COMPUTING INFRASTRUCTURE

The aim of ubiquitous computing is to design computing infrastructures in such a manner that they integrate seamlessly with the environment and become almost invisible. The essence of that vision was the creation of environments saturated with computing and communication capability, yet gracefully integrated with human users.

Pervasive – all around us

     Should be there where we need them  

     Not go and get them

Human Centred

     Computers should adapt to the humans

     Computations enter our world

Must be unobtrusive and minimize user distraction

Computers as we know it will disappear

Better ways of Computer-Human interaction

The computers need to be aware of humans – Context

Pervasive computing integrates computation into the environment, rather than having computers which are distinct objects.

Other terms for pervasive computing:

 Ubiquitous computing

 Calm technology

 Things that think

 Pervasive internet

 Ambient intelligence

Proactive computing

Augmented reality

Sentient Computing

Urban Computing

Ubiquitous Computing

 3 Artificial intelligence.

 Ubiquitous computing (ubicomp) integrates computation into the environment, rather than having computers which are distinct objects.

 Promoters of this idea hope that embedding computation into the environment 

 Everyday objects would enable people to interact with information-processing devices more naturally and casually than they currently do, and in ways that suit whatever location or context they find themselves in.

 Ubiquitous computing encompasses wide range of research topics, including distributed computing, 

 Mobile computing

 Sensor networks

 Human-computer interaction

Pervasive – diffused among us

It will make information available everywhere

Ubiquitous – State of being everywhere

The most important characteristics of pervasive environments are:

Heterogeneity: Computing will be carried out on a wide spectrum of client devices, each with different configurations and functionalities.  

Prevalence of "Small" Devices: Many devices will be small, not only in size but also in computing power, memory size, etc.  

Limited Network Capabilities: Most of the devices would have some form of connection. However, even with the new networking standards such as GPRS, Bluetooth, 802.11x, etc., the bandwidth is still relatively limited compared to

wired network technologies. Besides, the connections are usually unstable.   High Mobility: Users can carry devices from one place to another without

stopping the services.
