WHAT IS PERVASIVE COMPUTING?

Pervasive means “EXISTING EVERYWHERE”

Pervasive computing embodies the future of network computing

enabling wireless communication between individuals and computing

devices and between devices itself.

Pervasive Computing devices are tiny, invisible microprocessors

embedded in any type of objects like clothes,home,cars,watches etc.,

Also known as Ubiquitous Computing.

PERVASIVE NETWORKING

Pervasive networking is the ability for devices to

autonomously arrange themselves into local networks and

exchange information through these networks.

Components of Pervasive networking: Pervasive

Network Layer

Pervasive Access Layer

Pervasive Device Layer

Pervasive Human Machine Interaction Layer

Pervasive Human Core Layer

LAYERS OF PERVASIVE NETWORKING

Pervasive Network Layer

This layer includes all networks and the networks

are connected directly or indirectly to the internet. Server

and Gateways are the important parts in this layer.

Pervasive Access Layer

This layer deals with pervasive network connection

issues. Issues considered in this layer are Service

Discovery and Management, network access protocols.

LAYERS OF PERVASIVE NETWORKING

Pervasive Device Layer

This layer includes all user interactive devices

whether they are interacted directly or indirectly. Issues

considered in this layer are Sensors and Smart Devices.

Pervasive HMI Layer

This layer deals Human interaction with all

network accessed devices.

LAYERS OF PERVASIVE NETWORKING

Pervasive Human Core Layer

This layer is the inner layer of the Pervasive

networking. Issues in this layer are based on the various

applications. Applications considered for human core

layer are such as Health care, smart home, business

application etc.,

TELE-HOME HEALTHCARE SYSTEM

It monitors the health states of people in Health care

System. The monitoring information should be reported

to the Hospital Service center. If there is an emergent

incident it should detected and reported to relatives,

Emergency Health care System.

If the home cared Family member has any Emergency

Health Problems, the HMI & Service Management will

inform the Hospital Service center, Community

emergency center and relatives by SMS at the same

time.

ADVANTAGES OF PERVASIVE COMPUTING

Manage information quickly, efficiently and effortlessly.

Smart Environments will be embedded with computing

technologies that will be mostly out-of-sight

Removes complexity of new technologies.

Convenient access to relevant information stored on

networks, allowing them to easily take action anywhere,

anytime.

Environment will be supplemented with interconnected

digital technologies. Interconnectivity will eliminate

mundane tasks.

DISADVANTAGES OF PERVASIVE COMPUTING

Pervasive Computing is not entirely secure.

Frequent line connections that are broken.

Slow Connections.

Very expensive operating costs.

CONCLUSION

Removal of wires in the network computing available to

everyone everywhere.

Information can be accessed when and where it is

needed

But still Privacy and Security major drawbacks of the

Pervasive Computing.
