2. 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.

3. 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

4. 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.

5. 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.

6. 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.,

7. 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.

8.  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.

9. 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.

10. DISADVANTAGES OF PERVASIVE
COMPUTING
 Pervasive Computing is not entirely secure.
 Frequent line connections that are broken.
 Slow Connections.
 Very expensive operating costs.

11. 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.
