Daknet is an ad-hoc wireless network that provides digital connectivity in developing nations using mobile access points mounted on vehicles like buses and bikes, as well as stationary kiosks located in villages. It functions as a store-and-forward system, using the vehicles to transport data between kiosks and a central internet hub. This allows for low-cost asynchronous communication of services like email and bulletin boards without requiring constant connectivity. Daknet is currently deployed in initiatives in India, Cambodia, and elsewhere to provide rural connectivity.

3. Introduction
Daknet, whose name derives from
the Hindi word “Dak” is an ad hoc
network , using wireless technology
to provide digital connectivity.
It combines a physical means of
transportation with wireless data
transfer to extend the internet
connectivity provided by a central
uplink or hub.

4. Why Daknet?
Provide non real-time infrastructures and
applications such as voice mail, e-mail, and
electronic bulletin boards.
Provide store- and forward or asynchronous
modes of communication that is significantly
lower in cost and do not necessarily sacrifice
the functionality required to deliver services.
Simpler to add in a device to the system.
Low maintenance cost.

5. AD-HOC NETWORK
An ad-hoc wireless
network is a collection
of wireless mobile
hosts forming a
temporary network
without the aid of any
established
infrastructure or
centralized control.

6. Daknet Network Architecture
The main parts of a
daknet architecture
are:
->Mobile access
-> point
-> Hub
->Kiosk

7. Mobile Access Point
Daknet travels data over short point to point links between
kiosks and portable storage devices called mobile access
points.Mobile Access Point is mounted on and powered by a
bus or motorcycle, or even a bicycle with a small generator.
MAPs are installed on vehicles that normally pass by each
village to provide store-and-forward connectivity.

11. Hub
It is a common connection point for devices in a network. It is
used to connect segments of a LAN. It contains multiple ports.
Packet at one port copied to all other ports-all segments see
all packets. When the vehicle passes near an internet access
point –the hub- it synchronizes all the data from different
kiosks using the internet.

12. Kiosk
It is a booth providing a computer related
service such as ATM. In each village there is
kiosk. It enable user to enter and display
information on the same device. Either
directional or omni directional antennas are
located at each of the kiosks or hubs.

13. WiFi Cards
In Daknet a wireless card i.e wifi card is
mounted on a vehicle that travels around to
remote villages and exchanges updated
information with each kiosk it encounters
through WiFi.

14. Advantages of using WiFi cards
• Increase mobility
• Cost for setting up a network is much less than
running wires.
• WiFi has a global set of standards.
• support encryption in order to protect the
data that is being transmitted.

15. How Daknet works

16. Daknet In Action
Daknet is currently in
action in many places.
They are,
• Bhoomi initiative in
Karnataka
• SARI (Sustainable
Access for Rural India)
project of Tamilnadu
• Ratnakiri project in
Cambodia

18. Features of DakNet
• Since it avoids using phone lines or expensive
equipment, Daknet provides one of the
lowest-cost accessibility solutions in the
world.
• The same hardware, software and user
interface can be used to enjoy real-time
information access.
• It has the ability to provide a seamless
method of upgrading to always -on broadband
connectivity.

19. CONCLUSION
DAKNET IS GOING TO BE DEPLOYED AND TESTED
IN LARGER IMPLEMENTATIONS WITH
APPLICATIONS THAT EXPLOIT IN BRAODBAND
CAPABILITIES.
THE CURRENT R&D FOCUS IS ON FURTHER
LOWERING THE COSTS OF THE REQUIRED AND
DEVELOPING A HIGHLY INTEROPERABLE AND
CROSS PLATFORM SOFTWARE MODULE AO THAT
DEPLOYEMENT PROCESSES CAN BE
STREAMLINED.
