DakNet is a wireless network that provides internet access to remote villages in India and Cambodia using a store-and-forward technique. It transmits data between kiosks and mobile access points (MAPs) mounted on vehicles. MAPs come within range of kiosks or internet hubs to transfer messages and videos. DakNet leverages low-cost wireless and digital storage to provide affordable connectivity without real-time requirements. It has been successfully deployed to provide education, healthcare, government services, and commerce to rural communities in a scalable way.

3. INTRODUCTION
 DakNet is an internet service based on the technology, which was
spun-off from an idea, known as DonkeyNet.
 DakNet is an ad hoc network which uses wireless technology to
provide digital connectivity.
 It uses a store and forward technique through Wi-Fi, which is
described as "Cached Wi-Fi Intelligence”
 DakNet, derives from the Hindi word for “post” or “postal,”

4. Mobile Ad hoc Connectivity
 DakNet wireless network takes advantage of the existing communications
and transportation infrastructure.
 DakNet transmits data over short point-to-point links between kiosks and
portable storage devices, called mobile access points (MAPs).
 Mounted on and powered by a bus, a motorcycle, or even a bicycle with a
small generator
 The Daknet operation thus has two types:
 MAP-equipped vehicle comes within range of a village WiFi- enabled
kiosk
 MAP-equipped vehicle comes within range of an Internet access point
(the hub)

6. Seamless Scalability
 In addition to its tremendous cost reduction, a critical feature of DakNet
is its ability to provide a seamless method of upgrading to always-on
broadband connectivity.
 The only change is the addition of fixed-location wireless antennas and
towers—a change that is entirely transparent to end users because they
need not learn any new skills or buy any new hardware or software.
 DakNet makes it practical for individual households and private users to
get connected.

7. Daknet in Action
 Villages in India and northern Cambodia are actively using DakNet with
good results.
 One of DakNet’s earliest deployments was as an affordable rural
connectivity solution for the Bhoomi e-governance project.
 In September 2003,we also implemented DakNet in a remote province of
Cambodia for 15 solar-powered village schools, telemedicine clinics, and
a governor’s office.

10. Myths And Truths
 Myth : The village telephone is the best model for poor
communities.
Truth : Giving everyone access to digital messaging is better
than installing a community telephone.
 Myth :Poor people don’t need computers.
Truth : The poor not only need digital services, but they are
willing and able to pay for them.

11. Daknet’s network architecture
 The main parts of daknet architecture are:
 Mobile access point
 Hub
 Kiosk
11

12. How It Works?
 DakNet transmits data over short point-to-point links between kiosks
and portable storage devices, called mobile access point(MAPs).
 MAP physically transports data
 DakNet Mobile Access Point (MAP) Networks require:
 Appropriate Environment: computers in remote villages that can be
accessed by road transport.
 Approach: MAPs are installed on vehicles that normally pass by each
village to provide store-and-forward connectivity

 “Daknet” allows rural villages to exchange messages and video through
a mobile ISP.
 Villagers are able to send message and record videos through these
kiosks.
 All information is downloaded to the central system at the office station.

15. Advantages & Disadvantages
of daknet
Real-time communications not required for public
kiosks
 1. Communications tend to be asynchronous
 2. Villager’s trade –off latency for affordability
Leverages two major trends
 1. Cost of wireless broad (WiFi)
 2. Cost of digital storage
15

16. Contd..
 Easy to implement on widespread basis
 Lower uplink costs and maintenance
requirements
 Bandwidth does not decrease with distance
 Seed infrastructure that is scalable with demand
 Reduced regulatory challenges and licensing fees
16

17. Disadvantages
 Token ring constraint if a lower tier goes down, all
higher tier goes down
 Experience and Expertise person can only handled
kiosk
 Efficiency of bandwidth reduced for each tier

18. APPLICATIONS
 EDUCATION
 TELEMEDICINE
 E-GOVERNMENT
 E-COMMERCE

19. Conclusion
 DakNet’s low deployment cost and its enthusiastic reception by rural
users has motivated dozens of inquires for further deployments.
 The larger goal is to shift the policy focus of the government’s
universal-service-obligation funds from wire line village telephones to
wireless ad hoc networking.
 Country wide connectivity through Daknet.
