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,”

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)

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.

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.

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.

DAKNET’S NETWORK ARCHITECTURE

The main parts of daknet architecture are:

Mobile access point

Hub

Kiosk

Architecture

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

CONTD.. “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

DAKNETReal-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

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

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.
