Abstract

DakNet is a patented wireless package that does away with base stations. DakNet offers a cost-effective network for data connectivity in regions lacking communications infrastructure. Instead of trying to relay data over long distances, which can be expensive, Daknet transmits data over short point-to-point links between kiosks and portable storage devices called Mobile Access Points (MAP).

Description of Daknet

Now a day it is very easy to establish communication from one part of the world to other. Despite this even now in remote areas villagers travel to talk to family members or to get forms which citizens in-developed countries an call up on a computer in a matter of seconds. The government tries to give telephone connection in very village in the mistaken belief that ordinary telephone is the cheapest way to provide connectivity. But the recent advancements in wireless technology make running a copper wire to an analog telephone much more expensive than the broadband wireless Internet connectivity. Daknet, an ad hoc network uses wireless technology to provide digital connectivity. Daknet takes advantages of the existing transportation and communication infrastructure to provide digital connectivity. Daknet whose name derives from the Hindi word "Dak" for postal combines a physical means of transportation with wireless data transfer to extend the internet connectivity that a uplink, a cyber café or post office provides.Real time communications need large capital investment and hence high level of user adoption to receiver costs.

The average villager cannot even afford a personnel communications device such as a telephone or computer. To recover cost, users must share the communication infrastructure. Real time aspect of telephony can also be a disadvantage. Studies show that the current market for successful rural Information and Communication Technology (ICT) services does not appear to rely on real-time connectivity, but rather on affordability and basic interactivity. The poor not only need digital services, but they are willing and able to pay for them to offset the much higher costs of poor transportation, unfair pricing, and corruption. It is useful to consider non real-time infrastructures and applications such as voice mail, e-mail, and electronic bulletin boards. Technologies like store- and forward or asynchronous modes of communication can be significantly lower in cost and do not necessarily sacrifice the functionality required to deliver valuable user services. In addition to non real-time applications such as e-mail and voice messaging , providers can use asynchronous modes of communication to create local information repositories that community members can add to and query.

HOW DAKNET WORKS

A simple store-and-forward WiFi system, using a government bus as a central linkage. The bus contains a simple WiFi installation and server, and when in range of one of the outlying information kiosks it synchronizes data for later processing.

DakNet is a patented wireless package that does away with base stations. DakNet offers a cost-effective network for data connectivity in regions lacking communications infrastructure. Instead of trying to relay data over long distances, which can be expensive, Daknet transmits data over short point-to-point links between kiosks and portable storage devices called Mobile Access Points (MAP). Mounted and powered on a bus or motorcycle with a small generator MAP physically transports data between public kiosks and private communications devices and between kiosks and a hub (for non real time internet access). Low cost Wi-Fi radio transceivers transfer data stored in MAP at high bandwidth for each point-to-point connection.
