Daknet

Why Daknet?

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.

Daknet In Action

Villagers in India and Cambodia are using Daknet with good results. Local entrepreneurs currently are using DakNet connections to make e-services like e-mail and voice mail available to residents in rural villages. One of the Daknet's early deployments was as an affordable rural connectivity solution for the Bhoomi e-governance project. DakNet is also implemented in a remote province of Cambodia for 15 solar-powered village schools, telemedicine clinics, and a governor's office.

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).

Disadvantages Of Wifi

The 802.lib and 802.llg flavors of Wi-Fi use the 2.4 GHz spectrum, which is crowded with other devices such as Bluetooth, microwave ovens, cordless phones (900MHz or 5.8 GHz are therefore, alternative phone frequencies one can use if one has a Wi-Fi network), video sender devices, among many others. This may cause degradation in performance. Other devices, which use microwave frequencies such as certain types of cell phones, can also cause degradation in performance.

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.

Kiosk

It is a booth providing a computer related service such as ATM. In each village there is kiosk. It requires a user interface that can be used without training. It enable user to enter and display information on the same device.

Mobile Access Point

Daknet offers data to be transmitted over short point-to-point links. It combines physical and wireless data transport to enable high-bandwidth intranet and internet connectivity among kiosks (public computers) and between kiosks and hubs (places with reliable Internet connection). Data is transported by means of a mobile access point, which automatically and wirelessly collects and delivers data from/to each kiosk on the network.

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. Ad-hoc networks require a peer-to-peer architecture, and the topology of the network depends on the location of the different users, which changes over time. In addition, since the propagation range of a given mobile is limited, the mobile may need to enlist the aid of other mobiles in forwarding a packet to its final destination. Thus the end-to-end connection between any two mobile hosts may consist of multiple wireless hops.

About

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.

Conclusion

Daknet's low deployment cost and enthusiastic reception by rural users has motivated dozens of inquiries for further deployments. This provides millions of people their first possibility for digital connectivity. Increasing connectivity is the most reliable way to encourage economic growth.
