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.
