Abstract
Nowadays
certain
centres
of rural
population
are experimenting
difficulties
to access
high-speed
telecommunication
networks.
This
phenomenon
avoids
the possibility
of accessing
to the digital
revolution
for
such
areas.
The private
companies
are focusing
their invest
ment
efforts
in other
more
profitable
areas.
In such
conditions,
the governments
have
to promote
alternatives
to bridge
the digital
divide
between
rural
and urban
areas.
We present
how
ring-tree
topologies
can be used
as an adequate
architecture
to incorporate
such
less
favoured
areas
in the Information
Society.
We present
a
case study
for Andalucia
(a wide
region
in the south
of
Spain)
where
a decision
support
system
based
on a genetic
algorithm
is implemented
providing
cost effective
solutions.
We make
use of real life data from
the telecommunication
industry
and present
different
solutions
separated
by coverage
as well as a sensitivity
analysis
based
on the main
factors
of the cost function.Ministerio de Ciencia y Tecnología TIC2003 -04784-C02-0
