| Summary: | The evolution of communication device demands
for faster connection and higher data rates. This results in
proliferation of new broadband technologies that are being
introduced into the market for each interval of every 2 to 3
years. However, these technologies are still facing the challenge
of unsatisfied users who request not only faster connection but
also reliable connectivity. This paper proposes two cognitive
selection mechanisms termed as successive and comparative
selection which are applied in multiple broadband user
terminals in order to maintain good connection rate. By
employing such mechanisms, we can observe their
performances in terms of optimized speed and switching delay.
Cognitive radio aspects are also introduced within the selection
system. These include sensing network condition capability,
performing analysis and decision making for selecting the most
optimum broadband network. The empirical study was
conducted within the indoor environment of a residential area.
The location was selected to vary the evaluation of the
performance of these selection mechanisms. It was found that
successive selection had shown a better optimized speed
performance up to 37% improvement as compared to
comparative selection. However, comparative selection shows a
low switch delay performance in contrast to successive
selection. |
