| Summary: | Two proposed cognitive selection mechanisms were applied in user terminal to
observe the performance of the mechanisms when executed within wireless
environment. In this study, three different wireless broadband connections were
used. They are high speed packet access (HSPA), wireless fidelity (WiFi), and
wireless interoperability for microwave access (WiMAX). These two proposed
cognitive selection mechanisms are termed as successive and comparative
selection. The cognitive elements that are being utilized in the selection system
include the capability of sensing the network condition (i.e. actual connection
speed), performing analysis and decision making for selecting the most optimum
condition. Successive selection performs an active monitoring with the time
interval that had been established as 1800 seconds. Similar active monitoring
process occurs in comparative selection. However, a threshold value is assigned
as the set off point each time the mechanism is executed. The empirical study was
conducted by devising the two cognitive selection mechanisms into two different
locations i.e. the office and residential area. These locations were selected to vary
the evaluation of the performance of these selection mechanisms in terms of
connection switch delay and optimized speed. These two analyses were carried
out by evaluating based on the actual connection speed and the recorded time
delay. It was found that successive selection had shown a better optimized speed
performance as compared to comparative selection. Low delay performance was
the result of employing comparative selection in the system. |
