Abstract :
In this paper, we conducted an experiment using a PC to evaluate the proposed novel selection policy for a communication system in heterogeneous wireless networks. It entailed the use of an analytic hierarchy process (AHP) algorithm that took the mobility of the user terminals into account. In particular, the AHP algorithm demonstrated an excellent improvement in overall performance with existing wireless systems. We confirmed the performance improvement by applying the AHP under the conditions where Wi-Fi and WiMAX were operating in heterogeneous wireless networks. The experimental results showed that the proposed policy using AHP provided a total amount of uploaded data that was 1.3-fold higher than WiMAX, 1.28-fold higher than Wi-Fi and 1.14-fold higher than conventional modes. AHP also provided almost full connection duration.
