Performance Evaluation of Domain Isolation Algorithm Using Mininet-WIFI

Today's digital world is influential in every aspect, making people want to change things to be more practical. There is a high demand for using WiFi technology in every sector. The highest impact on network infrastructure planning was developed by the Software-Defined Network (SDN) to address all the complex problems and connectivity needs of the future. The connectivity needed in the future is something new that can be developed so that the network can better adapt to dynamic conditions and increase flexibility. Thus, the support of WiFi technology on SDN networks became a dream, and this paper aims to implement a domain isolation algorithm (DI) to be applied to WiFi networks on the SDN. The algorithm allows for the acquisition and transmission of packets between end devices using the network's shortest and least congested pathways. Furthermore, we assessed the effectiveness of the employed algorithm by evaluating their performance based on different quality of service (QoS) metrics, utilizing the iPerf tool. The experimental results demonstrate that the proposed system achieved favorable outcomes in quality of service (QoS) metrics.
