Performance and Scalability Analysis of SDN-Based Large-Scale Wi-Fi Networks

The Software-Defined Networking (SDN) paradigm is one that utilized frequently in data centers. Wireless Networking, often known as SDWN, refers to an environment which concepts from SDN are implemented wireless networks. SDWN struggling with challenges of scalability and performance a result the growing number networks its coverage area. It thought techniques, such Mininet-Wi-Fi Ryu Controller for networks, can overcome problems performance. Existing Wi-Fi systems do not provide execution end clients, reason why capability restricted on architecture. Within scope this study, we analyzed operating using Transmission Control Protocol (TCP) User Datagram (UDP). By utilizing testbed consisting Mininet-Wi-Fi, were able test over evaluate addition scalability. When evaluating network, take into account different metrics, bandwidth, round-trip time, jitter. In order assess level performance, SDN-based controller linked increasing access points (1, 2, 3, 4) well stations (10, 30, 50, 100). experimental findings obtained indicate dependability network provided by environment. addition, time TCP packets grows proportionally hops involved. A single point capable simultaneously supporting up fifty people at once.
