The rise of IoT-connected gadgets has resulted in a deluge of information.
Network bandwidth is heavily used due to the large amount of data being delivered to
the cloud or fog. The IoT network could be vulnerable to network congestion.
Furthermore, some IoT implementations need multimedia data transmission with
various Quality of service (QoS) standards. Multinetwork information architecture
(MINA) aims to satisfy various QoS criteria for different areas of IoT. While it can
adapt to new network conditions, it cannot provide the quality of service required for
critical IoT applications. This study proposes enhancing the software-defined networkbased IoT network with the application-aware QoS routing algorithm (AQRA) and
MINA to guarantee a wide range of quality-of-service (QoS) requirements for critical
IoT applications. The best possible outcome was achieved by using the particle swarm
optimization (PSO) method.
