Several IoT systems demand real-time communication, introducing timing constraints on data transmission and stressing the network message propagation. Many of these systems should address these communication requirements, considering the use of wireless networks, which still represents an open issue. To address this communication scenario, it is crucial to employ dynamic configuration strategies that can swiftly adapt the network behavior, ensuring stability and preventing failures under certain operational conditions. Therefore, to rely on mechanisms to implement software-defined networks (SDN), considering wireless real-time communication, is necessary to support these applications. This paper builds on the author’s previous work and shows how to implement software-defined networks that dynamically accommodate the real-time traffic requirements in a wireless network. The network model was implemented and evaluated using the NS-3 simulator. The experimental results demonstrate that incorporating SDN policies into wireless networks enhances the predictability of these systems. The implemented NS-3 libraries were made public and available for researchers and developers. They can utilize these libraries to model and evaluate specific software-defined wireless networks.
