Abstract: Selecting and deploying an appropriate wireless sensor network (WSN) is an important challenge in IoT system design. Evaluating different WSN configurations through physical deployment can be costly and time-consuming. This study proposes a simulation-driven framework that integrates a simulated WSN with an MQTT-based IoT communication infrastructure to enable network-aware performance evaluation prior to physical deployment. An SDN-WISE-based WSN was implemented using the Cooja simulator, and the generated sensor traffic was forwarded to a Mosquitto-based MQTT cluster via a socket-based integration mechanism. Unlike conventional approaches that use independent traffic generators, the MQTT workload in the proposed framework originates directly from the simulated WSN. Experiments with 24-, 36-, and 48-node scenarios showed that average end-to- end delay increased from 37.51 ms to 138.01 ms, while total application throughput increased from 142.51 bps to 281.12 bps. Packet delivery remained effectively near 100% across all scenarios. The proposed approach provides a controlled, repeatable environment for evaluating various WSN configurations and can reduce the need for multiple physical deployments in the early stages of IoT system design.
