In an era marked by the rapid growth of the Internet of Things (IoT), the inventing of smart devices brings along the need for a good communication protocol to ensure interoperability. This paper works under the theme of performance evaluation of Matter-enabled and non-Matter-enabled IoTs over latency and throughput in some network environments. We use two devices—a Matter-compatible and a non-Matter—to perform multiple experiments that compare communication efficiency under various network conditions. The problem addressed here is the performance disparity between Matter and non-Matter devices in terms of latency and throughput in exchanging data, with a focus on personal WLAN network and real WLAN. Our findings, therefore, provide insight into the interoperability and reliability of Matter technology for heterogeneous IoT networks but with practical considerations for use in mixed environments with multiple protocol requirements. The optimum network configurations that maximize device response and data handling capacity make it clear how Matter is likely to deliver improved performance and scalability across diverse IoT ecosystems.
