A high-quality ecosystem plan may signify a milestone in the development of smart living. The Internet of Things (IoT) is the key to establishing a high quality ecosystem. This study developed an IP Multimedia Subsystem IoT architecture for ecosystem applications. The proposed traffic grouping mechanism will group dynamically attach request signaling by agent-based operations to reduce network congestion possibility and to enhance system Service Level Agreement. The Electronic Product Code Information Services platform is implemented and evaluated in a field trial. Performance analyses of the proposed architecture confirm that it can achieve a high-quality ecosystem in terms of CPU utilization and platform performance optimization.
