## 6.4  Use Cases & Frameworks Mapping

This section provides a synthesis of the previously identified use cases and the architectural features of the MEC and oneM2M frameworks. It maps each use case to the relevant framework components and functionalities, showcasing how MEC and oneM2M support specific operational needs. The mapping highlights the alignment between the frameworks and the identified scenarios, while also pointing out areas where enhancements or additional integration mechanisms may be required to better support cross-domain use cases.

- This is one of the most common deployment scenarios that use cloud based IoT platforms and edge computing.
- Although some of the benefits of edge computing can be achieved through network and processing, the advantages of 100% edge computing are not fully utilized because the cloud remains the final endpoint where data is stored and managed.

he “Vulnerable Road Users” (VRU) use case shares deployment characteristics with the “Autonomous Vehicle with Continuous Edge Computing” scenario, where achieving ultra-low latency, localized processing, and context awareness is critical. This is necessary to effectively process data from nearby roadside units, sensors mounted on traffic signals, and other urban infrastructure to enable real-time analytics and immediate response. To support this, specific processing tasks can be offloaded to oneM2M Edge Instances (MN-CSEs) operating close to the data sources. As vehicles and VRUs dynamically move across different geographic zones, coordination across multiple MEC nodes becomes essential. Therefore, a centralized IN-CSE deployed in the cloud is ideal for maintaining global context, orchestrating and synchronizing edge instances, and ensuring uninterrupted service continuity. Meanwhile, MN-CSEs should be deployed close to the edge to provide low-latency decision support
