Talk Description:
In wide-area distributed systems based on 5G and Beyond 5G mobile communication systems, we can now flexibly utilize computing resources deployed in the network such as MEC (Multi-Access Edge Computing) servers. However, constructing a high-quality IoT system is still challenging, e.g., dealing with a wide variety of devices, various types and amounts of data, and different processing methods.

We are developing an IoT platform in Elixir, named "Giocci".
This platform realizes the features below to empower developers.
1) Transparent use of computing resources (edge-side, MEC, cloud)
2) Node-to-node access methods
3) Data storage and sharing

This talk will introduce you to the Giocci world.
- Giocci's concept and architecture
- The efficient inter-node communication derived from Zenoh
- The motivational example application for Giocci that employs an object detection model (YOLOv3) running on SRv6 MUP in the commercial 5G network powered by SoftBank

We aim to discuss Elixir and BEAM's potential in developing wide area distributed IoT systems.

2. 2 Who we are?? @takasehideki Associate Professor The University of Tokyo @kikuyuta Project Professor Kochi University of Technology @matsusato3 Technical Meister SoftBank Corp. @ShintaroHosoai @nishiuchikazuma
3. 3 MEC MEC Interaction of Functions = Comm. between Things By organizing the cluster of computer resources, processes can be interacted with and operated! Functional Paradigm ＝ IoT!! Why “Elixir for IoT??”
4. 4 • More and more system configurations Local Edge Client Develop Edge-Client, Server, MEC, Cloud ・Spec ・OS ・Language ・Cloud-Service Configuration Connected Network Local, Mobile, WAN, Leased circuit Communication Protocol Serial, http(s), MQTT, ROS, WebSocket REST API, gRPC, FTP, SMTP ・・and more Cloud Server Leased circuit Edge Client WAN Cloud Mobile Cloud MEC MEC Server Challenge in IoT Development

9. 9 Scalable decentralized and routing Eloquent pub/sub, storages, query, and queryables Fast lightweight and easy to use After that, Our answer is,,,
10. • Zero Overhead Pub/Sub, Store/Query and Compute −Zero network overhead protocol −DDS-like communication within a network and MQTT-like communication between networks −Dev leader: ZettaScale Technology Ltd. −GitHub: eclipse-zenoh/zenoh • Four important features ① Very lightweight! ② Scalable to NW structure! ③ Runs Everywhere! ④ Interoperability with others! 10 What is??
