connected cars and mobility services Launched in January 2018 as a NPO in the U.S. AUTOMOTIVE MOBILE COMMUNICATION CLOUD & BIG DATA ANALYTICS APPLICATION & SERVICES Members as of September 2020
limited • Demand for communications and application processing between vehicles and edge cloud drastically changes by time and location • Significant delays and service outages may occur in the event of sudden local spikes in demands Challenges in Edge Cloud Application - Our Perspective
the problem • In this talk, two approaches are presented • Simple implementation and experimental results to check the feasibility of the approaches (1) Scale-out to adjacent edge clouds (2) Vehicle data upload control
Measure the number of vehicles connected to the edge cloud in real time • Adjust the amount of data sent from the vehicles according to the number of connections edge edge High data upload frequency High video resolution Low data upload frequency Low video resolution
App Data Upload Control App • Prepared mobile network (LTE) emulation environment to provide MEC • with COMAC (ONF’s open source project) https://www.opennetworking.org/reference-designs/comac/ • Two applications (data upload control app, video recognition app) deployed as MEC applications • Data upload control application • Video recognition app (just as an example) Central Office MME HSS COMAC software based emulation MEC Applications
Data Upload Control App Central Office MME HSS (1) Notify # of current connected vehicles (2) Request vehicles to adjust upload data size by changing upload frequency and video resolution (3) Send recorded video from all vehicles to video recognition app
edge application (face recognition app) was measured when the number of vehicle connections was increased by one every 40 seconds • It was confirmed that the traffic into the edge app remained constant Note: This graph should be used as just one example only because the emulation software was unstable during the experiment, that might affect data.
Source Accelerates Innovation! • In the past, we needed the help of carriers and telecom equipment vendors to conduct these kind of experiments • With the open networking technologies, end users like us can now build and experiment with mobile networks on our own
• How edge computing is expected to be the technology to solve the challenges • Challenges in realizing automotive edge computing • Possible approaches and simple implementations
