Digital Twin Migration using the OKD platform: A Use-Case for Emergency Vehicles

The compute capabilities in modern vehicles are on the rise, resulting in increasingly advanced driving assist features accompanied by increased vehicle costs. To reduce cost while providing similar assistance features, research in autonomous vehicles has focused on cooperative scenarios where mobile entities with sensing capabilities share their knowledge and are supported by the roadside infrastructure that provides computing, storage and network resources. We present a use case for container migration on edge networks to reduce application downtime concerning autonomous emergency response vehicles and their coordination in the field. To provide lower communication delay and faster access to data, the digital twins of the vehicles are implemented as containers placed at network edge nodes. By measuring the time necessary to perform a complete migration of a running container to a different edge node, while keeping its execution state, we attained the goal of keeping application downtime low through container migration and identifying possible improvements to the system.
