 ### Computational Offloading
 
-An edge computing use case where tasks are offloaded from an edge device to the infrastructure edge for remote processing. Computational offloading seeks, for example, performance improvements and energy savings for mobile devices by offloading computation to the infrastructure edge with the goal of minimizing task execution latency and mobile device energy consumption. Computational offloading also enables new classes of mobile applications that would require computational power and storage capacity that exceeds what the device alone is capable of employing (e.g., untethered Virtual Reality). In other cases, workloads may be offloaded from a centralized to an edge data center for performance.
