Stratus enables efficient connectivity to mobile devices by reducing bytes transferred as well as saving energy during cellular data communication. Stratus leverages resources in the cloud to achieve energy savings by modulating incoming and outgoing data traffic to better adapt to the energy characteristics of the cellular interface. The optimizations include message aggregation, asymmetric data compression, and opportunistic packet scheduling based on dynamically varying signal quality.
