Cloud Offload in Hostile Environments

Abstract

Selective offloading of resource-intensive execution from a mobile device to the cloud can extend battery life and broaden the range of supported applications. Unfortunately, the success of this approach is critically dependent on a reliable end-to-end network. This dependence is a serious vulnerability in hostile environments especially those involving wireless components in their long-haul network segments. We describe an architectural approach to reducing this vulnerability. Using a hierarchical cloud structure, offload is performed on stateless elements that are typically one wireless hop away from a mobile device. The proximity of offload reduces synchronous dependence on vulnerable long-haul network segments. We present experimental results that reflect on key design tradeoffs from a prototype implementation of this architecture.
