OSCAR: a deployable adaptive mobile bandwidth sharing and aggregation system

The exponential increase in mobile data demand coupled with the rapid deployment of various wireless access technologies have led to the proliferation of multi-interface enabled devices. As a result, researchers focused on exploiting the available interfaces on such devices in both solitary and collaborative forms. Unfortunately, the proposed systems, that exploit these interfaces, face a formidable deployment barrier. Therefore, in this work, we present OSCAR, a system that exploits multiple network interfaces on modern mobile devices. OSCAR provides a set of mechanisms for sharing bandwidth across multiple collaborating devices and enables this collaboration by providing users with sharing incentives. We present an overview of the system coupled with the OSCAR scheduler. We evaluate OSCAR via implementation on Linux and compare our results to the current optimal achievable throughput. Our preliminary results shows that in the throughput maximization mode, we provide up to 150% enhancement compared to using only one interface, without any changes to legacy servers.
