Abstract
In this paper we present MultiNets, a system which is capa- ble of switching between wireless network interfaces on mo- bile devices in real-time. MultiNets is motivated by the need of smartphone platforms to save energy, offload data traffic, and achieve higher throughput. We describe the architecture of MultiNets and demonstrate the methodology to perform switching in Linux based mobile OSes such as Android. Our analysis on mobile data traces collected from real users shows that with real-time switching we can save 27.4% of the energy, offload 79.82% of the data traffic, and achieve 7 times more throughput on average. We deploy MultiNets in a real world scenario and our experimental results show that depending on the user requirements, it outperforms the state- of-the-art Android system either by saving up to 33.75% energy, or achieving near-optimal offloading, or achieving near-optimal throughput while substantially reducing TCP interruptions due to switching.
