Seamless Flow Migration on Smartphones Without Network Support
This paper addresses the following question: Is it possible to migrate TCP/IP flows between different networks on modern mobile devices, without infrastructure support or protocol changes? To answer this question, the authors make three research contributions. They report a comprehensive characterization of IP traffic on smartphones using traces collected from 27 iPhone 3GS users for three months. Driven by the findings from the characterization, they devise two novel system mechanisms for mobile devices to support seamless flow migration without network support, and extensively evaluate their effectiveness using the field collected traces of real-life usage.
