RT Conference Proceedings T1 Opportunistic mobility with multipath TCP A1 Raiciu, Costin A1 Nicolescu, Dragos A1 Bagnulo Braun, Marcelo Gabriel A1 Handley, Mark James AB Host mobility has traditionally been solved at the network layer, but even though Mobile IP has been standardised for 15 years, it hasn’t been supported by operators. IP’s double role as a location identif er and communication endpoint identif er brings a number of functional and performance problems. We argue that the best place to handle mobility is at the transport layer. While this is not a new argument, we believe that the emerging standard of Multipath TCP (MPTCP) can be used to solve many issues related to mobility. MPTCP naturally implements make-before-break, can be incrementally deployed, is backwards compatible with standard TCP, and could even ease incremental adoption of IPv6. Using simulations and indoor experiments with WiFi and 3G, we show that MPTCP gives better throughput, achieves smoother handoffs, and can be tuned to lower energy consumption.
