Multipath TCP is a recent TCP extension that enables multihomed hosts like smartphones to send and receive data over multiple interfaces. Despite the growing interest in this new TCP extension, little is known about its behavior with real applications in wireless networks. Our paper "A First Analysis of Multipath TCP on Smartphones" analyzes a trace from a SOCKS proxy serving smartphones using Multipath TCP. This first detailed study of real Multipath TCP smartphone traffic reveals several interesting points about its behavior in the wild.

Dataset of RSSI measurement on the ORBIT testbed.

We performed experiments wherein noise injection was used as a method for mapping real world wireless network topologies onto the ORBIT testbed. This dataset includes received signal strength indicator (RSSI) for each correctly received frame at receiver nodes for different levels of noise injected on the ORBIT testbed.
