Abstract

   Mobile networks are both poorly understood and difficult to
   experiment with.  This RFC argues that mobile network tracing
   provides both tools to improve our understanding of wireless
   channels, as well as to build realistic, repeatable testbeds for
   mobile software and systems.  The RFC is a status report on our work
   tracing mobile networks.  Our goal is to begin discussion on a
   standard format for mobile network tracing as well as a testbed for
   mobile systems research.  We present our format for collecting mobile
   network traces, and tools to produce from such traces analytical
   models of mobile network behavior.

   We also describe a set of tools to provide network modulation based
   on collected traces.  Modulation allows the emulation of wireless
   channel latency, bandwidth, loss, and error rates on private, wired
   networks.  This allows system designers to test systems in a
   realistic yet repeatable manner.
