Software:
 * Mobility Satellite Emulation Testbed (MSET),a highly modular emulation
   framework used to study mobility effects (line of sight blockages, beam
   and satellite handovers) in satellite networks. The satellite link
   emulation component was delivered to Lockheed Martin.
 * Black Box Profiler, a traffic generation/measurement system based on ns-2
   simulator, modified Linux network driver, and Click modular router.  The
   system is capable of creating arbitrary traffic flow scenarios with multiple
   unique IPs, as well as measuring packet loss, corruption, and delay with
   microsecond precision.  The tool is planned to be released in early 2008.
 * EMIST Tool Suite: a collection of tools designed to control, measure, and
   analyze experiments on testbeds. The tools can be downloaded at
