Current software

I support open source software by developing and contributing some of my professional and spare time.

Older software

HTTP traffic generator (62K) for the ns-2 network simulator.

STP (Satellite Transport Protocol) UNIX implementation and simulation scripts.

TCP with Selective Acknowledgments for BSD/OS 3.0 .

Here is a collection of perl scripts used to plot the output of LEO satellite simulations in the ns simulator. I have integrated my LEO satellite simulation code with the ns simulator (documentation and code can be found at the ns web site).
UPDATE: Lloyd Wood has enhanced these scripts significantly. Look here.
