The way to run the various SPAN/PSM testcases is to CD to: .../ns-2.28/tcl/exand then run:run-span.pl tcl/mobility/scene/<scen>.scenYou might want to add a "-stop 120" to avoid the simulation from taking too long.  That will generate the appropriate files in /tmp directory,from which you can use some of the output-parsing scripts below.mkscen.pl   - creates scenario files; scenario files contain communication              patterns and movement patternsalive.pl    - parses packet trace file (.tr) and logs nodes dyingctr.pl      - parses packet trace file (.tr) and reports loss rate, latency,              hops, etctime.pl     - parses stderr outputs (.out) and reports power consumption,              coordinator election stats, etc. you will need to change some	      of the settings at the top of the time.pl file. for example, you	      will want to skip nodes in your scen file that are senders and	      receivers, stop accumulating stats after certain number of	      seconds, etc.parse_output.pl (calls parse_dump.pl)            - generate topology pictures for every dump period; usage:	         		 parse_output.pl token < .out file              	      creates token.0.*, token.1.*, etc, where the number is the	      dump period; can plot current topology using gnuplot. for	      example, to plot topology at dump period 0	         load "token.0.core"	      there are other useful files that parse_output.pl generates, in	      the form of token.#.blahrun.pl      - runs a scenario file w/o span and psm; usage: run.pl scenfile;              generates .tr, .out, and .stdout files in /tmp/scenfilerun-span.pl - similar to run.pl, but uses psm and spanrun-psm.pl  - similar to run.pl, uses psm but not spanuptime.pl   - parses packet trace file (.tr) and reports sleep and idle time              statscapacity.pl - parses packet trace file (.tr) and reports capacity periodically
