ns 2.28 下 SPAN节能协议源码

The way to run the various SPAN/PSM testcases is to CD to: 
.../ns-2.28/tcl/ex
and then run:
run-span.pl tcl/mobility/scene/<scen>.scen

You 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 patterns

alive.pl    - parses packet trace file (.tr) and logs nodes dying

ctr.pl      - parses packet trace file (.tr) and reports loss rate, latency,
              hops, etc

time.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.#.blah

run.pl      - runs a scenario file w/o span and psm; usage: run.pl scenfile;
              generates .tr, .out, and .stdout files in /tmp/scenfile

run-span.pl - similar to run.pl, but uses psm and span

run-psm.pl  - similar to run.pl, uses psm but not span

uptime.pl   - parses packet trace file (.tr) and reports sleep and idle time
              stats

capacity.pl - parses packet trace file (.tr) and reports capacity periodically
