1.Read chapter 9 and 11 of http://www.isi.edu/nsnam/ns/tutorial.
2.You can find more examples at ns-allinone-2.29/ns-2.29/tcl/ex.
3.For generating random node movements you have to use “setdest” executable 
file. For specifying mobility you have to give  -M<mobilityvalue(m/sec)> as 
argument to “setdest”.
4.For creating random src/dest pair connections you have to use cbrgen.tcl. 
You may find more information regarding these in Marc Greis tutorial.
(Use tcp connections)
5.So first you have to copy setdest and cbrgen.tcl files into your directory 
and then use them.
6.Check files generated by node movement generator "setdest" and traffic 
-scenario generator "cbrgen.tcl" before proceeding.
7.For AODV Broadcasting, use “ns” executable.
8.For AODV Expanding Ring Seach, you have to do two cases
        a)  INITIAL-TTL =2
             INCREMENT=1                for this use “ ns27” executable
             THRESHOLD=7   
     
        b)  INITIAL-TTL =5
             INCREMENT=2               for this use “ ns57” executable
             THRESHOLD=7 
9.Your simulatios may take more memory you may be exceeding your quota.
So,create all trace files in /tmp .
10.Submit your node movement files and traffic scenario files, TCL files, 
perl scripts and termpaper.
