sample code for wsn

[naveen prabu]

I have pasted sample tcl file and scenario file here...
save scn file as wsn1.scn and tcl file as (say)wsn1.tcl and run tcl file...

try runnin this....if any bugs then let me know...

Dear naveen prabu,

 As per your advise i tried it however it doesn't work and here is the error message it came up with i went to the line it is referring to and realize that there is actually something wrong with it.  Here is the error message:

siu06btk@sie59a:~/Documents$ ns wsn1.tcl
bad option "file": must be add, info, remove, variable, vdelete, or vinfo
    while executing
"trace file for wpan (special handling needed)"
    (file "wsn1.tcl" line 47)


Dear nabeen, hoping to hear from you soon, i would like to thank you very much in advance.

Best regards,

Habeshawit2God

P.S please do not hesitate to drop me an e-mail using my personal e-mail and I would also appreciate it if you can give me reply between today and tomorrow as i have to hand in my project on Thursday 19thMarch 2009!!

Hi,

You should inspect the source file and clean it up for line breaks where it
should not be. It is easy, jusr 2-3 places. Split into separate wsn1.scn
file where that information is given. When done, the code works perfectly.

Hi All,

I want to use "802_15_4" in my simulation what should I install to take into consideration??
Thank you in advance.
