LEACH Protocol (Mit + uAMPS )

ITengineer · 03-27-2017, 02:31 PM

Hello My friend
Really new in ns2 and I am installing leach protocols (mit-uAMPS) in ns-2.35 and success to run the leach_test and wireless.tcl and get no error and there are leach.tr and leach.out .
My problems are I have my own scenarios which I make it in setdest in ns2
how I can apply this scenario in leach protocol and the change must do in wireless.tcl and leach_test .

Also I need the Packet delivery ratio (PDF) how I can calculate it in leach from leach.tr or leach.out

Thank you

Please read wireless.tcl to know that a scenario file is already used :
Like ../mobility/scene/scen-670x670-50-600-20-0, or scen-670x670-50-600-20-2.
(Line number : $ grep -n mobility wireless.tcl ) (The "cbr" traffic file will also be listed.)

So you can just try adding your own file specs to wireless.tcl, and the file(s) to tcl/mobility

About Packet delivery ratio, PDF :
Find a file.awk in awk#perl#python__scripts-1-2017.tar.gz (~170 scripts) that can work with your file

Thank you very much knudfl to fast answer
I put my scenario in the wireless.tcl and there is no errors
My question is ... there are also scenario in the leach_test file must I change it or not ? also the result for simulation for leach protocols in leach.tr or leach.out ?

Thank you

You can try making copies of 'leach_test' ( 1-leach_test , 2-leach_test ).
... And then try out the modifications : ./1-leach_test , ./2-leach_test

LEACH Resulats
I hope all have a nice day
I installed Mit-uAmps in Ns-2.35 and run leach_test and No error in leach.err My problem When I need to calculate the packet send and packets drop and PDR from leach.tr by using AWK I get different results in each time I run leach_test.
Please, any body can help me for that.

Best Regards

Re #5.

"Different results / random results" :

I guess that's caused by the ns2 function "random seed".
Though seed is set to 0.0, seed is by definition still random, AFAIK.

Using grep with the Leach files :

Code:

$ grep -Rin seed *
common/mobilenode.cc:228:              energy_model()->afe()->set_sleepseed(atof(argv[2]));
mit/uAMPS/ns-bsapp.tcl:30:  $rng_ seed 0
mit/uAMPS/ns-leach.tcl:39:  $rng_ seed 0
mit/uAMPS/ns-mte.tcl:32:  $rng_ seed 0
mit/uAMPS/sims/genscen:11:$rng seed 0
tcl/ex/wireless.tcl:57:set opt(seed)            0.0
tcl/ex/wireless.tcl:116:        puts "\t\t\[-seed seed\] \[-stop sec\] \[-tr tracefile\]\n"
tcl/ex/wireless.tcl:122:        lappend optlist cp nn seed sc stop tr x y
tcl/ex/wireless.tcl:206:if {$opt(seed) > 0} {
tcl/ex/wireless.tcl:207:        puts "Seeding Random number generator with $opt(seed)\n"
tcl/ex/wireless.tcl:208:        ns-random $opt(seed)
tcl/ex/wireless.tcl:304:puts $tracefd "M 0.0 sc $opt(sc) cp $opt(cp) seed $opt(seed)"

The reason for "random seed" : ns2 intends to imitate a real world situation. AFAIK.

Thank you very much knudfl
I will check that

ITengineer · 04-05-2017, 03:08 PM

I want to thanks again knudfl Really I check seed it is 0 in all places, and it is the same problem the result is different when run leach_test and read results from leach.tr please see the attach files maybe u can help me.
thanks knudfl

Sorry, but do you really not understand what a random number is??? It STARTS with 0...and generates a random number. It will NEVER be the same twice.

ITengineer · 04-05-2017, 03:31 PM

Really I understand what you mean But? I want to make comparative and I fix the number of nodes and all parameters and when run Leach_ test and see the results when nodes are 50 and nodes are 100 it's same PDR and packet lsot and etc ... I am new in this field.

Thanks

And you are seeing those results. The 'field' doesn't matter in this context....a random number is just that: RANDOM. You won't get the same results twice. Not sure what you don't understand about that....

ITengineer · 04-06-2017, 04:46 AM

Thanks TB0ne
I want to make comparative and I fix the number of nodes and all parameters. when running leach_test twice the results of PDR, packet lost and etc ...which read it from leach.tr different in each time and I don't change any parameters I thought if I don't change the parameters results must be same . But I get not same when running leach_test
Thanks

To get non-deterministic behavior, set the seed of the default RNG to 0.
This will set the seed based on the current time of day and a counter.

I.e. "seed = 0" causes a random result.

YOU ARE USING A RANDOM NUMBER GENERATOR...IT WILL GENERATE RANDOM NUMBERS. How, exactly do you think you'll get the same results twice with random values???? What do you not understand about this???? The seed is where the random number pool STARTS from.

If you truly can't understand that, then you need to ask your teacher to explain what a random number is.

Thank you very much knudf for your cooperation. I now understand that But I have another question why always receive in zero PLeease if you guide me to solve this problem
