Hi everyone,

I have final year project related to the LEACH routing protocol. I want to change the number of nodes for LEACH? As for existing package, it is already 100 nodes, and i want to change it to 80 nodes and below..what should I do?

Thanks

Welcome to LQ.

The files used in the leach simulation :
$ export RCA_LIBRARY=/<name>/ns-allinone-2.34/ns-2.34/mit/rca && export uAMPS_LIBRARY=/home/<name>/ns-allinone-2.34/ns-2.34/mit/uAMPS && ./test

... are : { test, leach_test, tcl/ex/wireless.tcl, mit/uAMPS/sims/nodescen,
mit/uAMPS/sims/100nodes.txt, tcl/mobility/{mte.tcl, stat-clus.tcl} }, etc. etc.

The file `100nodes.txt´ was generated with mit/uAMPS/sims/genscen ,
like $ ns genscen
* Edit a copy of genscen (genscen-50) to 50 nodes , and $ ns genscen-50
... will create the file "new50nodes.txt".

Now edit line 35 in 'leach_test', nn=101 ,,, to : nn=51
.. and line 17, topology_file="mit/uAMPS/sims/100nodes.txt"
..to : topology_file="mit/uAMPS/sims/new50nodes.txt"

Thankz for your response knudfl..

I've already follow your instruction..but the output still showing 100nodes or can be said nothing changes..i dont know what else did i missed..can u share your wireless.tcl file?..it is default wireless.tcl file right?anyway my dimension is 100*100..

this is what appear on my terminal:

num_nodes is set 61
INITIALIZE THE LIST xListHead
*** NOTE: no connection pattern specified.
Loading scenario file...
Load complete...
Starting Simulation...
channel.cc:sendUp - Calc highestAntennaZ_ and distCST_
highestAntennaZ_ = 1.5, distCST_ = 50.5
SORTING LISTS ...DONE!
NS EXITING...

why there is no connection pattern specified?

# 3 .
I used the "leach+pegasis-ns234-files-2.tar.gz" setup. (By @exidus.)
So that's "my wireless.tcl".

Be aware that post #2 doesn't claim to get the result "50 nodes".
It's just some hint's. There may be more files to edit.
Please read all the leach tcl files in mit/ and tcl/mobility/.

The three versions of wireless.tcl I can think of are attached →
a) @MayTamer (classic mit)
b) Leach + pegasis, by @exidus
c) The @deepa_2111 ns-2.35+leach project.

Hi, knudfl and Faez,

I'm also implementing several scenarios with various number of nodes, I've followed what knudfl had suggested in post #2 but I'm wondering where does the result from running the new leach_test exist? Since my leach.out still shows 100 nodes as it usually is.

Thanks mates!
