I am trying to find a leach protocol implementation for ns2.34 but all links available are dealing with ns2.27
Are the instructions valid for ns2.34???

Welcome to LQ.

Leach for ns-2.34, files and instructions, post # 5 here :
http://www.linuxquestions.org/questi...2-34-a-870368/

Extra links for the above, post # 28 :

Thank you. I installed Leach...but in leach.out I get many warnings. Moreover results are odd. If 2J per node was initial condition how can 350 J be result energy.

I think there is a debate about the "energy" in one or two of the very long leach threads.
See post #2 for the 'Search link'.

#94 #95 http://www.linuxquestions.org/questi...368/page7.html
etc. #98 , etc.

Content like this is a great change of pace for me. I feel fervently about this and I like learning about this subject

Hello all! I was working with Leach protocol. Can anyone tell me as to why 5% would be the most optimal value. Is there any mathematical derivation possible? Also the group G would mean all nodes that have not become cluster heads in the last (1/p) rounds. Why 20 rounds? Why would these 2 be related?

Pushpita,

Please fo through the Phd Thesis on LEACH by W. Heizelmann. Its's clearly mentioned there why 20sec is chosen as each round.

Adter many simulations, 5% was found to be the optimal value. Forgot which paper had that, but has come across it an year ago. If I find the paper, shall post a link.

Regards,
Deepa

I found the paper. Its the journal paper which has the details.

oh ok .. Can you post the link here ?
Do you mean the LEACH journal paper ?

I had simulation results with the 5% in some other paper.
The same paper talked about LEACH giving 8 times the performance gain over direct transmission

Hi everyone

could anyone give me the step by step instructions (just like ns2.27 given by knudfl and other) about how to install the ns2.34 on ubuntu 10.10 and the instructions about how to install leach on ns2.34 for the ubuntu 10.10?

Thanks in advance...

Ubuntu 10.10 : sudo apt-get install g++-4.1
cd ns-allinone-2.34/ && export CC=gcc-4.1 CXX=g++-4.1 && ./install

Or use "g++41-compat" http://www.linuxquestions.org/questi...asim-932264/#6
cd ns-allinone-2.34/ && export CC=gcc41 CXX=g++41 && ./install


And : Welcome to LQ. .. ..

@knudfl: Thanks for your response and sorry for my duplicate post

I did what you told me to do..

use "g++41-compat" http://www.linuxquestions.org/questi...asim-932264/#6

cd ns-allinone-2.34/ && export CC=gcc41 CXX=g++41 && reboot && ./install

after ./install i found 1 error

-----------------------------
make: *** [tk3d.o] Error 1
tk8.4.18 make failed! Exiting ...
For problems with Tcl/Tk see http://www.scriptics.com
-----------------------------------------
Why is that error occurring and how can i resolve this?

# 12

You'd probably forgotten one or more build requisites :

sudo apt-get install g++ make autoconf automake libtool \
libx11-dev libxmu-dev libxmu-headers libxt-dev

@knudfl: Thank you..now the error is like that..
-------------------------------------------------

----------------------------------------------
How can i resolve this?

# 14.

Either start from scratch with a new unpacked ns-allinone-2.34.tar.gz.

Or : cd ns-allinone-2.34/tcl8.4.18/unix/ && make clean &&
cd ../../tk8.4.18/unix/ && make clean && cd ../../otcl-1.13/ && make clean

Also : Make sure that any Makefile present in the three above gets deleted,
after you have done 'make clean'.
( Not all 'make clean' will remove the Makefile ).
