@ Aska123 (#648),
I wrote awk scripts to extract the data required. Then, I imported the generated data to excel and did my calculations.
So, what you need to extract is the time at which the CH sends the data, and time at which the BS receives it. The values are present in the leach.out file.

@eng_mohamed_sc (#632),

If by "original Leach", you mean the version by Heizelman et al (on ns2.1b), the code is definitely not going to work.
It was for an ns2 version which is now obsolete. Obsolete because that ns2 version can no longer be run on today's OS.
Their work was done in 1999, so you'll have to use the OS that was in use then to install ns2.1b.

hello deepa, glad to see u back here..thanx for your reply..please tell me what is the problem in my post #658.Not a single cluster is forming, all nodes are dead n hence total sent data is also showing 0.and also tell how total energy is only 3.29? please help.

@deepa 2111

Hello

I have successfully installed leach on ns2.34
I have no error in leach.err file
I have output in leach.out and leach.tr file.

Please suggest how to plot graph for leach output.
I have installed both gnuplot and xgraph on my system.

I do not know how to select columns from out file.
I also tried Tracegraph software, but it is not loading trace file.

please help.

I want to measure energy of nodes in network

Thanks

Thanks a lot deepa ji.

Happy to see you here.

I do not know how to write awk.
First i have to learn awk.
can you provide some awk script so that i can learn how to write them specific to leach protocol.



Thanks

i have changed path in uAMPS.tcl also.
try to find location of file which is missing and copy file from there and paste in dirctory in which it is showing missing.

You need to make changes to the recv functions (tcl functions) so that a CH can hear ADV from other CHs.
for my thesis, I chose to implement an improved version of EECH to implement a multi hop network, and hence modified the code accordingly.
It is not very difficult to do so.

Like TB0ne says, we cannot write the entire code, and the exercise is pointless if you cannot implement your ideas.

So, to answer ur question, at cluster formation phase, each CH also needs to receive ADV from other CHS, and you need to determine an algorithm to choose which your next hop CH is to be.
hi deepa_2111, i want to implement multi-hop routing on communication between CH node and non-CH nodes, multi-hop only used when non-CH nodes send their data to CH. CH send data to BS using single-hop.
can you give me hint how to make it works?

@ mhmmahdi,

I don't understand ... why would you want to implement multi-hop routing on communication between CH node and non-CH nodes ?
non-CH nodes are within line of sight distance with the CH, so why use multi-hop ? It's a waste of energy to use multi-hop in a direct line of sight communication situation.

Awk is very easy, and I suggest you learn it as it's gonna help you a lot more in future applications.
You can find really good tutorials on the internet.
It is not specific to leach protocol. You can use awk to do whatever you wish.

@ Aska123,

I haven't used gnuplot or xgraph.
Initially, what I did was to use excel to get the values of energy etc after every 10 sec. You can use textpad etc to seach and select all values in a leach.out.
After that, I realised awk scripts are a better way to extract the energy, data packets received and no. of nodes alive after every 10 sec. A single coomand in awk should do the trick for you.
Please learn awk.

yes, i agree with you. but i don't know, my prof. asked me to analyse that.
he said multi-hop will be useful in a big size network.. still need to prove his opinion right or wrong.
thanks for your answer anyway

@mhmdmahdi, hey i tried as u said..but it gives error as ns-pegasis:command not found.I hav checked for ns-pegasis execution file in ns2.34 folder but it is absent.i think the error is due to it only.i have installed exidus-pegasis-leach-ns234-patch.2 not the your package i.e. pegasis-ns-2.34-ubuntu10_i386.deb. Is it for leach protocol? and is it give correct output of leach protocol..if yes..please provide that package here and also tell me steps to install it..please i have spent lots of days to get correct output but still facing problems..please help..
