how to integrate the "Resource/Energy" leach class into NS-2.34?

@ nzny,

you can change the distance over which the ADV_CH are transmitted. Thats what I did.
Changing RXTresh wont help as the transmitting node transmits with enough power for all nodes to hear

However, it seemed the changes didnot give any effect to the clusterChoices_.

if anyone has any idea, hope you can share...thank you...

Hi all ! @deepa_2111
When I move leach.tr in directory "home/ns-allinone-2.34/ns-2.34" to other path and then I make command ./test . In leach.err show the following content :

Quote:

couldn't open "/tarik/leach.tr": no such file or directory
while executing
"open $opt(tr) w"
invoked from within
"set tracefd [open $opt(tr) w]"
(file "tcl/ex/wireless.tcl" line 219)

I think this error cause I've changed the directory of leach.tr . But when I move leach.tr to initial position and make ./test command again, the above error still occurs.
please someone*helps*me*about*this*problem ! Thanks !

@ minhntbkhn

you need to run .\leach_test and not .\test

Hello,

I installed leach on ns2.34 under fedora 16 (with the help from this forum)

I run the ./test and with fixings here and there, I got no errors on leach.err
leach.err
INITIALIZE THE LIST xListHead
SORTING LIST ...DONE!

But I got weird results on leach.out
leach.out
At 1.099999999999
Total Energy = 22094.xxxx
Total Data = 0
Total Alive = 4

My "stop" at leach_test is 500 and I tried other value but the results were the same,
it always prints at 1.0999999 with no data

leach.tr also only prints out until 1.10000

any comments, please?

How much is your energy? i mean init_energy in leach_test.

nzny · 11-15-2012, 08:09 PM

@deepa_2111,

thanks for your reply...how do i change the distance over which the ADV_CH are transmitted?

the init_energy is 2
the eq_energy is 1

(what is eq_energy ??? )

I have not do any modification on the code,,

also, can you help me in understanding the output files?
this is my understanding, please tell me if its incorrect,
leach.alive = [time] [node] [0 means dead, 1 means alive]
leach.data = [time] [node] [data sent] --> in my file, the data sent is all zeros
leach.energy = [time] [node] [???]
startup.energy = [time] [node] [???]
leach.save1 = ???
leach.save2 = ???

@deepa_2111,

do you mean that I need to change the max_dist in instproc advertiseClusterHead?

deepa_2111 · 11-16-2012, 09:03 AM

@nzny,

Instead of using the max_dist value, give your own value (I used 86 as this is the max distance over which the energy consumption is proportional to square power of distance). Do not change the max_dist value without verifying how it is used further in the code.

@ forco,

eq_energy means that all nodes are allotted the same amount of energy (init_energy). I think the reason why your code is not printing values could be that all nodes are trying to transmit at the same time, leading to collisions and thereby huge energy expenditure. How many nodes do you have in the network ? If you have 100, max energy can only be 200.

Also, note that increasing no. of nodes to beyond 300 causes the LEACH code to stop working/run improperly.

@forco
leach.alive = [time] [node] [0 means dead, 1 means alive]
leach.data = [time] [node] [all data sent from nodes toward CH and BS]
leach.energy = [time] [node] [energy dissipation of node]
startup.energy = [time] [node] [startup energy]
leach.save1 = I think is a backup file of leach.out!!

Hi all
and @deepa
How can I calculate latency?
time of send data and recieve data is in leach.out
but I need such file like leach.latency
pleas guide me
tnx so much

nzny · 11-16-2012, 06:33 PM

@deepa_2111,

thank you very much for your answer. can we get the received signal strength of the ADV_CH, from wireless-phy.cc may be?

deepa_2111 · 11-17-2012, 10:12 AM

Yes, you can

deepa_2111 · 11-17-2012, 10:14 AM

You can modify the receiver function for the BS (forgot the tcl file name) so that it prints the latency experienced by each CH. This is possible as the BS received packets with the node ID and the time at which the transmission was done by the CH
