@rakesh:
No. of nodes alive at the end of a round is the same as network lifetime.
I didnt use xgraph ... so can't suggest anything.

@nmmn134
I saw the same .. leach was better than leach-c.
I can only assume that this is due to the differences between ns2.35 (which i used) and ns2.1 (which Heinzelman) used ... There are significant differences in the implementation on the wireless channel.

However, the shape of my plots match those in the thesis for leach-c too ... and hence, i assumed my simulation was fine.

@deepa 2111
thx a lotttttttttt i changed the energy.cc and wireless-phy.cc as u said and my nergy is < 200 J
GOD bless u.thx a lot

@deepa 2111
Thanks for your reply.
But i want to calculate remaining energy after each round to plot graph.

I install exidus-pegasis_ns-234-leach.tar of exidus. The result seems reasonable. Leach-c was better than Leach because Leach-c was develop from leach.
the plot.

hi deepa2111
please i want to plot leach.alive leach .data and leach.energy (i'm using gnuplot) but i don't know really how to do that,i tried to use this command (plot "leach.X" 1:3 using lines; by the way X here is data,energy or alive) but the graphs that i got are really so strange and don't match with the theoric results !!! could u please help me and tell me what should i do exactly ??
thx in advance.

i want to know how to get correct .nam file for leach
i added following code in WIRELESS.TCL

set nf [open $opt(rp).nam w]
$ns_ namtrace-all-wireless $nf $opt(x) $opt(y)

but in leach.nam file i am getting following output and its not working or showing simulation in nam(just empty window)

V -t * -v 1.0a5 -a 0
W -t * -x 1000 -y 1000
A -t * -n 1 -p 0 -o 0xffffffff -c 31 -a 1
A -t * -h 1 -m 2147483647 -s 0

please tell how to do correct simulation with correct output in leach.nam file asap.
thanx in advance..

hello every one i am doing some modifications in ns-leach.tcl and i am stuck in how to recover the energy of node to know who has the biggest one so i can chose it like second cluster head plz help me

What and how to modify that...plz describe step by step...

I m stuck on the problem:

"In member function ‘void CMUTrace::format_rca(Packet*, int)’:
trace/cmu-trace.cc:1531: error: ‘A’ was not declared in this scope
trace/cmu-trace.cc:1535: error: ‘R’ was not declared in this scope
trace/cmu-trace.cc:1539: error: ‘D’ was not declared in this scope
make: *** [trace/cmu-trace.o] Error 1"

root@ubuntu:/home/raju/ns-allinone-2.34/ns-2.34#

plz plz help.. how to solv???????????

this is my code to select a vice cluster head among cluster nodes, according to their energy, the cluster head chooses among its member , the node with the highest energy . this is the code

# Set the TDMA schedule and send it to all nodes in the cluster.
set TDMA $clusterNodes_
set Ei 0
set nodeID [$self nodeID]
set element $nodeID

foreach element $TDMA {

set E [[$self getER] query]
puts " energy est $E "
if { $Ei < $E } {
set Ei $E

}
}
set SCH $element
puts " le vice cluster de CH $chID est $SCH "

-->the result (energy nodes of each cluster are equal)

@rakeshpanchiwala

Could you please tell me how did you plot it please.and did you use AWk script or not.
Thank you

@lavender

I have plotted graph in xgraph format. Does not need any awk script.

Could you Tell me how please? and i will be grateful.

@Deepa 2111

please when i run the simulation of leach the output was


At 524.60000000005073:
Total Energy = 199.88864065249675
Total Data = 53086
Total Alive = 4

Simulation complete.
even if in the PhD thesis by Heinzelman the time was more than this could you tell me what is the problem please ?
