3)

..... The reply is .....

what changes have you done ????
the error is in the function checkAlive when the application try to remove the node 17 from the interface !!

i installed LEACH manually by making changes in the required files using steps written in NS2 Leach Implementation by Jason A. Pamplin and using mit.tar.gz.

thn i set some global variables like follows

export RCA_LIBRARY=/ns-allinone-2.34/ns-2.34/mit/rca
export uAMPS_LIBRARY=/ns-allinone-2.34/ns-2.34/mit/uAMPS
export PATH=/ns-allinone-2.34/tcl8.4.14/unix
export PATH=/ns-allinone-2.34/tk8.4.14/unix
export PATH=/ns-allinone-2.34/bin
export LD_LIBRARY_PATH=/ns-allinone-2.34/tcl8.4.18/unix
export LD_LIBRARY_PATH=/ns-allinone-2.34/tk8.4.18/unix
export LD_LIBRARY_PATH=/ns-allinone-2.34/otcl-1.13
export LD_LIBRARY_PATH=/ns-allinone-2.34/library
export TCL_LIBRARY=/ns-allinone-2.34/tcl8.4.18/library
export RCA_LIBRARY=/ns-allinone-2.34/ns-2.34/mit/rca

thn i changed dst_ to dst_addr_ in ns_leach.tcl.

now i dont know how can i fix that bug.

hi knudfl and emtarik
any body pls help me. i have searched this on net but couldnt find any help. kindly guide me if any of you has any idea of solving it. emtarik told me the reason of this error but didnt tell me how to resolve it.

Hi,I am a newbie here and glad to see everyone.
the original test file is like this,
#!/bin/bash
cd tcl/ex
ns wireless-demo-csci694.tcl
sleep 2

cd ../../
./leach_test
=======
My question is that why run wireless_demo-.. before leach_test, why do this? thx a lot!

Hello, everyone, I find a mistake that in the leach_test file, x=1000 y=1000, but in the 100nodes.txt file the nodes are all in 100*100. Is this an error? If is, maybe we must modify the genscen file i think. thank you !

can anyone please mail me leach code for ns2.34 as rapidshare links are not working.
Thanks

The "tarik-ns234-leach.tar.bz2" has been sent to you.

Hello, could you help me to answer the questions post #131 and #132, plz!
#131: I cannot understand x=1000, y=1000, but in 100nodes.txt file, all nodes in 100*100
#132: I think to run ns wireless-demo-csci694.tcl is to configure mobile nodes, right?

Thank you very much!
