while running leach algorithm in ns2 tcl script i found this error
no such variable
(read trace on "env(uAMPS_LIBRARY)")
invoked from within
"source $env(uAMPS_LIBRARY)/ns-bsapp.tcl"
(file "le.tcl" line 9)
can anyone tell me whats a exactly problem in this and how it is solved..

during installation of ns2 all in one package creates problem
i have ns-allinone-2.35 in home folder but i cant acess it
this problem occur
shruti@shruti-Inspiron-N4010:~$ cd /home/a/ns-allinone-2.35
bash: cd: /home/a/ns-allinone-2.35: No such file or directory
shruti@shruti-Inspiron-N4010:~$
how should i solve it

hi all
I installed ns2 in ubuntu 12.04 and run leach on it without any error(I fixed them)
