Hi, I have the same problem.
ns: _o1130 send_now 0xffffffff 1 46 16 139.0 1: wrong # args: should be "_o1130 self class proc mac_dst link_dst type msg data_size dist code"
(Application/LEACH send_now line 1)
invoked from within
"_o1130 send_now 0xffffffff 1 46 16 139.0 1"
I wonder if your leach has worked or not, if it worked, what did you do to fix it? I have modified my wireless.tcl and leach_test by adding -cp as the URL above said, but it still cannot work. Would someone help?
