Subject: Query about ns-2.30



I am having problem while configuring the underwater sensor network in
ns-2.30. while I run the tcl script it says:

 invalid command name "Mac/UnderwaterMac"
    while executing
"Mac/UnderwaterMac set bit_rate_ 1.0e4"

and when I try to comment this line in the program it shows me this error:

invalid command name "Channel/UnderwaterChannel"
    while executing
"Channel/UnderwaterChannel create _o4 "


 I searched a lot but could not find the reason and solution of these
errors. please help.
