Islam,

This error is due to a missing superclass declaration; try adding the 
following line above your instproc definition:

Class Agent/IMultiHop -superclass Agent

Here is some OTcl documentation on this:
http://bmrc.berkeley.edu/research/cmt/cmtdoc/otcl/class.html

However, the ns-manual doesn't seem to document this statement at the 
moment.
