Process description method
Method
OPNET

finite state machine
(graphical spec. only)
both process-style
(coroutine-based) and finite
state machine (textual spec.
only)
Direct (non-scheduled) process interaction
Method
OPNET
OMNeT++
"forced interrupt"
member function call of
other module
OPNET
OMNeT++
only processes within an
existing module
simple modules;
Dynamic module creation
What can be created
connections;
compound modules with
arbitrarily complex,
parameterized topologies
Object-oriented concepts
OPNET
OMNeT++
Language
C
C++
Objects
C API functions operating
on object-like data
structures;
full flexibility of C++:
inheritance, polymorphism
etc;
no support for inheritance*, built-in object-oriented
polymorphism or the like
mechanisms
* The graphical user interface of OPNET (from version 3.0) contains an "inheritance mechanism" for
models. This is no real inheritance in the object-oriented sense because it just means that parameter
values can be changed or fixed down, parameters renamed, merged etc. There is no mention about
changing the behaviour of a module (that is, anything like C++’s virtual functions).
