Some of our applications have been developed in Tcl/Tk to ease the adaption for Network Simulator ns-2, composed with a hierarchy of C++ classes and OTcl classes (object tcl). Our Airplug-ns add-on for ns-2 allows to reuse code developed for the road or the emulation into the simulator. Other languages can be used however for developing applications. Here, you will find some tips for developing in Tcl.
