About this ebook
Introduction to Network Simulator NS2 is a primer providing materials for NS2 beginners, whether students, professors, or researchers for understanding the architecture of Network Simulator 2 (NS2) and for incorporating simulation modules into NS2. The authors discuss the simulation architecture and the key components of NS2 including simulation-related objects, network objects, packet-related objects, and helper objects.
The NS2 modules included within are nodes, links, SimpleLink objects, packets, agents, and applications. Further, the book covers three helper modules: timers, random number generators, and error models. Also included are chapters on summary of debugging, variable and packet tracing, result compilation, and examples for extending NS2. Two appendices provide the details of scripting language Tcl, OTcl and AWK, as well object oriented programming used extensively in NS2.
Introduction to Network Simulator NS2 can be used by researchers, professionals or graduate students studying telecommunication networks.

The authors have done a good job in "explaining" the online NS2 documentation which has missed to explain the essentials. However, there is still opportunity to extend NS2. The improvements (IMHO) are:
1- What functionalities (feature) are already provided in a given version of NS2.
2- Are the functionalities (features) are modular enough to integrate them in order to create a more sophisticated application.
3 - Is there a way that a developer could judge correctly for his/her needs whetehr to write tcl code (interpreted) vs. C++ (compiled) code, or both? i.e. how to figure the diacotomy between tcl and C++?
4 - Assuming, one needs to write new C++ code, how to "integrate" this code? i.e. NS2 make file is the ultimate document that all C++ (including the headers) codes need to be plugged in. Is it possible to know determine the dependencies between new C++ code and the existing code? Do we plug in the C++ code anywhere in the NS2 make file (I suppose not), etc.
