Introduction to Network Simulator NS2 is a primer providing materials for NS2beginners, whether students, professors, or researchers for understanding thearchitecture 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 packettracing, 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. Provides a guideline on how to set-up, use, and extend NS2 Presents a layered approach to introduce communication networking protocols and their simulation using NS2. Includes a large number of examples (e.g., codes) on simulationusing NS2. Contains supplementary material (e.g., simulation exercises) for classes and laboratories on telecommunications networking.
