Complexity of current computer networks, including eg, local networks, large structured
networks, wireless sensor networks, datacenter backbones, requires a thorough study to …

Network Simulator (Version 2), widely known as NS2, is simply an eventdriven simulation
tool that has proved useful in studying the dynamic nature of communication networks …

As networks of computing devices grow larger and more complex, the need for highly
accurate and scalable network simulation technologies becomes critical. Despite the …

Purpose NS (version 2) is an object-oriented, discrete event driven network simulator
developed at UC Berkely written in C++ and OTcl. NS is primarily useful for simulating local …

Network operators and researchers constantly search for platforms to evaluate future
deployments and test new research ideas. When experimenting, they usually face …

A widespread methodology for performance analysis in the field of communication systems
engineering is network simulation. While ns-2 has established itself as virtually the standard …

In the network research area, it is very costly to deploy a complete test bed containing
multiple networked computers, routers and data links to validate and verify a certain network …

Simulation software is an important platform of finding results to be expected from a practical
hardware setup which is costly and tedious to modify frequently. There are a lot of Network …

In this paper we present a novel framework for ns2 to facilitate the simulation and, in
general, the design of beyond 3G networks. The set of libraries we wrote for this purpose is …

This paper presents a comparative study of two well-known network simulators: OPNET
Modeler and Ns-2. Other studies in this area have generally been confined to just one …
