Modeling Interface for NS-2

Overview

The process of designing a simulation model requires a very good knowledge of the OTcl interface of ns-2. The script writing process is very long and tedious. Given these difficulties with the use of ns-2, Laboratories of Computer Sciences and Mathematics (LIM) of the University of la Reunion has developed a project for a modeling interface which can be used to easily elaborate a simulation model for ns-2 without a good knowledge of Tcl. This interface aims to lead rapid modelling in the congestion area.

Tool Description

This interface is a tool to develop butterfly-like model and to compute some of commonly used metrics. Morever it can generate graph. It is developped in OTcl with inclusion of unix and awk commands. This interface runs on any ns version as it uses only generic format of ns traces. This interface can be used to:

• create nodes and links,
• define hosts and traffic sources and their acess links,
• compute performance metrics,
• generate trace files, statistics and graphs like thoses below.

The items provided with this tool include:

• typical models (short-lived flows, self-clocking,..),
• library of scripts

Before to use this tool, you must install the latest ns-2 version. See the installation instructions here.

This modelling interface is an open-source project. So the ns-2 community members are invited to use this tool and to contribute to make this tool better. Any remarks can be done at :
