ns2measure : An Integrated Framework for Enabling Effective Data Collection and Statistical Analysis with ns2


The Network Simulator 2 (ns2) is an open source tool for network simulation. When planning for large-scale simulation experiments, an efficient and flexible data collection and a statistically sound output data analysis are important aspects to keep in mind. Unfortunately, ns2 offers little support for data collection, and statistical analysis of the simulation results is most often performed offline, using either home made code or available packages, which are not integrated with ns2.

In this site, you will find two complementary contributions:

  • the first one consists of a set of C++ modules, that allow a flexible and efficient data collection;
  • the second one is a software framework, which is fully integrated with ns2, which performs all the operations required to carry out simulation experiments in a statistically sound way.

NS WorkBench : Graphical User Interface For Network Simulator


nsBench is a drag-and-drop GUI and easy to use in undergraduate and graduate networking courses. nsBench makes NS-2 simulation development and analysis faster and easier for students and researchers without losing the flexibility or expressiveness gained by writing a script.

nsBench v1.0 features include :

  • Nodes, simplex/duplex links and LANs
  • Agents: TCP, UDP, TCPSink, TCP/Fack, TCP/FullTcp, TCP/Newreno, TCP/Reno, TCP/Sack1, TCPSink, TCPSink/Sack1, TCPSink/DelAck, TCPSink/Sack1/DelAck, TCP/Vegas, Null Agent
  • Applications/Traffic: FTP, Telent, Http/Server, Http/Client, Http/Cache, webtraf, Traffic/CBR, Traffic/Pareto, Traffic/Exponential
  • Services: Multicast, Packet Scheduling, RED, DiffServ
  • Creating "Groups" concept to compensate for "loops"
  • Scenario generator
  • Link Monitors
  • Loss Models
  • Routing Protocols
