Recently ns2web had suffered some downtime. However, it is up and running once again. Any inconvenience caused is regretted. If you are working with NS-2, you may try out the remote simulation and online analysis feature of ns2web . Also, read the article in IEEE Wireless Communications magazine on ns2web.

In my previous articles, I have discussed about the Virtual Labs and IEEE WCM Feature Article on ns2web . Today, I would briefly discuss about ns2web with specific focus on one of its more general features -- data plotting utility. Ns2web is the core component of the Advanced Network Technology Virtual Labs. At a high level it has two basic jobs to perform: Execute the NS-2 simulations in a remote server based on the user input code. Help users perform different types of post-simulation analysis using the trace file generated. As such, ns2web itself becomes a sort of mini-project :) Currently, ns2web and the version of it used with the ANT VLab differ on a few minor aspects. The former offers a ``guided scenario generator'' to the users, and an option to export the graphs as external images. However, ns2web is not only for performing network simulations! The software provides a useful feature that might interest you if you want to quickly plot some nice line plots...

The article " A Web-Based Integrated Environment for Simulation and Analysis with NS-2 " appeared as a "Feature Article" in the August 2013 issue of the IEEE Wireless Communications Magazine ( archived URL ). The article presented the design and implementation of a Web-based environment to enable remote network simulations using NS-2, and subsequent analysis using the trace file generated. Plots obtained from the simulation results (as well as, their corresponding data) can be exported as EPS/PDF/PNG files, which helps in using them with research articles.
