15-744 Semester Project

Projects should be done in groups of two.

Project Ideas

Project Management

You should strongly consider using either Subversion or CVS to perform source code control for your project and the paper you write describing it. I suggest Subversion.

I also strongly suggest writing your course project report using LaTeX. It is the de-facto tool in which most CS research papers are written. While it has a bit of start up cost, it's much easier to collaboratively write complex research papers using LaTeX than using word.

Writing Papers


The most popular network simulators are ns-2 and Opnet. ns-2 is free, and CSD has some licenses for Opnet.

Testbeds and Emulation


Emulab is a network emulation environment at the University of Utah. It provides racks of machines and programmable switches that can be configured to form mostly-arbitrary network topologies, with controllable delay and loss between nodes. It's a great way to test real programs in repeatable conditions or at scales that you can't get on your own.

Emulab also provides a set of wireless nodes that you can control, located around their building. They also have an experimental mobile robot testbed that could make for fun projects (the robots are designed to move computers and radios around so that you can do repeatable experiments involving mobility).

The RON Testbed

The RON testbed is a 37-node distributed Internet testbed. The nodes are mostly US centric, but some are located around the globe. The machines can be used for network measurements or for evaluating your projects. They're managed through Emulab. The RON testbed is similar to, but smaller than...


PlanetLab is a large-scale, distributed collection of machines that can be used for experiments and measurements. It has about 594 nodes scattered over 282 sites. The machines run something linux-ish that you can login to and run programs, and there exist a variety of utilities for automatically distributing software to the nodes, running programs, and so on.

You must sign up to use a PlanetLab account. Please only sign up if you're going to use the account, since it imposes some management overhead on people not involved with the course.

Wireless Nodes

Dave and some of the other faculty have a handful of various wireless nodes, cards, old laptops, etc., available that you may be able to use for your projects.


Mistlab is a wireless testbed with 60 Mica2/Cricket nodes (sensor boards, much like the motes in moteLab) distributed over the 9th floor in the Stata center at MIT's Computer Science and AI Lab. For access, see their web page and send them an email, and please CC: srini on the mail.
