Age of Mythology

We did some experiments measuring the effects of latency on user performance in Age of Mythology. You can download the maps we used as well as some network traces.

Battery Power

We wrote some software that can measure the battery drain rate on a laptop PC. You can download the Visual C++ source code (with executable already made) here:


Command and Conquer: Generals

We did some experiments measuring the effects of latency on user performance in Command and Conquer: Generals. You can download some network traces here.

CStream - Collaborative Streaming

CStream (Collaborative Streaming) is a system that aggregates bandwidth from multiple cooperating users in a neighborhood. When a user streams a video, CStream aggregates bandwidth by connecting to nearby cooperating users and use their Internet connection in addition to the user's own connection.

CUBIC for ns-3

An implementation of CUBIC in ns-3, designed based on the current literature describing the CUBIC algorithm and an examination of source code in the Linux kernel. TCP CUBIC, the default TCP congestion control algorithm in the Linux kernel and, given the popularity of Linux servers, one of the most widely used variants of TCP in use.

(Earlier versions can be found here.)

Used in:


Dynamic Class Based Thresholds (D-CBT)

D-CBT is an router queue management mechanism that extends RED by having three classes of traffic: TCP, UDP and tagged UDP (multimedia). It provides fairness among the classes of flows using dynamic thresholds for each class.

Goddard Streaming Media System

We have design and implemente a streaming system (client and server) called Goddard for use in the NS simulator. Goddard is designed based on the behaviors of Real Networks streaming media and Windows Stream media, as observed in measurements studies from work at the Video Tracer project page.

Used in:

(Note, the system is named after Robert Goddard, the "Father of Modern Rocketry", and a WPI alumnus.)


Implicit Interest Indicators

Some of the research in our REFER group is looking at the correlation between user Web browsing actions (implicit interest) with explicit interest. We built a Web browser (called Curious Browser) that records scrolling, access time, mouse movement and mouse clicks, conducted user tests with a bunch of volunteers, and analyzed the gathered data. The Curious Browser and the dataset collected is available below.

Madden Online NFL Football

We studied the effects of latency on Madden Football. We also captured some network traces, which you can look at here.

Used in:


MM-Flow

MM-Flow is a set of rate-based applications for NS that use AIMD congestion control built on top of UDP. They are designed for better-performing yet responsive multimedia applications. We've implemented them in NS. Note, these are included with the ns-2 tree if you download D-CBT above.

Used in:


MPEG Movies

Each movie clip was recorded from a VCR using a Video ATI All-in-one capture card into AVI format then converted into MPEG-1. Each clip is about 60 seconds long and 10 MBytes in size.

Used in:


MPFS Benchmark

The benchmark source code here can be used to evaluate the performance of MPFS file systems.

Used in:


NISTNet DropTail

By default the NISTNet emulator manages the router queue by dropping packets using the DRD algorithm. We implemented a simple drop tail implementation, modifying the kernel/knistnet.c source code file. You can download the source code below and read about compilation and installation on the NIST Net page, as they remain the same.


OnLive

We measured the turbulence (size and distribution of network packets) for the OnLive thin client game system for 3 games. We compared them to 2-person Skype video and Youtube. Traces can be found here.

Used in:


QFind

The results data we obtained (minus the ping distributions) from our QFind measurements are available here.

Used in:


Starcraft and Counter-strike

Network games are becoming increasingly popular, but their traffic patterns have received little attention from the academic research community. We have examined network traffic from Counter-Strike and Starcraft thus far. The Commview traces and a parsing tool are available here.

Receiver Based Auto Rate (RBAR)

Receiver Based Auto Rate (RBAR), proposed by Holland et al. in "A Rate-adaptive MAC Protocol for Multi-hop Wireless Networks" (Proceedings of Mobile Computing and Networking, 2001), uses analysis of RTS frames to measure channel quality. RBAR receivers determine the highest feasible frame transmission rate that channel conditions can tolerate and notify the sender of the chosen rate via the CTS frame. Since RTS/CTS messages are sent to the AP, all wireless nodes become aware of the new transmission rate and set their backoff timers accordingly.

Unfortunately, this algorithm is not integrated into ns-2 releases. However, an RBAR simulation module for ns-2 2.1b7 is downloadable from the Rice Networks Group. We re-implemented RBAR in NS 2.27 and extended the physical layer parameters using the specifications of the Lucent OriNOCO wireless PC card. Our implementation can be found here with documentation.

By default, ns-2 provides a two-way ground propagation module. To more accurately simulate physical condition effects on RCAs, an additional ns-2 extension module was implemented that models Ricean (or Rayleigh) fading (Punnoose et al. in Proceedings Vehicular Technology Conference, 2000).


Selective Flooding Simulator

Selective Flooding is a QoS routing algorithm checks the state of the links on a set of pre-computed routes from the source to the destination in parallel and based on this information computes the best route and then reserves resources. We implemented Selective Flooding by extending a QoS routing simulator. That simulator is available here:

Used in:


SRP - A Selective Retransmission Protocol

Selective Retransmission Protocol (SRP) balances the potentially high loss found in UDP with the potentially high latency found in TCP. SRP uses an application-specific decision algorithm (based on an audioconference in this implementation) to determine whether or not to ask for a retransmission for a lost packet, adjusting the loss and latency to the optimum level for the application.

Linux version:

Stats

Stats is designed to be a quick, simple to use program as a Unix filter to generate the summary statistics.


UDP Tools

UDP Ping, UDP Heartbeat and UDP Load are customized ping tools using application-layer UDP packets to provide delay, loss and throughput information. UDP Ping reports round-trip time information while UDP Heartbeat reports one-way link information. UDP Load provides throughput information. Both require applications to be run on the end-hosts.

Unreal Tournament 2003

In studying FPS games under network degrdataions, we've looked at UT2003. We ran multiple full-length games with one player matched against two bots on a small standard map (DM-GAEL) with four different conditions of packet loss and latency. For each game, we captured all network packets for 120 seconds during the middle of the 5 minute match. You can get the tcpdump traces here:

WBest is a wireless bandwidth estimation tool designed for applications that requires fast convergence time and low intrusiveness, such as multimedia streaming applications. WBest employs packet dispersion techniques to provide capacity and available bandwidth information for the underlying wireless networks.
