WARP Videos

We have created a number of videos which offer both demonstrations of WARP and tutorials on using WARP. This collection will grow with time as we create more WARP videos.

Most of these videos were edited using Apple's Final Cut Studio. To view the source video files (the ".mov" files linked below), you will need Apple's free QuickTime software. All of the embedded videos here use the excellent JW FLV Media Player. To view the embedded videos, you need a recent version of the Adobe Flash Player browser plugin


WARPnet: Wireless Open-Access Research Platform for Networks

WARPnet represents a new undertaking for the Rice University Wireless Open-Access Research Platform (WARP). As experimental networks grow in size, the overhead of managing an experiment on that network grows substantially. WARPnet presents a framework for remote management of an experimental network.

WARPnet Overview

This video presents a brief overview of the WARPnet vision.

WARPnet Demonstration (June 2009)

This video presents an early demonstration of WARPnet hardware and software frameworks. The demo is built using second-generation WARP hardware and is managed by custom WARPnet controllers running on Apple iPhones and laptops.


Demo Videos

These videos demonstrate various aspects of WARP in practice.

This video demonstrates a 2x2 MIMO OFDM link. This link utilizes two WARP FPGA boards, four radio boards, two clock boards and one analog board. The physical layer implements a 2-antenna OFDM transmitter utilizing Alamouti's space-time block code. The 2-antenna receiver uses switching diversity. The MAC layer implements a carrier-sensing, random-access MAC protocol. The source code for all layers is available in the WARP Repository.

RTS/CTS solving the hidden node problem

...

This video demonstrates that a Carrier Sense Multiple Access Collision Avoidance (CSMA/CA) MAC protocol improves performance in a hidden node scenario. Two protocols are compared, a two-way handshake CSMA protocol and a four-way handshake CSMA/CA protocol. The two-way handshake CSMA protocol consists of a DATA-ACK exchange and the four-way handshake CSMA/CA protocol consists of an RTS-CTS-DATA-ACK exchange. The hidden node topology is implemented utilizing three WARP FPGA boards, three radio boards, and three clock boards.
