Demo List:

Ethem Sozer, Milica Stojanovic: R-Modem (MIT)

The authors will show their Reconfigurable Modem or the R-Modem.

Iuliu Vasilescu, Carrick Detweiller, Daniela Rus: iV-Modem (MIT)

The authors propose to demonstrate the underwater sensor network hardware they designed, built, and deployed for perception, communications, and control experiments in the ocean. The hardware consists of static sensor network nodes and mobile robots that are dually networked optically (for point-to-point transmission at 300kb/s and acoustically for broadcast communication over hundreds of meters range at 300b/s. The authors will also demonstrate the results collected during experiments with this system in the ocean, in rivers, and in lakes.

Ryan Kastner, Bridget Benson: Acoustic Modem (UCSB)

The authors propose to demo their Mooring Modem prototype in an 18 inch long plastic container filled with water. The demo will consist of one-way communication from the Mooring Modem Transmitter to the Mooring Modem Receiver. The Transmitter will send a training sequence of ones and zeros followed by 30 bytes of time and temperature data (that were gathered from actual sensors on the Santa Barbara CHAnnel Relocatable Mooring or SB CHARM). The Receiver will use the training sequence to locate the start of the valid data and store the 30 bytes of time and temperature data into a buffer. An oscilloscope will be hooked up to receive end to allow viewers to see the received signal. A Matlab script will then be run to compare the transmitted 30 data bytes with the received 30 data bytes to determine the bit error rate.

Gaurav Sukhatme: Robotics/Algae Detector (USC)

In their demo, the authors will introduce their Networked Aquatic Microbial Observing Systems which is designed for marine monitoring. Results from experiments with autonomous boat navigation and navigation improvements will also be included.

Jim Partan: Micro-Modem (WHOI)

Jim Partan from WHOI will demonstrate their Micro-modem. It is a small-footprint low-power acoustic modem.
