DARPA GloMo PI Meeting 2000


Date July 11th - 13th, 2000
Location Eatontown, New Jersey, USA
Participants Prof. Gary Minden, Prof. Joseph Evans, Prof. Otto Koudelka
Dan DePardo, Artur Leung, Leon Searl, Pooja Wagh


This is the fifth and the last PI meeting for the DARPA Global Mobile Information Systems (GloMo) project. During this conference, technologies for the next generation military mobile wireless information system were demonstrated. The technologies allow mobile users to be automatically linked together via an ad hoc mobile network. Network topology is automatically configured for different scenarios. Voice, data, and video can be shared among users.


The conference took place at Eatontown, New Jersey. It is about 40 miles south of Newark, NJ, and roughly 2.5 miles west of the Pacific coast. The following map from Mapquest and satellite images from USGS show the location of the conference center (click to show a larger image):

ITTC's Achievement

Two key technologies from ITTC were demonstrated during the conference -- the Wireless ATM Emulator and the High-Speed Mobile Modem. The following diagram shows the RDRN network topology in detail.

GloMo 2000 RDRN Network Topology

Wireless ATM Backbone Emulator

The wireless ATM emulator allows RDRN software developer to understand and test various RDRN configurations in a controlled environment. The emulator hardware, which is the blue box shown in the picture (not available yet), contains 12 computers which emluates 12 mobile nodes which are connected wirelessly as an ATM network.
During the conference demonstration, the emulator was configured as the backbone network, carrying traffic for other groups as well as the traffic for the second part of our demo. The network topology shown above clearly shows the emulator's role during the demonstration.

High-Speed Mobile Modem

The mobile modem demonstrated the technology for connecting mobile nodes to the access point via a high-speed wireless link. The link can be configured as 1, 2, or 4Mbps, allowing remote users to communicate with voice, data, audio, etc. Another key feature of the modem is its ability to adapt to different environment by adjusting the data rate, transmit power, transmit/receive channel, antenna sectorization, etc., which leads to more efficient use of resource.
The demonstration was configured with one radio placed outside the conference room and connected to a laptop computer. The other radio was placed on the roof of the conference site and connected to the RDRN wireless ATM emulator via the Alpha TOC hub. The RDRN emulator carried the video conferencing traffic between the two computers (the two laptops with a video logo on top).
