64 node sandbox sb9 decommissioned

Sandbox9 (the original 64 node grid) has been decommissioned. The prototype grid served us well and allowed us to design scalable software and infrastructure that aided in the design of the 400 node grid.

Current experimenters scheduled on sb9 are requested to use the bigger grid for the same

March 2006: Recent MIT Technology Review

Recent report from the MIT Technology Review (March/April 2006) on ORBIT. Check ​here

New Building (07/2005)

We moved into our new facilities at 671 Rt. 1 South in New Brunswick.

Meet the team (02/2005)

Ivan Seskar, Prof. Roy Yates, and Prof. Max Ott demonstrated the use of the ORBIT testbed for wireless experimentation at the Tridentcom 2005 conference for testbeds in Trento, Italy from 23th to 25th February. ​http://www.tridentcom.org/techprog.html

The workshop had an entire session dedicated to ORBIT where we presented four papers on various aspects. Refer to the documents section on the main ORBIT website.

Stress Testing of software components (01/2005)

The software team is currently stress-testing the various software components including measurement collection framework, traffic generator, and node imaging software for future release. We have also extended our Beta testers to include users which primarily access the testbed remotely.

Additional radio capabilities (12/2004)

In order to provide heterogeneous environments, we are testing Intel 802.11 a/b/g cards and will deploy them on 32 out of the 64 nodes.

Interference injection for arbitrary topology formation (10/2004)

The ORBIT testbed now supports interference injecting antennas that are connected to an Agilent Raw Waveform Generator. AWGN noise of various power levels can be injected into the grid so as to emulate greater distances between transmitter and receiver and create multi-hop topologies. Interference injection has been used in some experiments and we have been observing up to three hops using a AODV routing protocol.

Mobility Emulation capability (09/2004)

This feature enables experiments that involve mobile nodes. We emulate mobility by spatial switching in software over an array of 128 spatially distributed radio antennas. To emulate mobile nodes, the system selects a sending radio and a receiving radio from the grid that best represents the positions of the mobile nodes as given by the mobility scenario, while the application itself remains running on a node off the grid.

Orbit on TV (01/2004)

ORBIT was highlighted on ​New Jersey Public Television and Radio. Take a look at the NJN News Spot (Follow the link, and look for minute 13:50 on Wednesday 1/21/2004).

Orbit (12/2003)

Rutgers University recently announced the launch of ORBIT in the following ​press release.
