Support for Popular Traffic Generators (12/2005)

Based on user requests, we have added support for additional traffic generators commonly used such as Iperf already and are working on integrating D-ITG with the ORBIT measurement framework.

This will give users a capability to make use of these tools in addition to our own traffic generator (OTG) which allows CBR, Expoo traffic (TCP or UDP) with controllable offered loads and additional Phy layer measurements

More updates will be coming up soon.

Big Grid (10/2005)

Meet the team (02/2005)

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

The workshop has an entire session dedicated to ORBIT where we will present four papers on various aspects. Refer to the documents section on the main ORBIT website ​http://www.orbit-lab.org/doc/pubs .

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.
