Networked testbeds

Above left: Luiz DaSilva and Ph.D. student Vivek Srivastava configure the network testbed at the ARI, while (above right) Scott Midkiff and Ph.D. students George Hadjichristofi and Tao Lin in Blacksburg observe the current network topology in a test of a mobile ad hoc routing protocol developed by Lin.

The two testbeds are linked via the Internet using a virtual private network to enable collaborative research. The testbeds, developed with support from the Office of Naval Research and the NSF, are used to conduct research in mobile ad hoc networks, including routing algorithms and protocols, network quality of service based on distributed policy-based network management, security architectures for ad hoc systems, and network support for real-time systems.

A unique feature of the testbeds is a special switch that lets researchers emulate a wireless and mobile environment using standard computers and network connections.
