Project
Objectives:
This collaborative NSF project (involving Rutgers, Columbia, Princeton,
Lucent Bell Labs, Thomson and IBM Research) is focused on the creation of a
large-scale wireless network testbed which will facilitate a broad range of
experimental research on next-generation protocols and application
concepts. The NSF grant also supports a total of nine "experimental
work packages" on new wireless network protocol or software concepts
ranging from ad-hoc mesh networks to media delivery and information security.
Technology
Rationale:
It is recognized that powerful technology and market
trends towards portable computing and communication imply an increasingly
important role for wireless access in the next-generation Internet. At the
same time, new sensor and pervasive computing applications are expected to
drive large-scale deployments of embedded computing devices interconnected
via new types of short-range wireless networks. The speed of technology
innovation in the wireless networking field can be significantly increased
with the development of a flexible, open-access wireless network testbed
that can be shared by experimental researchers across the networking
community.
Technical Approach:
The
ORBIT (Open Access Research Testbed for Next-Generation Wireless Networks)
system is a two-tier laboratory emulator/field trial network testbed
designed to achieve reproducibility of experimentation, while also
supporting evaluation of protocols and applications in real-world settings.
In particular, the laboratory-based wireless network emulator is based on a
large two-dimensional grid of static and mobile 802.11x radio nodes which
can be dynamically interconnected into specified topologies with
reproducible wireless channel models. Once the basic protocol or
application concepts have been validated on the lab emulator platform,
users can migrate their experiments to the field trial network which
provides a configurable mix of both high-speed cellular (3G) and 802.11x
wireless access in a real-world setting. Extensive measurement tools will
be provided to support research evaluation, including both network traffic
and radio link/spectrum usage aspects.
Results to
Date and Future Work Plan:
ORBIT
Radio Node released in 3rd Quarter 2005
The ORBIT radio grid
was first made available to research users on an informal basis in Oct
2005, and since then, has rapidly become a de-facto community resource for
evaluation of emerging wireless network architectures and protocols. There
are currently ~120 registered users who have conducted a total of over 4200
x 1-2 hr experiments on the testbed to date. The ORBIT testbed is also
being used as a proof-of-concept prototyping platform for wireless aspects
of GENI, the future Internet research infrastructure.
