WINLAB has a multidisciplinary, systems-oriented approach to
research that reflects the broad scope and technical challenges of
the Mobile Internet.
WINLAB's core research is organized into four broad areas:
- Radio/PHY
- Radio Resource Management
- Mobile Networks and Protocols
- Mobile Computing
In combination, these broad areas cover the full range of issues that
emerge in creating the Mobile Internet, from propagation and radio
design, to protocols and networking, to the applications that will
drive widespread use and economic growth. By working together and with
sponsors, WINLAB researchers are able to identify those key problems
that will most influence the future of the Wireless Internet, and to
shape a "common systems view" of potential solutions. Emerging wireless
systems under consideration include concepts for "4G", ad-hoc mesh
networks of 802.11 radios, cognitive radio systems and sensor networks
for pervasive applications.
This common systems view leads to research activities that may fall
into any, or all, of the four research areas. These activities may
be carried out by individual professors and students or organized
into larger Focus Projects, which
represent major goal-oriented activities carried out over a specific
period. Research methodology includes a combination of system architecture/design
work, analytical modeling, simulation and experimental proof-of-concept
prototyping.
This process can best be illustrated through the example of INFOSTATIONS,
a wireless system architecture created at WINLAB to solve certain
key problems that face the mobile Internet, and which has in turn
led to a variety of WINLAB research problems and projects.

New:
Spectrum Management and Cognitive Radio
A
theory and system prototyping project aimed at techniques for
significantly improving spectral efficiency in unlicensed bands. Topics
under study include reactive frequency/power control algorithms
and channel etiquette protocols which permit coexistence of multiple
radio technologies. A new "network-centric" cognitive radio hardware
platform project started with NSF support in Fall 2004.
Orbit "Radio Grid" Testbed
A radio grid emulator
with 64 nodes has been set up at WINLAB for the purpose of enabling
reproducible experimental evaluation of emerging wireless network
protocols. A 400-node version is slated for release in October 2005.
MIMO Networks
A
joint theory project (with Princeton and NJIT) aimed at investigating
networking and radio resource management issues which arise in networks
of MIMO radios.
Pervasive Wireless Systems
A new project aimed at understanding network protocols, security methods and software models for
emerging pervasive systems and sensor networks.
