Research Methodology


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:





Core Radio/PHY Technology

Radio Resource Management

Mobile Networks and Protocols

Mobile Computing & Security


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 the future mobile Internet, hybrid 4G/WiFi networks, ad hoc and mesh networks, RFID/sensor applications, pervasive/cloud mobile services and vehicular networks

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 be illustrated through the example of the FIA MobilityFirst architecture project which integrates contributions of several research threads at WINLAB including dynamic spectrum access, network MIMO, ad hoc and mesh network protocols, wireless network security & privacy, mobile content delivery, location-aware computing and pervasive context-aware applications. The project also draws on prototype systems built at WINLAB over the years including the Infostations prototype (1999), the ORBIT radio grid (2005), the CNF (cache-and-forward) network architecture (2008), and the GENI open campus network (2010).




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 "network-centric" cognitive radio hardware platform has also been developed

Orbit "Radio Grid" Testbed
The 400-node ORBIT radio grid testbed has been operational at WINLAB since 2005.  The testbed provides experimenters with a flexible platform for conducting a wide range of reproducible wireless networking experiments, and has led to ~100's of published papers.  For more information on ORBIT resources and account setup, see ORBIT portal

Rechargeable Networks
A new project aimed at understanding protocol design and algorithms for energy efficient operation of wireless networks with rechargeable elements. 


Location-Aware Protocols and Network Architecture: This project develops protocols that exploit available location information (usually from GPS) to enhance multi-hop communication and integration with the future Internet infrastructure in highly mobile networks.

Visual MIMO: This project is aimed at developing optical vehicle-to-vehicle (V2V) technology to supplement radio communications in dense environments.  The technical approach is based on a combination of MIMO-inspired multipath processing applied to optical LED arrays and camera detectors. 

MobiityFirst Future Internet Architecture: This is a large NSF-funded collaborative project involving Rutgers, UMass, MIT, UNC, UMich, Duke, U Wisconsin and U Nebraska, with the goal of developing a comprehensive mobility centric future Internet archtiecture.  See project webiste for further details.
