ECE Professor Ozan Tonguz delivered the keynote address at the IEEE 2010 Vehicular Networking Conference (VNC), held Dec. 13-15 in Jersey City, NJ. The conference emphasized the research challenges of vehicular ad hoc networks at all layers of the protocol stack, and attracted nearly 100 researchers from academia and companies like Toyota, Honda, BMW, Audi, Intel, Nokia Siemens Networks, and Denso.
Tonguz's talk, "Emerging and Future Applications of Vehicular Networks: A Vision," elaborated on the importance of vehicular networks to sustainable energy (via electric cars), a greener environment, reduced carbon footprint and smart grid. He also discussed the burgeoning role of vehicular ad hoc networks as an important enabler. In particular, the talk described a biologically inspired scheme known as "Virtual Traffic Lights" (co-invented in 2009 by Tonguz, Professor Michel Ferreira at the University of Porto and their students) that illustrates how congestion - a "grand challenge of our times" - can be mitigated by the vehicle-to-vehicle communications capability of modern cars. The biologically inspired new scheme invented by Tonguz and Ferreira can increase traffic flow rates in urban areas by 60 percent during rush hours, which could substantially decrease commute times for workers in urban areas, lessen congestion, reduce the carbon footprint of future cars, support a greener environment and increase productivity.
