Connected Vehicles:  

Connected Vehicles (CV) refer to vehicles that have connectivity with other vehicles or infrastructure through wireless networks.  According to the US DOT, "Connected vehicles have the potential to transform the way Americans travel through the creation of a safe, inter-operable wireless communications network that includes cars, buses, trucks, trains, traffic signals, cell phones, and other devices. Like the Internet, which provides information connectivity, connected vehicle technology provides a starting point for transportation connectivity that will potentially enable countless applications and spawn new industries. "

The US-DOT's CV architecture included a distributed computing framework involving a new network stack that included a variant of the IEEE 802.11a MAC and PHY layer standard operating over a block of spectrum dedicated to CVs.  However  the US Government is re-thinking aspects of the system, including if the CV spectrum should be accessible by commodity WiFi devices and if the system should be less dependent on specific networking stacks.  Our recent work explores several CV applications such as Queue Warning and Platooning.  We are exploring different system design choices and identifying and solving specific problems that collectively contribute to advances in emerging connected and autonomous vehicle systems and more broadly to advances in emerging application systems involving highly mobile, intelligent devices.
