Cognitive and Cooperative Cars (CCC)

Today’s vehicles are equipped with a plurality of microprocessors and microcontrollers, in some models easily exceeding one hundred.  Adding to this immense processing power, various sensing capabilities, unlimited battery lifetime, and large body for placement of multiple radars and sensors, makes our vehicles very powerful sensing and computing machines. From the three pillars of sensing, computing, and communication—for becoming a cognitive node— our vehicles are well equipped with the former two, but significantly deprived of the third pillar. Despite much progress in manufacturing sophisticated vehicles, the communication methods among drivers on reads are primitive, through visual contact and light signals, which quickly loses its effectiveness in high speeds and in non-line-of-sight. Car accidents and fatalities beget billion dollar losses annually. In police reports and on-scene investigations, human factors are found to be the definite cause for 70% of the crashes. Most of such accidents can be prevented if wireless communication and networking devices are installed in cars that allowed vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication. But, what is the most appropriate communication technology that can be used in cars and also be attractive for future buyers?

The next generation of car buyers is the tweeter and facebook generation. For them, the most attractive feature is not the engine horsepower, rather the capability for onboard social networking and continuous connection to their buddies. Are our roads and vehicles ready for digital dashboards and social networks? What is the technology that can support such applications? Can LTE and Dedicated Short Range Communication (DSRC) technologies coexist? These are some of the questions one might ask when building a cognitive car. In this tutorial, we will review the techniques and the challenges for cooperative communication in cognitive vehicular environment. We will discuss all layers in the communication stack including, applications, Wireless Access in Vehicular Environment (WAVE) short messaging, IEEE1609 and IEEE802.11p suite of standards, security, and resource management. We will also discuss research challenges in the communication and networking including congestion control, topology transparent scheduling, and the application of network coding in vehicular networks.
