Towards the Tactile Internet – Low Latency Communications in Connected Cars
Abstract—In this talk, we discuss the challenges and opportunities of the Tactile Internet concepts. In particular, we will focus on the connected cars vision in relation to some of the most needed components in modern smart cities: improved road traffic safety combined with reduced travel times and emissions. Using selected application examples such as cooperative adaptive cruise control (or platooning), we assess the needs on the underlying system components with a particular focus on inter-vehicle communication. With the standardization of the DSRC/WAVE protocol stack, the vehicular networking community converged to a common understanding of data dissemination schemes that already have high potentials for many applications. Yet, vehicular networks are way more dynamic than originally considered. Radio signal fading and shadowing effects need to be considered in the entire design process as well as the strong need for low-latency communication, fairness, and robustness. We bring all these aspects together outlining necessary ingredients for future connected cars applications.

Challenges and Solutions for Millimeter-Wave Wireless Networks
Abstract—One of the most promising options to significantly increase data rates in future wireless networks is to vastly increase the communication bandwidth. Such very high bandwidth channels are only available in the extremely high frequency part of the radio spectrum, the millimeter wave band (mm-wave). Upcoming communication technologies, for example IEEE 802.11ad, are already starting to exploit this part of the radio spectrum to achieve data rates of several GBit/s. mm-wave communication is also discussed as key technology for 5G mobile networks. However, communication at such high frequencies also suffers from high attenuation and signal absorption, often restricting communication to line-of-sight scenarios and requiring the use of highly directional antennas. This in turn requires a radical rethinking of wireless network design. On the one hand side, such channels experience little interference, allowing for a high degree of spatial reuse and potentially simpler MAC and interference management mechanisms. On the other hand, such an environment is extremely dynamic and channels may appear and disappear over very short time intervals, in particular for mobile devices. It is essential to take these characteristics into account to design efficient wireless architectures. The talk will highlight main challenges and possible solutions for networking in the mm-wave band.

He is senior member of IEEE and ACM.
Internet of Vehicles: Privacy and Security issues
Abstract—In the Intelligent Vehicle Grid, the car plays the role of a formidable sensor platform, absorbing information from the environment, from other cars (and from the driver) and feeding it to other cars and infrastructure to assist in safe navigation, pollution control, traffic management, etc. The next step in this evolution is the Internet of Autonomous Vehicles. Pioneered by the Google car and supported by several automakers the Internet of Vehicles (IOV) will be a distributed transport fabric capable to make its own decisions about driving customers to their destinations.
Like other important instantiations of the Internet of Things (e.g., the smart building), communications will be essential for the Internet of Vehicles. The vehicles will upload to the Internet a lot of data vital for the Transport System efficiency. They will also communicate with each other to manage time critical tasks like navigation safety and short term traffic congestion mitigation. Unfortunately, when vehicles communicate, they are exposed to privacy intrusion and security attacks. Due to recent events, the automotive industry has become acutely aware of these problems and is struggling to control them. This talk will elaborate on privacy risks and security attacks in autonomous vehicles, and will outline methods to overcome them.
Dr. Mario Gerla is a Professor in the Computer Science Dept at UCLA. He holds an Engineering degree from Politecnico di Milano, Italy and the Ph.D. degree from UCLA.
