Title : Modeling Service Mixes in Access Links

Speaker : Marco Ajmone Marsan, IMDEA Networks Institute, Spain

Access links, both wired and wireless, carry the traffic generated by a mix of services, such as video, voice, web, gaming, etc. Some services generate traffic with constant or almost constant data rate (for example a voice conversation or the live streaming of a sport event) while other services can adapt their data rate to the available network resources (for example a file transfer or a web page download).

The prediction of the performance that can be obtained in presence of mixes of traffic of different nature is important for the definition of access control and scheduling algorithms, and has ben tackled by several researchers, mostly resorting to approximations, because exact solutions are not available.

This talk shows that a simple quasi-optimal admission control scheme allows the simple derivation of exact results that highlight interesting unexpected behaviours.

Title : Joint Communication and Radar Sensing in mmWave Band for Automotive Applications and Beyond

Speaker : Eylem Ekici, The Ohio State University, Columbus

The need for communication for advanced transportation systems was first recognized almost three decades ago. Although a multitude of communication solutions were proposed, standardized, and spectrum allocation done, the deployment of these solutions proved to be much slower than anticipated. In the meantime, while more advanced automotive applications requiring higher communication rates were developed, some of the sub-6GHz bands were deallocated. Although CV2X solutions partially addresses the looming spectrum crunch for automotive applications, the raw bandwidth is insufficient to meet the needs of these emerging applications at the expected scale.

On the other hand, the 76-81GHz range has already been allocated for automotive radar operation. This range is highly underutilized and presents an opportunity to host high data rate communication among vehicles. However, there are a number of challenges to overcome, ranging from implications of mobility to signal processing and resource optimization. In this talk, we will discuss theoretical foundations that allow the radar-communication coexistence in the same band, challenges to be overcome to enable this coexistence, and a number of solutions that lead to practical implementations. These solutions are also expected to have far-reaching implications for other frequency bands to relieve the spectrum crunch that is being felt in the sub-6GHz range.

Title : Data security and privacy in emerging scenarios

Speaker : Pierangela Samarati, Università degli Studi di Milano, Italy

The rapid advancements in Information and Communication Technologies (ICTs) have been greatly changing our society, with clear societal and economic benefits. Mobile technology, Cloud, Big Data, Internet of things, services and technologies that are becoming more and more pervasive and conveniently accessible, towards the realization of a smart society. At the heart of this evolution is the ability to collect, analyze, process and share an ever-increasing amount of data, to extract knowledge for offering personalized and advanced services. A major concern, and potential obstacle, towards the full realization of such evolution is represented by security and privacy issues. I will illustrate some security and privacy issues arising in emerging scenarios, focusing on the problem of managing data while guaranteeing protection of data stored or processed by external providers.
