Platooning is one of the most relevant Vehicle-to-Everything (V2X) services which has attracted attention of both academia and industry. High-density platooning has the potential to reduce fuel consumption due to the reduced air drag and to increase the capacity of the roads due to the smoother traffic flow. The aim of this demo is to illustrate the benefits of Vehicle-to-Vehicle (V2V) communication for high-density car platooning. For this purpose, the demo compares Adaptive Cruise Control (ACC), which relies on on-board sensors only, and Cooperative Adaptive Cruise Control (CACC), which relies both on sensor measurements and periodic exchange of Cooperative Awareness Message (CAM) messages among vehicles. During the demo presentation, audience can configure ACC and CACC parameters and observe results of platoon simulation (e.g. average inter-car distance) in real-time. The demo illustrates 5G V2V communication requirements for high-density platooning by showing the impact of CAM message latency and reliability on CACC performance.

A Cloud Native Approach to 5G Network Slicing

  • Francini A.
  • Miller R.
  • Sharma S.

5G networks will have to support a set of very diverse and often extreme requirements. Network slicing offers an effective way to unlock the full potential of 5G networks and meet those requirements on a shared network infrastructure. This paper presents a cloud native approach to network slicing. The cloud ...

  • Wu Q.

Based on the physical model of a bulk reflective semiconductor optical amplifier (RSOA) used as a modulator in radio over fiber (RoF) links, the distributions of carrier density, signal photon density, and amplified spontaneous emission photon density are demonstrated. One of limits in the use of RSOA is the lower ...

How to preserve users' privacy while supporting high-utility analytics for low-latency stream processing? To answer this question: we describe the design, implementation and evaluation of PRIVAPPROX, a data analytics system for privacy-preserving stream processing. PRIVAPPROX provides three properties: (i) Privacy: zero-knowledge privacy (ezk) guarantees for users, a privacy bound tighter ...
