FELICIA: Feasibility study of latency-critical connected vehicle applications in MONROE

Connected cars and cooperative intelligent transport systems (C-ITS) can make road traffic safer and more efficient, but require the mobile networks to handle time-critical applications. In the FELICIA-project we measure what network performance connected cars can expect in today’s mobile networks. We also study the possible gain of using multiple network operators for these type of applications.

The FELICIA -project is a measurement study using the MONROE mobile broadband measurement testbed with  measurement devices on buses in Värmland, Sweden and Turin, Italy. MONROE (Measuring Mobile Broadband Networks in Europe) is a European Horizon 2020 project and the FELICIA project is one of the 15 projects selected in the Second MONROE Open Call for Experiments and Extensions.

Measurement study

Using the  MONROE testbed, we conduct a multi-access measurement study on buses. We study multi-access where we triplicate the data and send it in parallel over three operators. In our experiments, warning messages (5.6KB, Datex II) are repeatedly transferred from moving buses to a stationary server in Stockholm. We measure transaction times and availability. We perform the experiments with three different protocols: UDP, TCP, HTTPS.

Measurement results

  • Our results show that having access to several operators in parallel can substantially improve communication performance for connected vehicles in today's 3G/LTE cellular networks.  
  • Our results also show that if we have access to three operators but for each transaction only choose one operator (the one with best access technology and best signal quality) then we can significantly improve availability and transaction times compared to the individual operators.
  • The measurements show that even though some operators have good average performance, multi-access makes a big difference because for many connected vehicle applications it is important to always have good performance (and not only half of the time).
