SP3 - SINTECH

SP3

The objective of the SINTECH subproject is to analyse communication technologies, to adapt and enhance them in order to properly integrate them into the vehicle and infrastructure platforms. Prototypes will consist mainly in software implementations and will be a contribution to SAFEPROBE and INFRASENS activities, where such software modules will be integrated into the vehicle and infrastructure prototypal platforms.

Main technologies considered in SINTECH are:

  • Co-operative relative localisation: highly accurate and reliable localisation system; Reliable, very accurate, real-time relative positioning
  • GNSS-based Positioning (GPS, Galileo)
  • Communication-based Positioning (UWB, WLAN)
  • Image-based Positioning (Landmarks recognition)
  • Local temporary vehicle maps for safety applications

4 Layers

Ad hoc dynamic vehicle-vehicle-infrastructure network; in order to exchange time-critical safety related information this requires:

  • Reliable, fast, secure, potentially low cost protocols for local V2V and V2I communication
  • Routing protocols with multi-hop forwarding and geo-cast functionalities Geographical addressing
  • Channel control (multi channel operation, power control, data rate selection)
  • Priority access

The candidate communication technology is IEEE 802.11p. With he ECC Decision of 14 March 2008 on the harmonised use of the 5875-5925 MHz frequency band for ITS a dedicated frequency band for safety related V2V and V2I communications is available.
