Alexandre Mouradian (Research Associate, L2S), on the subject “A stochastic geometry approach to model Broadcast CSMA/CA Full-Duplex in Vehicular Networks".
Summary: Broadcast traffic in IEEE 802.11-based vehicular networks is known to suffer from poor performance due to the lack of recovery mechanisms from packet losses in the standard Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) protocol. This has a detrimental impact on cooperative vehicular safety applications that build on the reliable periodic broadcasting of status messages by neighboring vehicles. Recently, Full-Duplex (FD) techniques have been proposed to let a sending vehicle sense the channel while transmitting, thus enabling collision detection and improving the broadcast CSMA/CA performance. In this work, we de ne a stochastic geometry model that captures the FD-enabled collision detection capability on board the vehicles while accurately characterizing the interference power generated on a road segment and the dynamics of the backoff mechanism for broadcast packet re-transmissions. The model provides helpful insights into the FD protocol behavior highlighting a clear relationship between the settings for the carrier sense threshold and the collision detection threshold and the number of successful receivers on the road.
