Uma Abordagem Adaptativa para Detecção de Falhas em Redes Veiculares Ad hoc

Eduardo CambruzziJean-Marie FarinesRaimundo José de Araújo MacêdoWerner Kraus Jr.

The capacity to detect component failures is an important characteristicfor fault-tolerant distributed systems. This article presents a failure detectorsuitable for Vehicular Ad hoc NETworks (VANETs) environments. Thedetector is composed of two parts: a detector for the communications link andthe failure detector proper. While the link detector verifies the validity of a linkbetween two process, the failure detector adapts itself to the mobility of the vehiclesand variations in the communication load in the network. Simulationresults show that the detector presents a low number of false-suspicious and areduced detection time.
