Une approche beaconing avec échange de clés dans les réseaux ad hoc de véhicules

Abstract

Vehicular Ad-Hoc Networks (VANETs) are special forms of Mobile Ad-Hoc Networks (MANETs) that allows vehicles to communicate together in the absence of fixed infrastructure. In this type of network beaconing is the means used to discover the nodes in its neighborhood. Successful delivery of the message beacons containing speed, direction and position of a car is extremely important. Otherwise, routing information should not be modified/manipulated during transmission without detection, in order to ensure the routing information, messages must be signed and provided with a certificate to attest valid network participants. In this work we present a beaconing protocol with key exchange to prepare the generation of a signature to protect the routing information protocol ‘Greedy Perimeter Stateless Routing’.
