Abstract : In this paper we tackle the problem of data dissemination under both well-connected and intermittently connected ve- hicular ad hoc networks. For such a purpose, we propose HyDi, a data dissemination protocol suited for highway sce- narios. HyDi can seamless operate under both well-connected networks by applying broadcast suppression techniques in order to avoid contention at the link layer, and also at intermittently connected networks by applying store-carry-forward techniques, thus delivering messages even when an end-to-end path is non-existent. By means of simulation using the recently de ned IEEE 802.11p standard, we compare HyDi against the only two existing solutions in the literature - DV-CAST and SRD - and we show that HyDi has an overhead as good as DV-CAST, outperforms both protocols when considering the average delay under heavy tra cscenarios, decreases the average number of hops to deliver messages and can deliver data to almost all nodes in a given region of interest.
