文摘

The main objective of VANET networks is to improve road safety as well as transportation efficiency through the use of wireless communications technologies and the emergence of low cost embedded sensors. Thus, the design of an efficient data dissemination protocol, that informs vehicles about interesting safety events, is of paramount importance. The thriving challenge would be to maximize the delivery ratio by avoiding as far as possible the broadcast storm problem. A scrutiny of the literature wealthy number of approaches highlights that all of them fail to fulfill with a critical requirements. In this paper and to palliate this shortage, we introduce a new infrastructure-less Geocast protocol that send messages only to vehicles in the Zone of Relevance (ZOR) with a minimum overhead cost. Our protocol stands in reaching a high delivery ratio as well as a high Geocast precision by only sending messages to vehicles in the Zone of Relevance (ZOR) with a minimum overhead cost. Carried out experiments show that our protocol outperforms its competitors in terms of effectiveness and efficiency.
