Vehicular Ad-Hoc Network (VANET) is becoming a promising technology for improving the efficiency and the safety of Intelligent Transportation Systems (ITS) by deploying a wide variety of applications. Smart vehicles are expected to continuously exchange a huge amount of data either through safety or non-safety messages dedicated for road safety or infotainment and passenger comfort applications, respectively. One of the main challenges posed by the study of VANET is the data dissemination design by which messages have to be efficiently disseminated in a high vehicular speed, intermittent connectivity, and highly dynamic topology. In particular, broadcast mechanism should guarantee fast and reliable data delivery within a limited wireless bandwidth in order to fit the real time applications' requirements. In this work, we propose a Simple and Efficient Adaptive data Dissemination protocol called "SEAD". On the one hand, the originality of this work lies in its simplicity and efficiency regardless the application's type. Simplicity is achieved through a beaconless strategy adopted to take into account the surrounding vehicles' density. Thanks to a metric locally
However, in REF authors propose a simple and efficient adaptive dissemination (SEAD) protocol in the vehicular environment.
