Abstract :
Overcoming problems associated with network dynamicity and unreliable channels has been a challenge for data dissemination protocols in vehicular networks. In this paper, we present an overview on the most interesting solutions that have been proposed to perform data dissemination in this environment. Starting from this analysis, we present a novel approach that can efficiently address a reliable communication even in high dynamic networks. The new approach is based on the exploitation of a peculiar characteristic of rateless codes. In particular, the proposed method uses the orthogonality of the encoded sets of symbols generated by different random seeds. In this way, portions of the information can be disseminated even if this has not been decoded yet. In fact, an easy management of the communication of these sets among nodes enhances the reliability of the communication as well as the speed of the information dissemination. In this work, we present the idea of this innovative approach and we provide results that show the advantages of using it over other solutions.
