Receiver-driven broadcast for vehicular applications

Abstract

Broadcasting/multicasting may be an efficient way to disseminate delay-sensitive content in vehicular networks. However, conventional broadcasting schemes have suffered from reliability issues, since they cannot go along with ACK and RTS/CTS. In this paper, we design a novel receiver-driven broadcast scheme for periodic messaging in vehicular applications, where receivers request broadcasting to their neighbors and data is broadcast as a response. Via simulation study, it is shown that the proposed scheme effectively 1) controls contention and 2) mitigates hidden node effects in broadcast communication.
