IDVR: An Intersection Dispatch-Based VANET Routing Protocol

In this paper, we present a modified position-based routing scheme called Intersection Dispatch-based VANET Routing(IDVR) protocol focusing on the needs of in-time information delivery and emergency message dissemination in urban scenarios. There are two primary contributions to enhancing VANET performance in our algorith. First, a fixed node located at an intersection is used for monitoring the connectivity of branches belonging to the intersection and the path with the highest link-quality is selected automatically based on Far-reaching Detection Method(FDM).

Second, regarding the problem of abrupt link interruptions, store-and-forward scheme is used to improve the performance of packet delivery ratio and overload. Our analysis indicates that the new protocol is realiable and it provides significant improvements for efficient transmissions compared with traditional VANET routing protocols.
