In this paper, we report the first complete version of a multi-hop broadcast protocol for vehicular ad hoc networks (VANET). Our results clearly show that broadcasting in VANET is very different from routing in mobile ad hoc networks (MANET) due to several reasons such as network topology, mobility patterns, demographics, traffic patterns at different times(More)
In ad hoc wireless networks, routes are discovered either by means of a periodic update between 1-hop neighbors or by using a reactive routing protocol which relies on an explicit route discovery process. Although the major advantage of a reactive protocol is the reduction in the routing overhead, the conventional flooding mechanism used to propagate the(More)
Ad hoc On-demand Distance Vector routing protocol (AODV) is a reactive routing protocol used in MANETs that makes use of Hello Messages for local Link connectivity. Every node in a network broadcasts hello messages to all its neighbours at a default hello interval of 1 second. However, this continuous broadcast leads to unnecessary energy consumption and(More)
Ad hoc wireless networking is currently a hot research area, especially because there is an increasing need for connectivity “anywhere” and, in particular, “anyhow.” While traditional networks have fixed nodes with wired connections (either optical fibers or copper lines), ad hoc wireless networks can be described as multi-hop wireless networks with mobile(More)
Due to their "on demand" nature, the reactive protocols for MANETs, incurred less overhead and hence are preferred over proactive protocols. Since reactive protocols rely on network wide flooding of routing messages, they suffer from the "broadcast storm" problem. Received signal strength based probabilistic flooding scheme named(More)
