The document proposes a new multi-hop broadcasting protocol called the Intelligent Forwarding Protocol (IFP) for disseminating safety messages in vehicular ad-hoc networks (VANETs). IFP exploits handshake-less communication, ACK decoupling, and efficient collision resolution to significantly reduce message propagation delays and improve packet delivery ratios compared to existing schemes. The paper presents an in-depth analysis and optimization of IFP using theoretical modeling, simulations, and real-world experimentation.

1. Towards Fast and Reliable Multi-hop Routing in VANETs
ABSTRACT:
In Vehicular Ad-hoc Networks (VANETs), fast and reliable dissemination of
safety messages is a key step toward improving the overall road safety. In a highly
dynamic VANET environment, safety message dissemination in a multi-hop
manner is a challenging and complex problem that has gained significant attention
recently. Many protocols and schemes have been proposed to efficiently share
safety messages among vehicles. However, most existing techniques do not
perform well under real-world traffic conditions, or perform adequately only under
very limited scenarios and traffic conditions. This research proposes a highly
efficient and reliable multi-hop broadcasting protocol, Intelligent Forwarding
Protocol (IFP), that exploits handshake-less communication, ACK Decoupling and
an efficient collision resolution mechanism. In this research, IFP has been
extensively studied and evaluated to establish its robustness and superiority over
existing schemes. A key contribution of this paper is to present an in-depth
analysis and optimization of IFP using theoretical modeling, thorough simulations,
and extensive real-world experimentation. With IFP, the message propagation
delay is significantly reduced and packet delivery ratio is drastically improved.
