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.
Towards Fast and Reliable Multi-hop Routing in VANETs
- 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. SYSTEM REQUIREMENTS: HARDWARE REQUIREMENTS: System : Pentium Dual Core.
