Link Quality Driven Hybrid Scheme for Multi-hop Message Broadcast in VANETs

Abstract

A radical transformation is foreseen in the automotive industry for which Vehicular Ad hoc NETworks (VANETs) is a major attraction. This is due to its potential to support a wide range of applications that can lead towards new driving and travelling experiences. Multi-hop broadcasting approach is expected to be the primary mode of communication among vehicles. Suitable choice of the next-hop relay nodes is an essential part for the design of multi-hop messaging schemes in VANETs. This greatly impacts the reception of the broadcasted messages, particularly when evaluated on high node density networks. This research proposes a link quality driven hybrid scheme that attempts to systematically combine multiple link quality based message dissemination schemes in a particular order. The proposed scheme attempts to improve message reception performance over stringent communication conditions. Our performance evaluation indicates that the suggested scheme improves messages reception over high node density networks compared to the existing conventional versions.
