VAR²: Novel Vehicular Ad-Hoc Reliable Routing Approach for Compatible and Trustworthy Paradigm

Communications and routing protocols for vehicular ad-hoc networks (VANETs) are affected by dynamic vehicular constraints like high mobility, efficient delivery, reliable path, and trustworthiness. We propose a novel 'VAR2' scheme that enables autonomous trust and selects routes with the longest connectivity time to efficiently deliver messages. In multi-hop and multi-path VANETs, the proposed scheme ensures reliability by selecting compatible and trustworthy routes with minimum additional communications. Our Python simulations on sparse and dense SUMO traffic traces show that the proposed VAR2 routes have 100400s connectivity with only 34 hops and achieve 615% PDR, which are comparatively more efficient results than that of existing schemes.
