V-Gmir: Geographic Multipath Interference-Resilient Routing For Inter-Path Interference in Vehicular Ad-Hoc Networks

Abstract

Particularly with the difficulties presented by dynamic topology and rigorous quality-of- service (QoS) criteria, Vehicular Ad-Hoc Networks (VANETs) depend on strong routing techniques to satisfy the high expectations of current vehicle applications. One practical way to guarantee dependable communication in VANETs is via cross-layer multipath routing. But because wireless communication is broadcast, inter-path interference may seriously reduce performance, therefore impacting many paths concurrently. Furthermore complicating routing in VANETs are low-power wireless communications' unreliability, asymmetry, and error-prone character. In this work, we offer a new routing technique intended to solve inter-path interference in VANETs: V-GMIR (VANET Geographic Multipath Interference-Resilient Routing). Along with a neighbor identification system, the V-GMIR protocol consists on a route finding module with improved RRQ and RRP algorithms. This multi-layer system chooses forwarding nodes based on geographic distance, vehicle speed, and connection quality measurements, therefore lowering interference across closely located paths. V-GMIR provides a more effective answer to the Hidden Node Problem (HNP) at the sink node than conventional protocols, therefore removing the necessity for RTS/CTS handshakes. V-GMIR improves general network dependability and performance by maximizing route selection and guaranteeing reliable connection quality estimations, therefore offering a potential solution for next-generation vehicle communication systems.
