Emergency Data Transmission Mechanism in VANETs using Improved Restricted Greedy Forwarding (IRGF) Scheme

One of the most critical tasks in Vehicular Ad-hoc Networks (VANETs) is broadcasting Emergency Messages (EMs) at considerable data delivery rates (DDRs). The enhanced spider-web-like Transmission Mechanism for Data (TMED) based on request spiders and authenticated to create shortest route path between source vehicle target vehicles. However, adjacent allocation DDR only it not clear whether each honest or not. Hence, this article, Improved Restricted Greedy Forwarding (IRGF) scheme proposed with help trust computation TMED. reputation score value estimated successfully broadcast emergency data. vehicles’ position, velocity, direction, density, score, are fed a fuzzy logic (FL) scheme, which selects trusted node as forwarding EM destination Finally, simulation results illustrate TMED-IRGF model’s efficiency compared state-of-the-art models terms different network metrics.
