摘要

The integration of the Internet of Vehicles (IoV) with the Intelligent Transportation System (ITS) plays a significant role in ensuring safe and efficient traffic management. However, communication signals may encounter natural or artificial obstacles that result in uncovered road segments, where connectivity is lost. Even minor collisions in these unprotected areas can escalate into major incidents or traffic bottlenecks, especially when vehicles are traveling at high speeds on highways. Therefore, it is crucial to promptly inform the ITS of any adverse events occurring in these unnoticed areas. The importance of Store-Carry-Forward (SCF) techniques increases in such scenarios when uncovered patches exist and intervehicle distances exceed the communication range. Store-Carry-Forward (SCF) is a technique where vehicles temporarily store data and forward it when a connection is available. To address improved coverage and reduced latency using SCF, we propose a beacon-based Store-Carry-Forward Scheme to Deliver Emergency Messages via vehicle-to-vehicle (V2V) Communication for Highways (SCF-EMD). The proposed method aims to minimize congestion and delays in disseminating information about adverse events. It involves selecting high-mobility vehicles to travel across both covered and uncovered highway segments. The scheme integrates V2V and vehicle-to-infrastructure (V2I) communication to ensure rapid delivery of emergency alerts to ITS. SCF-EMD demonstrated significant improvements over existing schemes in Network Simulator \((NS-3)\) , achieving over \(10\%\) , \(16\%\) and \(5\%\) gains in information coverage, end-to-end delay, and packet delivery ratio (PDR), respectively.
