Enhanced route reliability algorithm for vehicular ad hoc networks

Vehicular Ad Hoc Networks (VANETs) play a crucial role in facilitating road communication. By transmitting real-time traffic information to nearby vehicles and infrastructure, VANETs help address various real-world challenges, enhancing traffic management and road safety. To achieve this a secure and reliable scheme is needed. Reliable communication in VANER struggles with many problems like varying speed of vehicles, dynamic vehicle movement etc. To address this, we propose the Clustering Based Enhanced Route Reliability Algorithm (ERRAV), which uses clustering technique to improve route stability. In this geographical area is divided into clusters, each cluster is managed by a Cluster Head (CH). CH is selected based on signal strength, mobility, and vehicle density, ensuring stable communication. After clustering Reliable routes are established and maintained through periodic link monitoring, route updates, and backup routes. Simulations of ERRAV show the enhancement of scalability by reducing congestion, optimizing route discovery, and adaptation to network changes. EERAV been compared to AODV, DSR, and OLSR and experimental results show the reduced routing overhead, improves packet delivery, and minimizes link failures, making it highly effective in mobile environments.
