Enhancing The Olsr Protocol For Efficient Data Dissemination In Vanet Using Load Balancing Scheme

Abstract

By enabling communication between vehicles and infrastructure, VANETs (Vehicular Ad Hoc Networks) have emerged as a feasible solution for increasing road safety and traffic efficiency. The Optimized Link State Routing protocol is widely used in VANETs to create and maintain communication channels between vehicles. However, because of the evolving character of network topology and the limited bandwidth available, efficient data dissemination in VANETs remains a challenge. We provide an upgraded version of the OLSR protocol with a load balancing method to increase data dissemination in VANETs in this study. VANET, which is assisting in the reconfiguration of Intelligent Transportation Systems, is considerably improving the performance and efficiency of transportation systems. The goal of this thesis is to improve the OLSR protocol for efficient data distribution on VANETs by employing a load-balancing technique with a high-performance delivery ratio, low end-to-end delay, and minimal overhead. It presents a method for improving the Optimized link state routing protocol and efficient data dissemination. To accomplish this, we present a unique load-balancing method that considers multiple parameters such as dynamic link metrics, fairness index, and load weight as a parameter. To improve data distribution in the network, the system dynamically adjusts routing paths and transmission rates. The SUMO simulator was used to generate mobility, and NS3.31 was utilized to simulate our network using OSM frameworks
