Enhancement in Quality of Routing Service in Vehicular ad-hoc Networks Based on the MPR Selection Algorithm of the OLSR Protocol

Abstract

In the transport domain, vehicles share a variety of information among themselves, including speed, road conditions, and accident data. Using the Vehicular Ad hoc Networks (VANETs), these vehicles effectively exchange this information. However, the issue lies in the quality of data transmission and reception. In another way, Enhancing Routing Services (ERS) improves the rate of data transmission and reception in VANETs. Our goal is to enhance routing services in VANETs based on the proactive Optimized Link State Routing (OLSR) protocol. This protocol relies on the concept of MultiPoint Relays (MPR) for neighbor selection and an intelligent algorithm for determining the shortest path between source and destination vehicles. Our idea consists of enhancing the MPR selection algorithm by increasing the maximum number of hops to three. We conducted simulations using the Simulation of Urban Mobility (SUMO) and the Network Simulator (NS3). The simulation results demonstrate favorable outcomes for the modified OLSR in various scenarios. We evaluated a set of metrics such as End-To-End Delay (E2ED), Packet Loss Rate (PLR), Overhead, and ERS.
