QoS Aware Optimized Clustering Algorithm for Reliable Transmission in VANET

Abstract

Introduction: The paper addresses the need for an efficient and reliable Media Access Control (MAC) protocol for Vehicular Ad Hoc Networks (VANETs) to support safety-related applications and reliable communications. The IEEE 802.11P standard lacks sufficient spectrums for reliable information exchange in congested channels.

Objectives: It aims to improve energy efficiency, channel utilization, subcarrier collision, and lossless data transfer for enhanced communication.

Methods: The paper proposes a Quality of Service (QoS) aware clustering algorithm (HOQC-MAC) for VANETs using an optimization algorithm. The proposed protocol utilizes the Tree-Seed Induced Coyote Optimization (TSCO) algorithm for clustering for enhancing the energy efficiency. 

Results: Simulation results show that HOQC-MAC outperforms existing protocols in terms of latency, packet delivery ratio and bandwidth utilization, enhancing VANET communication.

Conclusion: The HOQC-MAC protocol demonstrates significant improvements over existing protocols, addressing challenges in VANET communication.
