Improving the Performance of Cluster Based Routing Protocol in VANET by Using Hybrid Algorithms

Abstract

Vehicular Ad hoc network are a subclass of mobile ad hoc networks that provide communications among nearby vehicles and between vehicles and nearby roadside equipment, although they differ from other networks due to their characteristics as well as challenging for designing such as high dynamic topology, frequent disconnected network, high mobility and so on. Because of high dynamic topology in VANETs design efficient routing protocol is challenging, this paper proposes improve the performance of cluster-based routing protocol in VANETs using hybrid algorithms to provide efficient routing protocol and increase network performance. Clustering is grouping object into classes of similar object or similar characteristic. By grouping comparable vehicles into numerous virtual groups, clustering technology is proven to be a viable way to increase routing reliability and scalability. Each cluster has a capital vehicle called a cluster head that is in charge of overseeing communication inside the cluster.The paper addresses the problem of improving the performance of cluster-based routing protocols in Vehicular Ad-hoc Networks (VANETs). While existing routing protocols have limitations, the authors propose a new algorithm that uses fuzzy logic and k-means clustering to address these limitations and enhance the performance of cluster-based routing protocols in VANETs. Overall, the statement of the problem is to improve the performance of cluster-based routing protocols in VANETs by proposing a new algorithm that can address the limitations of existing protocols and enhance the reliability and efficiency of communication among vehicles. The proposed solution in the paper is a new algorithm that uses fuzzy logic and k-means clustering to improve the performance of cluster-based routing protocols in Vehicular Ad-hoc Networks (VANETs). The algorithm is designed to address the limitations of existing protocols and enhance the reliability and efficiency of communication among vehicles. In the research we conducted simulations and compared the performance of the proposed algorithm with existing algorithms to evaluate its effectiveness. The findings demonstrate that, in terms of packet delivery ratio, the suggested method performs better than the current protocols with 1.5% in this case when the number of vehicles decrease the PDR increase, Throughput increase trough time than previous paper, and network lifetime will better increase and more stability. in this paper we suggest that the proposed algorithm can significantly improve the performance of cluster-based routing protocols in VANETs and provide suggestions for future work to investigate the algorithm's impact on different network parameters, extend it for multi-hop routing, evaluate it under different traffic scenarios, and investigate its security implications.
