A PSO enable multi-hop clustering algorithm for VANET

Abstract

VANET (vehicle ad-hoc network) is an emerging technology in today's intelligent transport system. In VANET, there are many moving nodes, which are the vehicle running on the road. They communicate with each other to provide the information to drivers regarding the road condition, traffic, weather, and parking. VANET is a kind of network where moving nodes talk with each other with the help of equipment. There are various other things that also make VANET complete like OBU (onboard unit), RSU (road aside unit), and CA (certificate authority). In this paper, a new PSO enable multi-hop technique is proposed that helps VANET to select the best route and find the stable cluster head and remove the malicious node from the network to avoid false messaging. The false can occur when there is a malicious node in a network. Clustering is a technique for making a group of the same type of node. This paper is based on PSO-enabled clustering and its importance in VANET. While using this approach in VANET, it has increased the 20% packet delivery ratio.
