A Novel Authentication and Communication Protocol for Urban Traffic Monitoring in VANETs Based on Cluster Management

City zones have become increasingly overcrowded due to the extensive population widening ratio and swift relocation of people from villages. The traffic monitoring process is a significant issue in these areas massive flow on roads. This research proposed cluster-based improved authentication communication protocol for an Intelligent Transportation System Vehicular AdHoc Networks (VANETs). Our primary objective optimize resource sharing vehicular communication. We enhanced reliability, scalability, stability fast-moving VANETs by introducing routing protocols Vehicle-to-Vehicle (V2V) Vehicle-to-Infrastructure (V2I) communications. used third-party certification authority vehicle address security privacy concerns. support minimizes end-to-end (E2E) delay route request reduces link failure. protocol’s leading yield includes throughput enhancement, TCP Socket Initialization time minimization, handshake response speedup, DNS lookup improvement. are centered short-range peer-to-peer (P2P) wireless 400 m radius cluster. They include innovative P2P communications VANET using minimized resources. deliver secure mechanism with securely generated key provided authority. Furthermore, we developed RESTful APIs implementation purposes also offered implemented algorithms regarding V2V V2I Ultimately, evaluated performance our experiments.
