Intelligent Vulnerability Analysis for Connectivity and Critical-Area Integrity in IoV

Abstract

The large-scale connectivity of Internet of Vehicles (IoV) is an important challenge for the Intelligent Transportation Systems (ITS). Intelligence vulnerability analysis is an excellent solution. However, existing methods for analyzing connectivity vulnerability have ignored the existence of critical areas in the system. Due to the heterogeneities of the IoV environments and services, the failure of some specific areas may seriously damage connectivity and system performance. To this end, in this paper we focus on both the dynamic connectivity and the critical-area integrity, and propose an intelligent vulnerability analysis method to effectively identify the critical area of extreme vulnerability. Specifically, we consider an intelligent analysis scenario in which roadside servers continuously learn IoV heterogeneous environment and dynamic topology, and then translate the learning results into a flexible disruption cost problem. Based on this, we utilize the spectral partitioning method to identify the minimum-cost set of topological elements whose failure not only severely damages system connectivity but also disrupts its critical areas. Furthermore, we confirm that the identified set can be used to optimize disruption cost problem, thus intelligently improving vulnerability. Simulation results show that our proposed method can effectively identify vulnerable elements and prevent significant loss in the IoV system connectivity and performance.

Insights of 6G and artificial intelligence-based internet-of vehicle towards communication

“…The model deals with task management in IoV using multi-blockchain where the throughput is maximized and overhead is controlled. Similar line of research work is also carried out by Liu et al [31] emphasizing over the connectivity among the vehicles in critical area. The study implements a spectral partitioning method to find out the optimal topological cost for addressing possible vulnerabilities in communication system of an IoV.…”
