Cohort-Based Construct for Vehicular Cyber-Physical Systems

Ensuring human life safety is inexorably the most critical objective of Intelligent Transportation System (ITS), which makes Intelligent Vehicular Network (IVN) the cornerstone of such system. Hence, in order to overcome network Quality of Service (QoS) degradation issues, several networking models for IVN have been proposed in the literature, namely clusterbased construction, cloud-based construction and platoon-based construction. Nevertheless, such constructions present several limitations, in terms of timeliness, connectivity and reliability, especially in critical environments. Therefore, we propose in this paper the design of a distributed construction based on “cohorts” and Neighbor-to-Neighbor (N2N) Communication, and we present the required cohort-managements distributed algorithms that ensure optimal IVN cohort-structuring and efficiency.
