Event-Based Adaptive Power Control in Vehicular Networked Systems With State-Dependent Bursty Fading Channels

摘要

This brief considers both safety and efficiency issues for vehicular networked systems (VNSs) where vehicles exchange information over vehicle to vehicle (V2V) wireless communication channels. One of the challenges to ensure system safety and efficiency lies in unreliable V2V fading channel conditions, which stochastically change as a function of the vehicle states and are subject to severe data rate drops. By adopting a bursty state-dependent fading model, this brief presents a novel event-based adaptive power control scheme. Under this scheme, the VNS assures efficient use of communication resources while preserving almost sure asymptotic stability. The benefits of the proposed scheme over other power policies are shown in a leader-follower formation control example.
