Scheduling Temporal Data with Dynamic Snapshot Consistency Requirement in Vehicular Cyber-Physical Systems

Abstract: Timely and efficient data dissemination is one of the fundamental requirements to enable innovative applications in vehicular cyber-physical systems (VCPS). In this work, we intensively analyze the characteristics of temporal data dissemination in VCPS. On this basis, we formulate the static and dynamic snapshot consistency requirements on serving real-time requests for temporal data items. Two online algorithms are proposed to enhance the system performance with different requirements. In particular, a resche… Show more

“…In the literature [30], Schneider et al present a multi-layered schedule synthesis scheme for mixed-criticality cyber-physical systems (MCCPS) so as to jointly schedule deadline-critical, and QoC-critical tasks at different scheduling layers. Liu et al [26] dive deep into the characteristics of temporal data dissemination in vehicular CPS and propose a scheduling algorithm to analyze the time bound for serving requests.…”

“…These predicting, scheduling and controlling technologies facilitated the implementation of various upper-layer applications. A few studies have concerned the information quality in VCPS, including timeliness [18], [19], consistency [20], and accuracy [21]. Nevertheless, to the best of our knowledge, none of the prior studies have investigated the tradeoff between the quality and cost of VCPS in ISAC-based vehicular networks.…”
