Model Based Energy Consumption Analysis of Wireless Cyber Physical Systems

摘要

Wireless mesh networks begin to be used as an infrastructure of cyber-physical systems. A critical issue in developing wireless cyber physical systems (WCPSs) is the limited amount of energy available in the nodes. Energy consumption analysis can help designer to conduct a power-aware design process. In this paper, we propose a model based energy consumption analysis framework at architecture level for WCPSs. We extract event chains from the architecture model. With the energy consumption model for processing each type of event, we can estimate the energy consumption for each control loop and each node, as well as the overall energy consumption. All these energy consumption indexes can help us to design a performance and energy consumption balanced WCPS.
