Um Simulador para o Cálculo e Otimização da Age of Information (AoI) em Sistemas Ciberfísicos
Abstract
The Age of Information (AoI) emerges as a new concept and set of metrics that represent the degree of freshness that a monitor has in relation to a remote entity or process that sends updates in a periodically way. These metrics can be applied in the evaluation of Cyber-Physical Systems (CPS), such as a monitoring system composed of several sensors, a network and a monitor. Most of the works in the literature use an analytical approach, obtaining exact expressions for AoI. This approach, however, is limited by the difficulty encountered in modeling as the CPS under study becomes more complex, motivating the use of other evaluation methods, such as the use of simulations. Thus, this work proposes a simulation tool based on a computational model for the evaluation of AoI in CPS. Such a tool is capable of evaluating any kind of system, also using several package management techniques present in the literature for the optimization of AoI. Finally, the tool also returns a statistical analysis of the simulation accuracy.
