Performance Modeling Extension of Directory Facilitator for Enhancing Communication in FIPA-Compliant Multiagent Systems
Petr Kadera, Petr Novák · IEEE Transactions on Industrial Informatics · 2016
The growing adoption of highly distributed and intelligent industrial systems frequently denoted as Industry 4.0 or Industrial Internet of Things brings great opportunities as well as new research questions because connection of single devices into a cooperating community creates much larger and complex systems with new challenges regarding verification and security. This paper proposes a method to solve problems related to setup of timeouts used in communication protocols. The static setup is replaced with an enhancement of directory facilitator that in cooperation with a specialized sniffer agent continuously monitors the system load and eventually postpones starts of new tasks. This precaution eliminates saturation of computational resources and preserves the maximal reachable system performance. The proposed method is demonstrated through a simulation of a chilled water system using a test-bed of six minicomputers Raspberry Pi that host agents implemented in Jade.
