A Role-based Trust Model Assessing IoA Services: First Results on Real MAS Implementation by Using ROS 2.
EWSN '23 Proceedings of the 2023 INTERNATIONAL CONFERENCE ON EMBEDDED WIRELESS SYSTEMS AND NETWORKS(2023)
Abstract
IoA (Internet of Agents), combining MAS (Multi-Agent Systems) and IoT (Internet of Things), aims to provide an environment where diverse services can be performed and evaluated through heterogeneous agents’ cooperative participation. Given this, IoA requires a mechanism monitoring agents’ real-time behaviors to prevent undesired activities caused by compromised ones. This paper proposed a trust model to detect agents’ misbehavior by taking their roles into consideration, namely SP (Service Provider), SR (Service Rater), and SR+SP. Moreover, we conducted a real MAS implementation by using ROS 2 (Robot Operating System) to verify the preliminary results of SR and SP agents’ trust evaluation.
