Trust and Reputation Management in IoT Using Multi-agent System Approach

The Internet of Things (IoT) facilitates the provision of sophisticated services by linking an extensive array of diverse smart objects. As IoT devices become more intelligent, they will have the ability to communicate and cooperate with each other. As such, it is important to maintain effective cooperation among network deployed devices and ensure that they operate in a reliable and dependable fashion. In this paper, we describe IoT-CADM, an IoT agent-based decentralized trust and reputation model to select the best service provider for a particular service based on multi-context quality of services. We evaluated the performance of our model in a simulated smart factory environment against three widely-known models ReGret, SIoT and R-D-C and the result showed that our model outperformed these models.
