In this paper we propose a hierarchical cloud architecture for integrated mobility, service, and trust management of service-oriented Internet of Things (IoT) systems. This architecture supports scalability, reconfigurability, fault tolerance, and resiliency against cloud node failure and network disconnection, and can benefit both network operators and cloud service providers. In particular, leveraging this architecture we develop a cloud-based trust protocol to provide trustworthiness assessment of IoT devices. With air pollution detection as an example IoT application, we demonstrate that our cloud-based trust protocol built upon the proposed cloud hierarchy outperforms existing distributed IoT trust management protocols.
