Abstract

IoT (Internet of Things) is becoming increasingly prevalent in everyday life, with many commercialized IoT platforms available for use. In this paper, we propose a novel hierarchical IoT platform under a single administrating entity to provide scalability to an edge-based service-oriented IoT platform. To enable communication and resource sharing between edges while preserving the privacy benefit of the edge-based platform, a new type of service, called super service is introduced. And the scheduling problem of service requests to devices and a proposed solution are presented. To evaluate the proposed platform, a simulation framework is developed. Through a smart campus test-bed and extensive experiments with the simulation framework, the viability of the proposed platform is demonstrated.
