A novel hierarchical edge-based architecture for service oriented IoT

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.
