An Event-Driven Service Provisioning Mechanism for IoT (Internet of Things) System Interaction

Abstract

The heterogeneity, large scale, and resource constraint of IoT environment raise some issues which hinder its development. We focus on two issues among them: 1) most of the existing IoT applications are “silos”, that is, wireless sensor and actuator network resources and applications are tightly coupled, applications cannot share and reuse resources and interact with each other and 2) how to efficiently disseminate the sensing information among the information providers and consumers, and rapidly respond to changes in the physical world. This paper proposes a multilevel and multidimensional model-based service provisioning platform, which can access large-scale heterogeneous resources and expose their capabilities as light-weighted services. Moreover, it presents a unified message space to facilitate the on-demand dissemination and sharing of sensing information in distributed IoT environment. The platform supports applications to share and reuse resources and provides the basic infrastructure for the IoT application pattern: inner-domain autonomy and inter-domain coordination.
