Provision of dependability guarantees in iot-based service-oriented environments

Abstract

The IoT-based environments are mainly characterized by vertically oriented closed platforms/systems, also referred to as silos. This hinders the realization of an IoT environment where IoT platforms, objects, service and network resources from multiple providers could be easily interconnected, combined and serve multiple stakeholders. Moreover, in the cases of interconnected platforms one of the key limitations refers to dependability given the diversity and heterogeneity of the underlying resources and devices as well as the IoT management systems on top. In this paper, challenges and enablers are discussed to facilitate dependable federated environments, as well as an approach to enable end-to-end federation of IoT environments. The latter aims at allowing the sharing and optimization of the available resources, while meeting the multi-dimensional constraints emerging from different platform providers, stakeholders and applications. The proposed approach is also enhanced with a solution to ensure dependability based on the so-called semantic shims. The applicability of the proposed approach is discussed through a real-world scenario targeting supply chain management in ports.
