Approach for Semantic Interoperability Testing in Internet of Things

Abstract

The Internet of Things (IoT) systems must support deployment of new services capable of supporting multiple, scalable and cross-domain applications. But the current IoT applications and services are highly fragmented in terms of platform development, data and security. Semantic interoperability is widely acknowledged to be the key to address the challenges and achievethe full potential of the IoT systems. Although semantic interoperability has received increased attention in the recent days, the current IoT systems lack means for testing that. This paper describes our approach for semantic interoperability testing in the IoT. We have identifiedthree main requirements for semantic tests - (i) lexical check, (ii) syntactic check and (iii)semantic checks. To examine semantic interoperability between IoT systems, we define two typesof tests - (i) semantic conformance test and (ii) interoperability test. The operational stepsare presented along with detailed test scenarios.
