Abstract

Due to a very large number of connected virtual objects in the surrounding environment, intelligent service features in the Internet of Things requires the reuse of existing virtual objects and composite virtual objects. If a new virtual object is created for each new service request, then the number of virtual object would increase exponentially. The Web of Objects applies the principle of service modularity in terms of virtual objects and composite virtual objects. Service modularity is a key concept in the Web Objects-Enabled Internet of Things (IoT) environment which allows for the reuse of existing virtual objects and composite virtual objects in heterogeneous ontologies. In the case of similar service requests occurring at the same, or different locations, the already-instantiated virtual objects and their composites that exist in the same, or different ontologies can be reused. In this case, similar types of virtual objects and composite virtual objects are searched and matched. Their reuse avoids duplication under similar circumstances, and reduces the time it takes to search and instantiate them from their repositories, where similar functionalities are provided by similar types of virtual objects and their composites. Controlling and maintaining a virtual object means controlling and maintaining a real-world object in the real world. Even though the functional costs of virtual objects are just a fraction of those for deploying and maintaining real-world objects, this article focuses on reusing virtual objects and composite virtual objects, as well as discusses similarity matching of virtual objects and composite virtual objects. This article proposes a logistic model that supports service modularity for the promotion of reusability in the Web Objects-enabled IoT environment. Necessary functional components and a flowchart of an algorithm for reusing composite virtual objects are discussed. Also, to realize the service modularity, a use case scenario is studied and implemented.

Highlights

Recent technological advancement, a very large number of connected virtual objects, a significant amount of available data, and diverse service features enable the Internet of Things (IoT) infrastructure to create and offer services that facilitate society, economy, and daily living
Considering the abovementioned two factors, this paper proposes a logistic model that supports service modularity so that composite virtual objects (CVOs) can be reused in multiple domains where similar types of virtual object (VO) and their functionalities are available
Web of Objects (WoO) allows the use of semantic ontology to virtualize real-world objects, where multiple VOs are combined for service provisioning

Summary

Introduction

A very large number of connected virtual objects, a significant amount of available data, and diverse service features enable the Internet of Things (IoT) infrastructure to create and offer services that facilitate society, economy, and daily living. Maintaining these very large numbers of connected virtual objects, as well as creating and offering intelligent services in the. If new virtual objects need to be created for each new service, a number of virtual objects will be increased exponentially, which burdens networks and system performance. Virtual objects need to be reused under similar circumstances that can provide similar functionalities.
