Developing an internet of things (IoT) service system based on spatial context

Abstract

The Internet of Things (IoT) is considered to be one of the most significant fields in modern research. The IoT offers innovative services via the networking of various objects; such connectivity had heretofore been impossible, as each object had traditionally been disconnected from its possible companions. According to the IoT concept, all existing objects can be connected both to the Internet and to other objects in the built environment. However, existing studies have ignored the importance of spatial information, which serves to limit not only users’ behaviors but also the services offered to them. All IoT devices are deployed within the built environment and can be executed in architectural spaces consisted by building components. In order to develop advanced IoT services, it is essential to understand the spatial context. This research aims to develop an IoT service system that is based on spatial information. The majority of existing IoT services consist of one-to-one services offered to users via their devices; this study aims to improve the quality of these services by utilizing spatial information. This study also intends to establish that IoT service systems can determine a user’s situation by analyzing the user’s location, thereby providing the user with more appropriate services than ever before. This is a form of LBS (Location Based Service) that utilizes spatial information as a semantic location map.
