Abstract
The technological solutions and communication capabilities offered by the Internet of Things paradigm, in terms of raising availability of wearable devices, the ubiquitous internet connection, and the presence on the market of service-oriented solutions, have allowed a wide proposal of Location Based Services (LBS). In a close future, we foresee that companies and service providers will have developed reliable solutions to address indoor positioning, as basis for useful location based services. These solutions will be different from each other and they will adopt different hardware and processing techniques. This paper describes the proposal of a unified approach for Indoor Localization Systems that enables the cooperation between heterogeneous solutions and their functional modules. To this end, we designed an integrated architecture that, abstracting its main components, allows a seamless interaction among them. Finally, we present a working prototype of such architecture, which is based on the popular Telegram application for Android, as an integration demonstrator. The integration of the three main phases –namely the discovery phase, the User Agent self-configuration, and the indoor map retrieval/rendering– demonstrates the feasibility of the proposed integrated architecture.
Highlights
In a world where devices can communicate among them thanks to the Internet of Things (IoT) paradigm, the presence of an architecture that allows the discovery and composition of systems built upon smart devices represents a key enabling factor for the real development and deployment of IoT applications and to ensure security, reliability, and efficiency [1].The trend is towards increasingly smaller devices, a better energy efficiency, and a wider range of IoT-based services [2,3]
We argue that the meta-information characterizing the Infrastructure providing LBSs (ILBS) has to be standardized so that every User Agent can interact with ILBS from different vendors
The service performs a WiFi scans looking for SSIDs starting with the prefix ILBS- and it tries to decode the characters following the prefix as a URL (e.g., ILBS-https://tiny.cc/ipakjz is an example of a valid SSID)
Summary
In a world where devices can communicate among them thanks to the Internet of Things (IoT) paradigm, the presence of an architecture that allows the discovery and composition of systems built upon smart devices represents a key enabling factor for the real development and deployment of IoT applications and to ensure security, reliability, and efficiency [1]. We aim at increasing the overall user experience for location-based services with a solution designed to cooperate with multiple heterogeneous systems. We consider that such an approach offers several benefits with respect to closed solutions. E.g. increasing the accuracy of the system, increasing the reliability and the redundancy of the positioning, promoting the growth of a market of services based on indoor localization systems. To this end, we describe an abstract architecture and we identify some key-components, namely the ILS, the Map Server and the User Agent.
