Development of Augmented Reality Underground Facility Management System using Map Application Programming Interface and JavaScript Object Notation Communication

With the rapid development of IT in the modern society, various kinds of information such as smart information age are provided in real time regardless of time and place. Especially, various IT devices and mobile devices using the ubiquitous concept are being widely used in real life and helping to make life convenient. Currently, various ubiquitous services and management schemes are being tried in the government business field. This paper was performed to propose an augmented reality-based system construction and service environment plan for the management of underground facilities such as gas, electricity, communication, water supply, sewerage, heating, and oil pipelines. To do this, the author used Map API and JSON communication technique. JSON can be used in JavaScript programs without parsing or serialization. Also, JSON is a text-based way to represent JavaScript object literals, arrays, and scalar data. As a result, it can be transmitted in a format that can be interpreted in fields that utilize various types of data. Using this JSON, an augmented reality-based underground facility management system was implemented. In other words, it is a system that can find and modify the location of underground objects without drawing drawings in the field through communication between the tablet and the server. Especially, it suggested a method to provide and manage the location information of GIS (NGIS, KLIS) system and the facilities embedded in the underground, and attribute information by replacing the location mark used in existing underground facilities. Through the augmented reality based underground facility management system, it is expected to be effective in terms of practicality, economics, real - time network, information provision and management, and prevention of major accidents. In addition, it will be an effective method for updating and maintaining information related to underground facilities. Finally, by applying the augmented reality-based underground facility management system, it is possible to precisely measure the underground facility survey and condition for an existing buried pipe or a new public pipeline. Through augmented reality technology, it is possible to check the facilities of obstacles as if they were right in front of you. In addition, facility management, history management, and on-site management are possible at once, and it is characterized by convergence with other IT and quick decision-making by integrating the management system

IoT DEVICE MANAGEMENT AND CONFIGURATION

As the number of IoT devices grows, the management and configuration of IoT devices becomes crucial in resource constraint networks. It is hard to manage and configure a large amount of heterogeneous resource constraint IoT devices because people need to know how they connect to each other, what internet-enabled services are available to provide, and how people interact with things through the internet. The thing-centric approach focuses on user experience when engaging things, but the cloud- centric approach switch the focus to IoT services that can process data streams collected from things and applications that help get people joined in the IoT world. To manage IoT populations effectively in a centralized manner, not only does it mean that moving computational power closer to the edge is a way to reduce bandwidth and latency, but it also implies that it is necessary to build an architecture which can scale and manage tons of connected devices by a uniform interface. In particular, RESTful Web services can provide a uniform interface that operates resources by HTTP methods. For example, users can read and write data by a uniform interface, and a flowerpot can write data and be triggered to water plants by a uniform interface. Thus, in the scope of IoT, embedded middleware can implement uniform interface by REST model. Virtualizing physical things has emerged as a design pattern to build IoT systems. Resource less constraint devices are capable of being virtualized with enough CPU power, memory, networking, but they are more expensive and power consuming. However, resource highly constraint devices take advantage of low energy consumption and cheaper price, but they cannot be virtualized because they do not have ability to even run a single multi-threaded program. Therefore, it is very important to select the right platforms for the right roles. In our case, we use Raspberry Pi 3 as a middleware and Nordic nRF52832 as a BLE endpoint. In this thesis, a REST-based IoT management system based on Service-Oriented Architecture is built, and the performance of the system has been tested, including the response time of HTTP GET and POST requests of the centralized server in a Fog domain and a script engine onto a BLE-enabled endpoint

RESTful Wireless Sensor Networks

Sensor networks have diverse structures and generally employ proprietary protocols to gather useful information about the physical world. This diversity generates problems to interact with these sensors since custom APIs are needed which are tedious, error prone and have steep learning curve. In this thesis, I present RESThing, a lightweight REST framework for wireless sensor networks to ease the process of interacting with these sensors by making them accessible over the Web. I evaluate the system and show that it is feasible to support widely used and standard Web protocols in wireless sensor networks. Being able to integrate these tiny devices seamlessly into the global information medium, we can achieve the Web of Things

Reprogramming Low-end IoT Devices from the Cloud

International audienceThe Internet of Things (IoT) consists in a variety of smart connected objects, among which a category of low-end devices based on micro-controllers. The orchestration of low-end IoT devices is not straightforward because of the lack of generic and holistic solutions articulating cloud-based tools on one hand, and low-end IoT device software on the other hand. In this paper, we describe such a solution, combining a cloud-based IDE, graphical programming, and automatic JavaScript generation. Scripts are pushed over the Internet and over-the-air for the last hop, updating runtime containers hosted on heterogeneous low-end IoT devices running RIOT. We demonstrate a prototype working on common off-the-shelf low-end IoT hardware with as little as 32kB of memory

Quantum node portal- Devices and information management

An Internship in a European Company for developing a Web application-Domatica Global Solutions, Lisbon was undertaken to complete the Master’s Degree of Computer Engineering-Mobile Computing in the Polytechnic Institute of Leiria. The team Domatica deals with providing IoT solutions used for monitoring, controlling and collecting the data from the IoT gateways. The present work aims to develop a Web application for client’s side. The Web application named Quantum Node Portal is developed for the Devices and Information management. It provides access to the clients to their IoT gateways. Clients can monitor their devices, get various information, also can access the Portal for claiming their IoT gateways. The present work was developed using various technologies such as PHP framework named Laravel and several languages

IoT Middleware Platforms for Smart Energy Systems: An Empirical Expert Survey

Middleware platforms are key technology in any Internet of Things (IoT) system, considering their role in managing the intermediary communications between devices and applications. In the energy sector, it has been shown that IoT devices enable the integration of all network assets to one large distributed system. This comes with significant benefits, such as improving energy efficiency, boosting the generation of renewable energy, reducing maintenance costs and increasing comfort. Various existing IoT middlware solutions encounter several problems that limit their performance, such as vendor locks. Hence, this paper presents a literature review and an expert survey on IoT middleware platforms in energy systems, in order to provide a set of tools and functionalities to be supported by any future efficient, flexible and interoperable IoT middleware considering the market needs. The analysis of the results shows that experts currently use the IoT middleware mainly to deploy services such as visualization, monitoring and benchmarking of energy consumption, and energy optimization is considered as a future application to target. Likewise, non-functional requirements, such as security and privacy, play vital roles in the IoT platforms’ performances
