State of the Art, Trends and Future of Bluetooth Low Energy, Near Field Communication and Visible Light Communication in the Development of Smart Cities

The current social impact of new technologies has produced major changes in all areas of society, creating the concept of a smart city supported by an electronic infrastructure, telecommunications and information technology. This paper presents a review of Bluetooth Low Energy (BLE), Near Field Communication (NFC) and Visible Light Communication (VLC) and their use and influence within different areas of the development of the smart city. The document also presents a review of Big Data Solutions for the management of information and the extraction of knowledge in an environment where things are connected by an “Internet of Things” (IoT) network. Lastly, we present how these technologies can be combined together to benefit the development of the smart city

Raising awareness for water polution based on game activities using internet of things

Awareness among young people regarding the environment and its resources and comprehension of the various factors that interplay, is key to changing human behaviour towards achieving a sustainable planet. In this paper IoT equipment, utilizing sensors for measuring various parameters of water quality, is used in an educational context targeting at a deeper understanding of the use of natural resources towards the adoption of environmentally friendly behaviours. We here note that the use of water sensors in STEM gameful learning is an area which has not received a lot of attention in the previous years. The IoT water sensing and related scenaria and practices, addressing children via discovery, gamification, and educational activities, are discussed in detail

OPTYMALIZACJA PROCESÓW ZARZĄDZANIA BUDYNKAMI KOMERCYJNYMI Z WYKORZYSTANIEM SYSTEMÓW ANALIZY ZACHOWAŃ UŻYTKOWNIKÓW WSPOMAGANYCH INTELIGENCJĄ OBLICZENIOWĄ I RTI

The aim of the presented project was to create a comprehensive building management system equipped with a network of wireless and energy-efficient sensors that collect data about users and on their basis control final devices such as lighting, ventilation, air conditioning and heating. In the presented system, end devices can be both products offered by the market (commercial) and proprietary solutions (own). This is to allow the adaptation of commercial radio communication protocols with high integration capabilities and common occurrence. In addition, the system has been enriched with an innovative system of tracking and building navigation and access control, which are supported by a network of radio beacons and radio-tomographic imaging technology (RTI). The whole system is to be supervised by computational intelligence learned from scratch.Celem prezentowanego projektu było stworzenie kompleksowego systemu zarządzania budynkiem wyposażonego w sieć bezprzewodowych i energooszczędnych czujników, które zbierają dane o użytkownikach i na ich podstawie sterują urządzeniami końcowymi, takimi jak oświetlenie, wentylacja, klimatyzacja i ogrzewanie. W prezentowanym systemie urządzeniami końcowymi mogą być zarówno produkty oferowane przez rynek (komercyjne), jak i rozwiązania autorskie (własne). Ma to na celu umożliwienie adaptacji komercyjnych protokołów komunikacji radiowej o dużych możliwościach integracyjnych i powszechnym występowaniu. Dodatkowo system został wzbogacony o innowacyjny system śledzenia i nawigacji po budynkach oraz kontroli dostępu, które są wspomagane przez sieć radiolatarni oraz technologię obrazowania radiowo-tomograficznego (RTI). Nad całością systemu ma czuwać inteligencja obliczeniowa wyuczona od podstaw
