Experimental Analysis of IoT Networks Based on LoRa/LoRaWAN under Indoor and Outdoor EnvirMedusonments: Performance and Limitations
2021
Nowadays, Internet of Things (IoT) has multiple applications in different fields. This concept allows physical devices to connect to the internet in order to establish a strong infrastructure that facilitates many device control and monitoring tasks. Low Power Wide Area (LPWA) communication protocols become widely used for IoT networks because of their low power consumption and the broad range communication. LPWA enables devices to transmit small amounts of data in a long distance. Among LPWA protocols, LoRa technology gained a lot of interest recently from the research community and many companies. LoRa is a long range and low power wireless communication technology regulated by the LoRaWA…
Internet of Things : a gateway centric solution for providing IoT connectivity
2016
The Internet of Things (IoT) is revolutionising the traditional Internet by extending it with smart everyday objects. Wearables, smart grids and home automation systems are just a few examples of the IoT. A noteworthy point is that the amount of devices connected to the Internet will rapidly grow with the IoT. The IoT typically involves devices that are constrained in terms of energy, memory and processing resources. Therefore, they also limit applying the existing Internet protocols to the IoT. New protocols have been designed for the IoT, all the way from the physical layer, to the application layer. This thesis presents an implementation for an IoT gateway, which enables connectivity to …
Classification of Actual Sensor Network Deployments in Research Studies from 2013 to 2017
2020
Technologies, such as Wireless Sensor Networks (WSN) and Internet of Things (IoT), have captured the imagination of researchers, businesses, and general public, due to breakthroughs in embedded system development, sensing technologies, and ubiquitous connectivity in recent years. That resulted in the emergence of an enormous, difficult-to-navigate body of work related to WSN and IoT. In an ongoing research effort to highlight trends and developments in these technologies and to see whether they are actually deployed rather than subjects of theoretical research with presumed potential use cases, we gathered and codified a dataset of scientific publications from a five-year period from 2013 t…
Universally Designed Beacon-Assisted Indoor Navigation for Emergency Evacuations
2019
International audience; The United Nations (UN) Convention on the Rights of Persons with Disabilities (CRPD) obligates national governments to ensure the protection and safety of persons with disabilities in emergency situations. This article examines the application and accessibility of state-of-the-art ICT solutions in emergency situations. Research has indeed shown that the design and implementation of evacuation procedures in emergency situations play a critical role in ensuring personal safety and protection. While research has examined the experiences of persons including persons with disabilities in emergency situations, research has yet to examine fully the role that cutting-edge in…
The Adoption of The Internet of Things by Young Consumers – an Empirical Investigation
2017
On the background of theoretical considerations and literature review, this article presents the results of the preliminary study of young consumers about their adoption of the Internet of Things (IoT) - treated as the emerging technology, creating a new quality of information technology usage, despite perceived costs and privacy concerns. The data for the analysis came from purpose sample of 223 young consumers from Eastern Poland via CAWI questionnaire. The primary goal of the research was to explore the adoption of IoT by young consumers in Poland regarding the level of adoption and factors explaining this phenomenon. The main analysis used univariate analysis of variance (UNIANOVA) and …
LoRaWAN datu pārraides tīkla veiktspējas novērtējums Rīgas pilsētā un tās apkaimē
2018
Zemas enerģijas patēriņa, plaša pārklājuma datu pārraides tehnoloģijas (LPWAN) pēdējo gadu laikā arvien vairāk tiek izmantotas dažādu tautsaimniecības problēmu risināšanai. Paralēli noris aktīvi šo tehnoloģiju pētījumi un attīstība, kā arī meklēti praktiski tehnoloģiju pielietojumi lietu interneta (Internet of Things jeb IoT) vidē. Darba mērķis ir izpētīt zemas enerģijas patēriņa, liela pārklājuma bezvadu datu pārraides tehnoloģijas un to realizāciju ar LoRaWAN tehnoloģijas palīdzību. Papildu teorētiskajiem pētījumiem, darba mērķis ir praktiski pārbaudīt, vai LoRaWAN datu pārraides pārklājums atbilst dokumentācijā aprakstītajam, ka pilsētā tas var sasniegt līdz pat 8 km distanci. Darba prak…
Internet of Things : Wireless Technologies in Home Automation Solutions
2015
Esineiden internet on kasvava ala ja kotiautomaatioratkaisut ovat todennäköi-sesti kuluttajien ensimmäisiä kosketuksia tämänlaiseen teknologiaan. Radiotaa-juusteknologiat ovat olennainen osa sensoriverkkoa ja tällä hetkellä moni tek-nologia pyrkii olemaan standardi kotiautomaatiossa. Kotiautomaatio liiketoi-mintana tulee kasvamaan voimakkaasti tulevina vuosina ja kehittyneillä senso-riverkoilla pelkästään kotona mahdollisuudet ovat suuret. Tässä tutkielmassa esitellään neljä teknologiaa: Wi-Fi, ZigBee, Z-wave ja Bluetooth. Teknologioiden pääpiirteet on selitetty ja esitetty olemassa olevien tuotteiden kautta. Olen käyttänyt SWOT–analyysiä tuotteisiin ja niitä tuottaviin yrityksiin saadaksen…
Releasing upper Lapland : Martin Heidegger and the question concerning nature
2008
This study is a phenomenological-hermeneutical analysis of the Upper Lapland forest conflict. Reindeer husbandry, state forestry and nature-based tourism are the main sources of livelihood in Upper Lapland. Also large, state-owned wilderness areas have been reserved for nature conservation. Utilisation of the forests and wilderness areas for different purposes has lead to a situation where the livelihoods are forced to compete with each other and conflicts between the different interest groups have arisen during recent years. The theoretical background of the study is Martin Heidegger’s critique of technology and his idea of Releasement (Gelassenheit). He was concerned with technology, not …
Dynamic Ordering of Firewall Rules Using a Novel Swapping Window-based Paradigm
2016
Designing and implementing efficient firewall strategies in the age of the Internet of Things (IoT) is far from trivial. This is because, as time proceeds, an increasing number of devices will be connected, accessed and controlled on the Internet. Additionally, an ever-increasingly amount of sensitive information will be stored on various networks. A good and effi- cient firewall strategy will attempt to secure this information, and to also manage the large amount of inevitable network traffic that these devices create. The goal of this paper is to propose a framework for designing optimized firewalls for the IoT. This paper deals with two fundamental challenges/problems encountered in such…
La natura delle cose
2022
The reference to the nature of things is still working today in legislation and jurisprudence. In this article the reasons for the persistence of this line of reasoning in law and in the legal science are examined. These reasons generally depend on the close connection between law and some fundamental social relations. But also the essential need to assure its effectiveness, without which law would be useless. In turn, the contemporary evolution of the legal culture requires a change in the way of understanding the nature of things. Nowadays, the nature of things distances itself from mere objectivism to get close to the deliberative character of the determination of the law
