Predictive pumping based on sensor data and weather forecast
2019
In energy production, peat extraction has a significant role in Finland. However, protection of nature has become more and more important globally. How do we solve this conflict of interests respecting both views? In peat production, one important phase is to drain peat bog so that peat production becomes available. This means that we have control over how we can lead water away from peat bog to nature without water contamination with solid and other harmful substances. In this paper we describe a novel method how fouling of water bodies from peat bog can be controlled more efficiently by using weather forecast to predict rainfall and thus, minimize the effluents to nature. peerReviewed
Retrieving Monitoring and Accounting Information from Constrained Devices in Internet-of-Things Applications
2013
Part 6: Monitoring Mechanisms; International audience; Internet-of-Things (IoT) is envisioned to provide connectivity to a vast number of sensing or actuating devices with limited computational and communication capabilities. For the organizations that manage these constrained devices, the monitoring of each device’s operational status and performance level as well as the accounting of their resource usage are of great importance. However, monitoring and accounting support is lacking in today’s IoT platforms. Hence, this paper studies the applicability of the Constrained Application Protocol (CoAP), a lightweight transfer protocol under development by IETF, for efficiently retrieving monito…
Teollisen internetin hyödyntäminen toiminnanohjauksessa
2016
Teollinen internet on ollut informaatioteknologiatutkimuksen yksi ajankohtaisimmista aiheista. Yritysmaailmassa asiakkaat sekä toimittajat ovat todella kiinnostuneita teollisen internetin mahdollisuuksista. Teollista internetiä onkin pidetty mahdollisena seuraavana digitaalisena vallankumouksena. Palvelujen toiminnanohjauksessa ja yleisesti toiminnanohjauksessa on tapahtunut viimeisimpinä vuosina vain vähäisiä muutoksia, mutta nyt teollisen internetin odotetaan mullistavan jopa perinteiset toiminnanohjauksenjärjestelmät ja -prosessit. Yritykset niin teollisen internetin että toiminnanohjauksen alueilla ovat todella kiinnostuneita näiden kahden palasen yhdistämisestä ja sen tuomista mahdolli…
Compression Methods for Microclimate Data Based on Linear Approximation of Sensor Data
2019
Edge computing is currently one of the main research topics in the field of Internet of Things. Edge computing requires lightweight and computationally simple algorithms for sensor data analytics. Sensing edge devices are often battery powered and have a wireless connection. In designing edge devices the energy efficiency needs to be taken into account. Pre-processing the data locally in the edge device reduces the amount of data and thus decreases the energy consumption of wireless data transmission. Sensor data compression algorithms presented in this paper are mainly based on data linearity. Microclimate data is near linear in short time window and thus simple linear approximation based …
Kyberturvallisuus esineiden internetissä
2017
Esineiden internetin laitteiden määrä on jatkuvasti kasvussa ja niiden hyödyt koskettavat kaikkia yhteiskuntamme jäseniä. Valitettavasti samanaikaisesti myös onnistuneiden kyberhyökkäysten määrä on kasvussa ja se uhkaa esineiden inter-netin luotettavuutta. Tämän takia onkin tärkeää tutkia, minkälaisia uhkia esinei-den internet kohtaa ja kuinka näiltä uhkilta voitaisiin suojautua. Tutkielmassa käsitellään esineiden internetin laitteita, mitä kyseiset laitteet ovat, kuinka ne toi-mivat ja miten ne ovat suojattu. Tutkielma toteutettiin kirjallisuuskatsauksena ja sen lähteinä on käytetty pääsääntöisesti akateemisten julkaisujen artikkeleita. Tutkielmassa selvisi esineiden internetin kyberturval…
A gap analysis of Internet-of-Things platforms
2016
We are experiencing an abundance of Internet-of-Things (IoT) middleware solutions that provide connectivity for sensors and actuators to the Internet. To gain a widespread adoption, these middleware solutions, referred to as platforms, have to meet the expectations of different players in the IoT ecosystem, including device providers, application developers, and end-users, among others. In this article, we evaluate a representative sample of these platforms, both proprietary and open-source, on the basis of their ability to meet the expectations of different IoT users. The evaluation is thus more focused on how ready and usable these platforms are for IoT ecosystem players, rather than on t…
Internet of Things for Sustainable Smart Education: An Overview
2022
In the realm of fourth-generation industrialization, there will be great demand for a skilled workforceTo produce a skilled workforce, we need sustainable education with quality and equity. Conventional ways of delivering and managing education would not fulfil the demands of the fourth industrial revolution (4IR). Disruptive technologies, such as Internet of Things (IoT), have great potential in revolutionizing the current educational setup. Therefore, this research work aims to present an overview of the capabilities of IoT applications in educational settings. Our research article digs into recent research carried out referring to IoT applications in education and provides a detailed ins…

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 …
HALE-IoT: HArdening LEgacy Internet-of-Things devices by retrofitting defensive firmware modifications and implants
2022
Internet-Of-Things (IoT) devices and their firmware are notorious for their lifelong vulnerabilities. As device infection increases, vendors also fail to release patches at a competitive pace. Despite security in IoT being an active area of research, prior work has mainly focused on vulnerability detection and exploitation, threat modelling, and protocol security. However, these methods are ineffective in preventing attacks against legacy and End-Of-Life devices that are already vulnerable. Current research mainly focuses on implementing and demonstrating the potential of malicious modifications. Hardening emerges as an effective solution to provide IoT devices with an additional layer of d…
