Abstract:

In a world running on a “smart” vision, the Internet of Things (IoT) progress is going faster than ever. The term “things” is not just about computer, people and smartphone, but also sensors, refrigerators, vehicles, clothing, food and so on. Internet of Things is the possibility to provide an IP address for every item, so it will have an interface on the Internet network. The household devices will not just being commanded and monitored remotely then, but they will have an active main character role, establishing a communication network between them. The thesis will begin describing a gene

Abstract:

The IoT is in a continuous evolution thanks to new technologies that open the doors to various applications. While the structure of the IoT network remains the same over the years, specifically composed of a server, gateways, and nodes, their tasks change according to new challenges: the use of multimedia information and the large amount of data created by millions of devices forces the system to move from the cloud-centric approach to the thing-centric approach, where nodes partially process the information. Computing at the sensor node level solves well-known problems like scalability

Abstract:

IoT devices are increasingly used in the process of gathering scientific data. In environmental monitoring IoT devices can be used as remote sensing devices to collect information about e.g. temperature. To keep data reliable, various security aspects have to be considered. Constrained devices are limited by memory size and battery life, a security solution has to be developed with this in mind. In this study an IoT security solution was developed in collaboration with a research group in environmental science at Umeå University. We selected commonly used algorithms and compare

Abstract:

Robust ion-exchanged glass waveguides exhibit low optical losses in a broad spectral range and they allow integration of several devices on the same chip due to their planar structure. Consequently, they can be a low cost alternative to semiconductors for fabricating various integrated optical devices. Two high performance photonic devices were designed and realized, demonstrating the potential of glass waveguides. The well-controlled silver-film ion-exchange process allowed the fabrication of: i) a highly sensitive biosensor based on optical absorption and, ii) a low loss hybrid electro-opt

Traditionally, ETSU maintenance operate on daily routes to pick trash on designated time, regardless the level of the containers.

This overflown trashcan result in an unclean environment for the community and an unpleasant look of our beautiful campus.

The Internet of things is a scenario where devices such as lighting, household appliances, sensors etc. are connected and communicate with each other via Internet. This puts a demand for a good infrastructure around these devices. One way to handle this is to use radio as a means of communication and let the devices forward each other's traffic in what is known as a mesh network. This thesis explores different radio standards that can be used to create a mesh network for sensors.

Point-of-care (POC) diagnostics presents a giant market opportunity with profound societal impact. In particular, specific detection of DNA and protein markers can be essential for early diagnosis of e.g. cancer, cardiovascular disease, infections or allergies. Today, identification of these markers often requires extensive laboratory work and hence is expensive and time consuming. Current methods for recognition and detection of specific biomolecules are mostly optics based and thus impose severe limitations as to convenience, specificity, sensitivity, parallel processing and cost reduction.

Abstract:

This report presents a project carried out for the company Cybercom by eight students from Linköping University. The aim of the project has been to develop a real-time multiplayer game using an existing system for communication between different devices. The game has been developed as a web app that contains multiple game modes. The specific development methodology that has been used throughout the project is presented in this report. This methodology has been iterative, agile and followed a simplified version of the Scrum framework. The end result of the project is a well functioning product

Abstract:

Wireless sensor networks used in smart cities and elsewhere collect large amounts of sensor data that needs to be made available to respective audiences and have proper visualization. There is a lack of mobile applications capable of visualizing sensor data coming from multiple sources using different protocols and data formats in a clear way; an application that is easy for anyone to use. This paper will present the development and evaluation of Smart City IoT which is an Android application for visualization of IoT data collected from wireless sensor networks. The resulting application Smart

Abstract:

Background. The rapid growth of IoT devices in homes put people at risk of cyberattacks and the low power and computing capabilities in IoT devices make it difficultto design a security solution for them. One method of preventing cyber attacks isan Intrusion Detection System (IDS) that can identify incoming attacks so that anappropriate action can be taken. Previous attempts have been made using machinelearning and deep learning however these attempts have struggled at detecting newattacks.Objectives. In this work we use a convolutional neural network IoTNet designed forIoT devices to classify

This paper will explore the speed of execution, memory foot-print and the maturity of WebAssembly Runtimes (WasmRT).For this study, the WasmRT will be Wasmer1and Wasmtime.2Initially, benchmarks were run on a Raspberry Pi 3 model Bto simulate a more hardware capable IoT-device. Tests per-formed on a Raspberry Pi shows that there are many instanceswhere a WasmRT outperforms a similar Docker+C solution.WasmRT has a very clear use case for IoT devices, specifi-cally short jobs, the results from our research will show thatWasmRT can be up to almost 70 times as fast as a similarDocker solution.

Abstract:

Internet of Things (IoT) is a network of devices that are connected through the Internet to exchange the data for intelligent applications. Though IoT devices provide several advantages to improve the quality of life, they also present challenges related to security. The security issues related to IoT devices include leakage of information through Differential Power Analysis (DPA) based side channel attacks, authentication, piracy, etc. DPA is a type of side-channel attack where the attacker monitors the power consumption of the device to guess the secret key stored in it. There are several co

Abstract:

The increasing use of smart devices for monitoring spaces has caused an increase in concerns about the privacy of users of these spaces. Given this problem, the legislation on the right to privacy has been worked to ensure that the existing laws on this subject are sufficiently comprehensive to preserve the privacy of users. In this way, research on this topic evolves in the sense of creating systems that ensure compliance with these laws, that is, increase transparency in the treatment of user data. In the context of this dissertation, a demonstrator-based strategy is presented to prov
