Named Data Networking in IoT based sensor devices

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 general overview, the state of art, of the IoT world and of sensors networks, checking its potential and any restrictions, if present. Then, every engineering aspect of the realized project, will been described in detail. This thesis will also prove that nowadays we have the right items and components for the realization of reliable low-cost sensors. The ultimate purpose is to verify the introduction of new network protocols like NDN (Named Data Networking) to evaluate their performances and efficiency. Finally I will propose the simulations output obtained by NS3 (Network Simulator): a scenario simulation using NDNSim and ChronoSync application will be present

Development of an On-line Radiation Detection and Measurements Laboratory Course

An on-line radiation detection and measurements lab is being developed with a grant from the U.S. Nuclear Regulatory Commission. The on-line laboratory experiments are designed to provide a realistic laboratory experience and will be offered to students at colleges/universities where such a course is not offered. This thesis presents four web-based experiments: 1) nuclear electronics, 2) gamma-ray spectroscopy with scintillation detectors, 3) external gamma-ray dosimetry and gamma attenuation in matter, and 4) alpha spectroscopy and absorption in matter. The students access the experiments through a broad-band internet connection. Computer-controlled instrumentation developed in National Instruments (NI) LabVIEWTM communicates with the URSA-II (SE International, Inc.) data acquisition system, which controls the detector bias voltage, pulse shaping, amplifier gain, and ADC. Detector and amplifier output pulses can be displayed with other instrumentation developed in LabVIEWTM for the digital oscilloscope (USB-5132, NI). Additional instrumentation developed in LabVIEWTM is used to control the positions of all sources with stepper motor controllers (VXM-1, Velmex, Inc.) and adjust pressure in the alpha chamber with a digital vacuum regulator (DVR-200, J-KEM, Inc.). Unique interactive interfaces are created by integrating all of the necessary instrumentation to conduct each lab. These interfaces provide students with seamless functionality for data acquisition control, experimental control, and live data display with real-time updates for each experiment. A webcam is set up to stream the experiment live so the student can observe the physical instruments and receive visual feedback from the system in real time

Wireless Audio Interactive Knot

Thesis (S.M.)--Massachusetts Institute of Technology, School of Architecture and Planning, Program in Media Arts and Sciences, 2001.Includes bibliographical references (leaves 44-45).The Sound Transformer is a new type of musical instrument. It looks a little like a saxophone, but when you sing or "kazoo" into it, astonishing transforms and mutations come out. What actually happens is that the input sound is sent via 802.11 wireless link to a net server that transforms the sound and sends it back to the instrument's speaker. In other words, instead of a resonant acoustic body, or a local computer synthesizer, this architecture allows sound to be sourced or transformed by an infinite array of online services, and channeled through a gesturally expressive handheld. Emerging infrastructures (802.11, Bluetooth, 3G and 4G, etc) seem to aim at this new class of instrument. But can such an architecture really work? In particular, given the delays incurred by decoupling the sound transformation from the instrument over a wireless network, are interactive music applications feasible? My thesis is that they are. To prove this, I built a platform called WAI-KNOT (for Wireless Audio Interactive Knot) in order to examine the latency issues as well as other design elements, and test their viability and impact on real music making. The Sound Transformer is a WAI-KNOT application.Adam Douglas Smith.S.M

Icarus : aerial recording system

The goal of Project ICARUS is to create an aerial videography system that is easy to set up, inexpensive, portable, and highly adaptable to any situation. This is accomplished by using a balloon mounted camera rig that is grounded by a number of winches. This system is able to obtain a higher altitude than similar systems and is much more cost effective because the system can be applied to a number of circumstances such as sporting events, disaster relief, wildlife videography, and aerial monitoring, to name a few. The ICARUS system allows the user to control the position of an aerial camera as well as its orientation in three dimensional space using minimal infrastructure. This system features a control system that allows the user to specify an input in cartesian space as well as a live view from the aerial camera

Experimental Evaluation of a LoRa Wildlife Monitoring Network in a Forest Vegetation Area

Smart agriculture and wildlife monitoring are one of the recent trends of Internet of Things (IoT) applications, which are evolving in providing sustainable solutions from producers. This article details the design, development and assessment of a wildlife monitoring application for IoT animal repelling devices that is able to cover large areas, thanks to the low power wide area networks (LPWAN), which bridge the gap between cellular technologies and short range wireless technologies. LoRa, the global de-facto LPWAN, continues to attract attention given its open specification and ready availability of off-the-shelf hardware, with claims of several kilometers of range in harsh challenging environments. At first, this article presents a survey of the LPWAN for smart agriculture applications. We proceed to evaluate the performance of LoRa transmission technology operating in the 433 MHz and 868 MHz bands, aimed at wildlife monitoring in a forest vegetation area. To characterize the communication link, we mainly use the signal-to-noise ratio (SNR), received signal strength indicator (RSSI) and packet delivery ratio (PDR). Findings from this study show that achievable performance can greatly vary between the 433 MHz and 868 MHz bands, and prompt caution is required when taking numbers at face value, as this can have implications for IoT applications. In addition, our results show that the link reaches up to 860 m in the highly dense forest vegetation environment, while in the not so dense forest vegetation environment, it reaches up to 2050 m

This research is a literature study with a qualitative approach using descriptive-analytic analysis. The research results show that mobile learning as a subset of e-learning has many advantages in facilitating learning process without the limits of time, space and place. Although it has limitations, but mobile learning has a very good opportunity to be utilized on virtual learning during the covid-19 pandemic as an alternative to learning face to face. Tablets, smartphones and laptops can be used as supporting devices in the implementation of mobile learning. In order to be implemented optimally, teacher skills are needed in operating the device and designing teaching materials properly digitally based

Wireless Sensor System for Recycling

The motivation of this thesis was to research and design a prototype model of a wireless sensor network application, to be used as an automated detection infrastructure in recycling environment. The initial idea was to measure the level of the surface in a recycling container and transmit the information through a wireless communication system. The prototype is an initial step for recycling companies for building an automated detection network. Background of the research strongly supports the accomplished prototype. Study includes description of wireless environment with its problems and challenges. It proceeds with consideration of suitable wireless standards and considers most convenient sensor methods for recycling environment. Eventually document presents the prototype combining the studied entities. As a result, the prototype has two main operating parts: the wireless communication network and sensors. The network was realized with ZigBee standard by using two radio chips as communication nodes. Second communication node is attached to a recycling container and combined with two ultrasound sensors. This node includes a soft-ware algorithm, which is polling the state of the sensors regularly and deciding if the container is full. The node proceeds to transmission of the information to other communication node. This node is connected to computer and will transmit the information to be used by the recycling organization.fi=Opinnäytetyö kokotekstinä PDF-muodossa.|en=Thesis fulltext in PDF format.|sv=Lärdomsprov tillgängligt som fulltext i PDF-format
