Повний текст джерелаProjektet har innefattat att ta fram en GPS-spårsändare som kan läsa NFC (Near Field Communication)-taggar, kommunicera med LoRa (Long Range) och BLE (Bluetooth low energy) samt undersöka vilka av GPS-spårsändarens olika delar som konsumerar mest energi. Användningsområdet för GPS-spårsändaren är att effektivisera räddningsinsatser på skadeplatser där det finns skadade människor exempelvis efter en översvämning eller terroristattack. Effektiviseringen är tänkt ska ske genom att en operationsledare styr räddningsinsatsen med hjälp av informationen som skickas från GPS-spårsändarna som kommer att bäras av skadade personer och räddningspersonalen på skadeplatsen. GPS-spårsändaren är utvecklad kring sensorutvecklings kittet Thingy:52 från Nordic Semiconductor och dess mjukvara har utvecklats genom att modifiera den mjukvara som Nordic Semiconductor har utvecklat för Thingy:52. De delar av GPS-spårsändaren som visade sig konsumera mest energi var GPS-modulen och NFC-läsaren. I rapporten finns energioptimerings förslag för dessa delar. Rapporten innehåller även ett förslag till ett kretsschema för GPS-spårsändaren som kan användas vid framtida miniatyrisering av GPS-spårsändaren.

Повний текст джерелаThe progress in low-energy, low-cost communication technologies have revolutionized remote sensing and monitoring applications. Internet of Things (IoT) has promised an ecosystem of connected devices across a wide range of applications such as in smart cities.Currently, many competing standards and technologies are attempting to seize the IoT, particularly in the area of remote sensing and communication technologies. LoRa (Long Range) is one of those technologies that is gaining popularity and attraction in the Wireless Sensor Networks (WSN) applications. The ability to make long-distance communications with relatively simple nodes, minimal infrastructure, reduced power requirements, and the use of unlicensed ISM bands provides a significant competitive advantage. Although the communication range in LoRa can exceed 15 kilometers in line of sight, the maximum bit rate that can be achieved is limited to few kilobits per second. Additionally, when a collision occurs in LoRa, the throughput is further reduced due to frame losses and retransmissions. The work of this thesis deals with the problem of collisions in LoRa that may occur under heavy load, and which degrade the performance of the network.First, we consider the context for LoRaWAN uplink communications. We study the context of fully synchronized colliding LoRa signals, where each end-device has to retransmit its entire colliding frame after a collision occurs in LoRa. This behavior decreases the overall throughput, and increases the energy consumption of the end-devices, and the delay of the frames. Therefore, in order to mitigate the damaging effects of collisions, we proposed a decoding algorithm to resolve synchronized colliding LoRa signals, in a saturated and confirmed network traffic. We substituted the conventional retransmission model of LoRa by having end-devices transmitting bitmaps instead of retransmitting whole frames to determine the correct symbols of each colliding frame. Our algorithm was able to significantly improve the overall throughput of the LoRaWAN MAC layer based on LoRa, and to decrease the energy consumption of the transmitters and the delay of the frames.Second, we consider the context for LoRaWAN downlink communications. We noticed that the downlink in LoRa is a bottleneck. Hence, we worked on the gateway selection by the network server and its impact on the throughput, the energy consumption and the delay. We studied three types of gateway deployment and we show that the system performance depends on this deployment. We showed that balancing the number of end-devices per gateway (also known as load) improves the throughput compared to choosing the gateway with the highest signal quality. Moreover, we showed that combining load and signal quality does not further improve the throughput. In addition, we showed that choosing the gateway with the highest signal quality decreases the delay and energy consumption compared to choosing the gateway with the lowest load

Due to the long range capabilities and low energy consumption, Low-Power Wide Area Networks (LPWANs) are the ideal technologies to send small data occasionally. With their unique characteristics, LPWANs can be used in many applications and in di erent environments such as urban, rural and even indoor. The work developed in this dissertation presents a study on the LPWAN LoRa technology, by testing and evaluate its range, signal quality properties and its performance in delivering data. For this, three distinct scenarios are proposed and tested. The inclusion of LoRa in a multi-technology data gathering platform is the key objective of this dissertation. For this it is proposed: (1) an organization based in clusters of sensor nodes; (2) a Media Access Control (MAC) protocol to provide e cient communications through the LoRa technology; and nally, (3) a Connection Manager that is capable of managing the di erent available technologies in the sensor nodes and that is able to adapt its actions according to the acquired data type is proposed. The performed tests aim to perceive which type of parameters can in uence the performance of the overall proposed solution, as well as the advantages of a multi-technology approach in a data gathering platform.
Low-Power Wide Area Networks (LPWANs) são um conjunto de tecnologias em crescimento na área da Internet of Things (IoT). Devido ás suas capacidades de comunicar a longo alcance e de baixo consumo energético, as LPWANs apresentam-se como a tecnologia ideal para o envio ocasional de pequenas porções de dados. Ao possuírem características únicas, as LPWANs podem ser usadas em diversas aplicações e em diferentes ambientes, sejam eles urbanos, rurais ou interiores. O trabalho desenvolvido nesta dissertação apresenta um estudo acerca da tecnologia Long Range (LoRa), uma LPWAN, testando e avaliando o seu alcance, a qualidade do sinal e o desempenho na entrega de dados. Para isso, três cenários distintos são propostos e testados. A inclusão de LoRa numa plataforma de aquisição de dados com múltiplas tecnologias e um dos objectivos chave desta dissertação. Para isso, são propostas: (1) uma organização baseada em clusters de sensores; (2) um protocolo de controlo de acesso ao meio (MAC) para permitir que as comunicações através de LoRa sejam eficientes; e finalmente, (3) um gestor de conectividade com capacidade de gerir as diferentes tecnologias disponíveis nos sensores e que seja capaz de agir consoante o tipo de dados adquiridos. Os testes efectuados tem como objectivo perceber que tipo de parâmetros podem influenciar o desempenho global da soluçao proposta, bem como as vantagens de usar uma abordagem baseada em múltiplas tecnologias numa plataforma de aquisição de dados.

Повний текст джерелаDetecting noise levels explains a lot in urban areas such as noise levels, number of shots, and number of collisions. In this project, a sound detector is installed that communicates via LoRa, Long Range when the sound exceeds a threshold value. The sound detector is implemented as a stand-alone module consisting of three existing modules. The modules used in the project include Lopy4 with Expansion Card 3.1, GPS module, and Sound sensor. The sound level, battery level, coordinates, date, and time are transferred via LoRa to a gateway and on to The Thing of Network, TTN website, and at the same time data is saved locally in an SD memory card when the sound exceeds a threshold. The threshold can be modified according to the user's wishes.

Повний текст джерелаThis thesis is part of the concept of the Internet of Things (IoT), object identification, and traceability in so-called complex environments through Ultra-Wide Band (UWB) technology known for its high temporal precision. The objective is to contribute to the advancement of real-time UWB-based localization systems through the design and optimization of UWB antennas that are reconfigurable, multi-standards, and multi-functions. Therefore, any localization system integrating the optimized antennas will have improved localization quality and new functionalities.The main contributions developed in this thesis involve enhancements to real-time localization systems (RTLS) based on UWB technology: design and fabrication of frequency reconfigurable UWB antennas; design and fabrication of a multi-standard localization electronic board (UWB and Long Range - LoRa); experimental study of RTLS systems incorporating the designed antennas and validation of the evolution of the localization in terms of extended reading ranges, detectability of objects without prior knowledge of their orientations, and improved location accuracy through the attenuation of multi-path signals
