  1. 21. Energy harvesting from ambient WiFi energy : A method of harvesting and measuring ambient WiFi energy

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Alpha Fofana; Carl Mossberg; [2019]
    Keywords : Energy harvesting; Rectenna; Impedance matching; Embedded system; IoT; WiFi; Sustainable Energy; Utvinna energi; Impedansmatchning; Inbyggda system; IoT; WiFi; Hållbar utveckling;

    Abstract : The aim of this thesis was to investigate the question of how to harvest RF energy and if we can harvest enough RF energy for it to be useful in an application. It is aimed towards sensor node applications, commonly used in a typical office environment. The WiFi band was chosen since it is omnipresent in the same environment. READ MORE

  4. 23. Internet of things and implementation of local wireless sensor network

    University essay from

    Author : Anthon Jonsson; [2019]
    Keywords : ;

    Abstract : This master’s thesis covers the research and development of a local wireless sensor network with capabilities for IoT (internet of things) applications and with the ability to monitor and automatically control a watering system with soil humidity as input. The goal with this thesis was to develop a system where the wireless communication within the local network is suited for low power and lossy networks (LLN). READ MORE

  5. 24. Implementation of an Age of Information-aware Scheduler for Resource Constrained Devices

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Lukas Wirne; [2019]
    Keywords : ;

    Abstract : We examine a system where remote applications frequently request fresh information from sensor nodes through an edge and cloud based infrastructure. We study a scheduling policy that ensures fresh information while reducing energy consumption. In this work we build a testbed for evaluating the performance of the policy. READ MORE

  6. 25. Non-Coherent Radio-Based Positioning

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Farshid Rezaei; Mohamad Abou Nasa; [2019]
    Keywords : target localization and tracking; wireless sensor network WSN ; hybrid measurements; received signal strength RSS ; angle of arrival AoA ; Technology and Engineering;

    Abstract : In this thesis, a new Angle-of-Arrival (AoA) technique is used to determine the direction of a target in an outdoor environment using Radio Frequency (RF) signals. This technique estimates the AoA based on the difference between the Received Signal Strength Indicators (RSSI) from two/four directive antennas. READ MORE
