    Keywords : Contiki; LoRa; Telecommunications; Embedded Systems; WSN; IoT;

    Abstract : The purpose of this thesis rose from tackling a specific project led by Cybercom Group. Water Sense was proposed after municipalities expressed the need to conveniently conduct measurements on water in Swedish lakes, and remotely get access to these data. READ MORE

  5. 4. Detecting and identifying radio jamming attacks in low-power wireless sensor networks

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : John Kanwar; [2021]
    Keywords : ;

    Abstract : Wireless sensor networks (WSNs) are used in all kinds of different sectors ranging from agriculture, environment, healthcare and the military. Embedded systems such as sensor nodes are low-power and consist of low memory, which creates a challenge for its security. One of WSN’s worst enemies is interference radio jamming attacks. READ MORE

  6. 5. 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
