  1. 1. Implementation of LPWAN protocols for Water Sense : Integration of LoRa and Contiki OS with the Rime stack

    University essay from Uppsala universitet/Signaler och system

    Author : Barry Dyi; [2022]
    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

  3. 2. Energy Efficient Communication Scheduling for IoT-based Waterbirds Monitoring: Decentralized Strategies

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

    Author : Otabek Sobirov; [2022]
    Keywords : TSCH; 6TiSCH; RPL; scheduling; energy consumption; COOJA; autonomous scheduling; distributed scheduling; reinforcement learning; RL-based scheduling; Q-Learning;

    Abstract : Monitoring waterbirds have several benefits, including analyzing the number of endangered species, giving a reliable indication of public health, etc. Monitoring waterbirds in their habitat is a challenging task since the location is distant, and the collection of monitoring data requires large bandwidth.

  6. 5. Media Access Control for Wireless Sensor and Actuator Networks

    University essay from Kommunikationssystem; Tekniska högskolan

    Author : Muaz Un Nabi; [2012]
    Keywords : NS-2; WSN; IWLAN; DCF; PCF;

    Abstract : In a wireless network, the medium is a shared resource. The nodes in the network negotiate access of the shared resource using the Medium Access Control (MAC) protocol. The design of a MAC protocol for a sensor node is not the same as that for a wireless transceiver. READ MORE
