    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :HongShuo Yi; Duosi Dai; [2023]
    Nyckelord :LoRa; Indoor IoT Internet of Things ; Signal strength; Round-trip time RTT ; Goodput; LoRaWAN device classes; AVR-RSS2; RIOT-OS; LoRa; Inomhus-IoT Internet of Things ; Signalstyrka; Rundresa-tid RTT ; Goodput; LoRaWAN klasser; AVR-RSS2; RIOT-OS;

    Sammanfattning : This thesis is dedicated to measuring the communication performance of LoRa technology in an indoor environment and providing insight into its potential application as an effective Internet of Things (IoT) communication solution in Low Power Wide Area Networks (LPWAN). Through careful experimentation and analysis, we assessed various transmission parameters such as spreading factor (SF), bandwidth (BW), Payload Length (PL), and LoRaWAN classes. LÄS MER

  3. 2. Integration of Attribute-Based Encryption and IoT: An IoT Security Architecture

    Master-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

    Författare :Ziyad Elbanna; [2023]
    Nyckelord :Internet of things; Attribute based encryption; Fine-grained access control; Key revocation; Proxy re-encryption;

    Sammanfattning : Services relying on internet of things (IoTs) are increasing day by day. IoT makes use of internet services like network connectivity and computing capability to transform everyday objects into smart things that can interact with users, and the environment to achieve a purpose they are designed for.

  4. 3. Securing LwM2M with Mbed TLS in Contiki-NG

    Magister-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Jayendra Ellamathy; [2023]
    Nyckelord :;

    Sammanfattning : As the Internet of Things (IoT) becomes increasingly integrated into our personal lives and industries, security concerns and attacks on these devices are growing. This concern is one of the major bottlenecks for adopting IoT, as these devices can often collect sensitive information. LÄS MER

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

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Barry Dyi; [2022]
    Nyckelord :Contiki; LoRa; Telecommunications; Embedded Systems; WSN; IoT;

    Sammanfattning : 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. LÄS MER

  7. 5. Enhanced DTLS Support for the Contiki-NG OS

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)
