  1. 1. Context-Based Authentication and Lightweight Group Key Establishment Protocol for IoT Devices

    University essay from Mittuniversitetet/Institutionen för informationssystem och –teknologi

    Author : Nico Ferrari; [2019]
    Keywords : Internet of Things; Context-based authentication; Fuzzy commitment scheme; Cryptographic key establishment; Lightweight cryptography; Contiki; One-way accumulators;

    Abstract : The concept of the Internet of Things is driven by advancements of the Internet with the interconnection of heterogeneous smart objects using different networking and communication technologies. With the rapidly increasing number of interconnected devices present in the life of a person, providing authentication and secure communication between them is considered a key challenge. READ MORE

  2. 2. Efficient Energy Use of FPGA for Underwater Sensor Network

    University essay from Linköpings universitet/Elektroniska Kretsar och System; Linköpings universitet/Elektroniska Kretsar och System

    Author : Erik Amgård; Kevin Bergman; [2019]
    Keywords : Underwater Sensor Network; FPGA; FFT; VHDL;

    Abstract : Operational time is becoming an increasingly important aspect in electronic devices and is also highly relevant in Underwater Acoustic Sensor Networks (UWSN). This thesis contains a study which explores what can be done to de-crease power consumption while maintaining the same functionality of an FPGA inside an underwater sensor-node network. READ MORE

  3. 3. Topology optimization for distributed consensus in multi-agent networks

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

    Author : Johan Niklasson; Oskar Hahr; [2019]
    Keywords : Multi-agent networks; Distributed systems; Wireless Sensor Network; Consensus averaging; Unmanned Aerial Vehicle; Graph-Theory.; Multiagent-nätverk; Distribuerade system; Trådlösa sensornätverk; Konsensusvärde; Drönare; Grafteori.;

    Abstract : Distributed networks, meaning a network in which several agents work together unanimously to perform some task in order to reach goals has become a field with a wide range of applications. One such applications may exist in the form of drones with a purpose of observing and detecting forest fires. READ MORE

  4. 4. Spatially Coupled Codes in Turbo Equalization

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

    Author : Mgeni Makambi Mashauri; [2019]
    Keywords : Turbo equalization; spatial coupling; waterfall versus error floor; codes on graphs; iterative receivers; LDPC codes in turbo equalization; Technology and Engineering;

    Abstract : In this thesis we investigate the application of spatial coupling in turbo equalization. We show that with spatial coupling we can have a fresh perspective on the trade-off between performance in the waterfall and error floor region often encountered in the choice of codes for turbo equalization.

  5. 5. A Machine Learning Approach to Predictively Determine Filter Clogging in a Ballast Water Treatment System

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Kristoffer Sliwinski; [2019]
    Keywords : ;

    Abstract : Since the introduction of the Ballast Water Management Convention, ballast water treatment systems are required to be used on ships for processing the ballast water to avoid spreading bacteria or other microbes which can destroy foreign ecosystems. One way of pre-processing the water for treatment is by straining the water through a filtration unit. READ MORE
