  1. 1. Consensus Algorithm with Input Constraints and Collision Avoidance for Swarming Sunshade Satellites near the L1 point

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Felicia Törning; [2022]
    Keywords : Consensus algorithm; Formation control; Multi agent system; Solar sailing; Space based geoengineering; Konsensusalgoritm; Formationskontroll; multiagent system; solsegel;

    Abstract : Swarm Control Theory studies how multi-agent systems interact to solve tasks cooperatively. In this thesis it was studied how graph theory and the Dynamic Average Consensus Algorithm can be used to control swarming sunshade satellites near L1 for global temperature control, and if it would be suitable for the purpose.

  3. 2. Simulating Distributed Executions in Kompact

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

    Author : Johan Mallo Bakken; [2022]
    Keywords : Simulation; Testing; Distributed Systems; Kompact; Liveness; Raft; Simulering; Testning; Distribuerade System; Kompact; Liveness; Raft;

    Abstract : Distributed systems are complex systems that offer highly scalable and reliable services. With that complexity comes the difficulty of developing and testing such systems as they are highly non-deterministic. READ MORE

  4. 3. BGPcredit : A Blockchain-based System for Securing BGP

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

    Author : Yu Yang Liu; [2022]
    Keywords : blockchain; RPKI; consensus algorithm; border gateway protocol; security; blockchain; RPKI; konsensusalgoritm; border gateway-protokoll; säkerhet;

    Abstract : Due to the absence of appropriate security mechanisms, even the latest version of Board Gateway Protocol (BGP) is still highly vulnerable to malicious routing hijacking. The original problem is that BGP allows router to accept any BGP update message without any extra validation process. READ MORE

  5. 4. Consensus algorithms for adding blocks to private blockchains in IIoT networks : Comparison of two Proof-of-Authentication implementations on IIoT hardware

    University essay from KTH/Hälsoinformatik och logistik

    Author : Kamile Juvencius; Therése Ankarberg; [2021]
    Keywords : IoT; IIoT; blockchain; consensus algorithms; Proof-of-Authentication; CloudRail; IoT; IIoT; blockkedja; konsensusalgoritmer; Proof-of-Authentication; CloudRail;

    Abstract : The Internet of Things (IoT) market is growing by the day and there are no signs of stagnation. As the market grows, it becomes all the more important to address security concerns. A major security issue of IoT is that the devices usually send their collected data to a centralized entity, creating a single point of failure. READ MORE

  6. 5. A study on solutions of cross-ledger intercommunication : Classification, analysis and comparison of crosschain projects

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

    Author : Yuan Fan; [2020]
    Keywords : Distributed Ledger Technology; Cross-chain study; Atomic swaps; Interledger protocol; Relay; Sidechains; Distribuerad Huvudboksteknik; Tvärkedjestudie; Atombyte; Interledger-protokoll; Relä; Sidokedjor;

    Abstract : The phenomenon of isolated value in each blockchain system has become adistinct issue of the blockchain field. To address this problem, the demandof cross-chain intercommunication came up. In a narrow sense, cross-chainrefers to the process of asset interoperability between relatively independentblockchains.
