  3. 12. Reliable UDP and Circular DHT implementation for the MediaSense Open-Source Platform

    University essay from Institutionen för informationsteknologi och medier

    Author : Timo Schröder; Florian Rüter; [2012]
    Keywords : Internet-of-Things; MediaSense; Peer-to-peer; Chord; Distribut Hash Table; Networking; Reliable UDP; Simulation;

    Abstract : MediaSense is an EU funded platform that is an implementation of an Internet-of-Things framework. This project adds two fundamental functions to it, namely, a new lookup service based on a peer-to-peer Distributed Hash Table (DHT) called Chord and a reliable communication protocol based on UDP (RUDP).

  4. 13. Distributed Trust-Aware Recommender Systems

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Stefan Magureanu; [2012]
    Keywords : ;

    Abstract : Collaborative filtering(CF) recommender systems are among the most popular approaches to solving the information overload problem in social networks by generating accurate predictions based on the ratings of similar users. Traditional CF recommenders suffer from lack of scalability while decentralized CF recommenders (DHT based, gossip based etc. READ MORE

  5. 14. Persistence and Node FailureRecovery in Strongly Consistent Key-Value Datastore

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Muhammad Ehsan ul Haque; [2012]
    Keywords : Datastore; Distributed Hash Table DHT ; Atomic Shared Registers; Disk Storage; Consistency; Failure Recovery; Paxos; Group Membership;

    Abstract : Consistency preservation of replicated data is a critical aspect for distributed databaseswhich are strongly consistent. Further, in fail-recovery model each process also needs todeal with the management of stable storage and amnesia [1]. READ MORE

  6. 15. Decentralized Indexing of Presentities over n-Dimensional Context Information

    University essay from Institutionen för informationsteknologi och medier

    Author : Christian Lentfort; [2012]
    Keywords : context awareness; indexing; space-filling curves; Hilbert curve; Pastry; PAST;

    Abstract : Modern context-aware applications no longer justify their decisions based only on their own information but on the decisions and information of other applications in a similar context.  Acquiring context information of other entities in an distributed system is difficult task when using the current content centric solutions such as DHTs.
