• A distributed data allocation scheme for autonomous nodes 

      Kolomvatsos K., Oikonomou P., Koziri M., Loukopoulos T. (2018)
      The limited computational and storage capabilities of the devices interconnected in Internet of Things (IoT) make them to host only a sub-set of the the collected data. Every device, i.e., an IoT node, should keep only the ...
    • Enabling mobile sensing through a DTN framework 

      Maglogiannis, V.; Kazdaridis, G.; Stavropoulos, D.; Korakis, T.; Tassiulas, L. (2013)
      Participatory Sensing is the concept of distributed data collection by self-selected participants. By exploiting latest technology's smart devices, a large number of valuable information can be collected through embedded ...
    • Formal model and scheduling heuristics for the replica migration problem 

      Tziritas, N.; Loukopoulos, T.; Lampsas, P.; Lalis, S. (2008)
      Replication of the most popular objects is often used in distributed data provision systems to reduce access time and improve availability. In fact, a given replica placement scheme may have to be redefined as object ...
