    • Asymptotic laws for content replication and delivery in wireless networks 

      Gitzenis, S.; Paschos, G. S.; Tassiulas, L. (2012)
      A key consideration in novel communication paradigms in multihop wireless networks regards the scalability of the network. We investigate the case of nodes making random requests on content stored in multiple replicas over ...

    • Caching and operator cooperation policies for layered video content delivery 

      Poularakis K., Iosifidis G., Argyriou A., Koutsopoulos I., Tassiulas L. (2016)
      Distributed caching architectures have been proposed for bringing content close to requesters and the key problem is to design caching algorithms for reducing content delivery delay. The problem obtains an interesting new ...

    • Optimal algorithms for hierarchical web caches 

      Poularakis, K.; Tassiulas, L. (2013)
      Hierarchical topologies have been applied in many existing systems that provide public IPTV or massive content delivery services. The efficient operation of these services requires massive bandwidth resources. Data caching ...

    • Optimal cooperative content placement algorithms in hierarchical cache topologies 

      Poularakis, K.; Tassiulas, L. (2012)
      The tremendous growth in the use of the World Wide Web and the expansion of Video On Demand and IPTV services increase the bandwidth demands, enforcing the creation of congestion in Internet's links and the experience of ...
