  • Cache-aware routing in Information-Centric Networks 

    Sourlas, V.; Flegkas, P.; Tassiulas, L. (2013)
    Information-Centric Networking (ICN) has attracted the attention of the research community, which has argued that content, instead of end-points, must be at the center stage of attention. The research issues addressed by ...
  • Caching in content-based publish/subscribe systems 

    Sourlas, V.; Paschos, G. S.; Flegkas, P.; Tassiulas, L. (2009)
    In a publish/subscribe network, message delivery is guaranteed for all active subscribers at publish time. However, in a dynamic scenario where users join and leave the network, a user may be interested in content published ...
  • Content Replication and Delivery in Information-Centric Networks 

    Sourlas, V.; Flegkas, P.; Katsaros, D.; Tassiulas, L. (2014)
    Information-centric networking (ICN) is emerging as the main future networking environment, given that the vast majority of Internet activities are related to information access and delivery. This chapter presents a ...
  • A content-based publish/subscribe framework for large-scale content delivery 

    Diallo, M.; Sourlas, V.; Flegkas, P.; Fdida, S.; Tassiulas, L. (2013)
    The publish/subscribe communication paradigm has become an important architectural style for designing distributed systems and has recently been considered one of the most promising future network architectures that solves ...
  • Distribute, store and retrieve management policies in wireless ad-hoc networks using the content delivery publish/subscribe paradigm 

    Sourlas, V.; Flegkas, P.; Paschos, G. S.; Tassiulas, L. (2009)
    Policy management is a management paradigm that has been extensively studied for the case of fixed networks but limited work can be found for migrating it to mobile environments. It enables dynamic adaptation of the network ...
  • Distributed cache management in information-centric networks 

    Sourlas, V.; Gkatzikis, L.; Flegkas, P.; Tassiulas, L. (2013)
    The main promise of current research efforts in the area of Information-Centric Networking (ICN) architectures is to optimize the dissemination of information within transient communication relationships of endpoints. ...
  • Leveraging caching for internet-scale content-based publish/subscribe networks 

    Diallo, M.; Fdida, S.; Sourlas, V.; Flegkas, P.; Tassiulas, L. (2011)
    This work is concerned with scaling decentralized content-based publish/subscribe (CBPS) networks for Internet-wide content distribution. A fundamental step for CBPS networks to reach the Internet-scale is to move from the ...
  • Managing the Future Internet through Intelligent In-Network Substrates 

    Charalambides, M.; Pavlou, G.; Flegkas, P.; Wang, N.; Tuncer, D. (2011)
    The current Internet has been founded on the architectural premise of a simple network service used to interconnect relatively intelligent end systems. While this simplicity allowed it to reach an impressive scale, the ...
  • Mobility support through caching in content-based publish/subscribe networks 

    Sourlas, V.; Paschos, G. S.; Flegkas, P.; Tassiulas, L. (2010)
    In a publish/subscribe (pub/sub) network, message delivery is guaranteed for all connected subscribers at publish time. However, in a dynamic mobile scenario where users join and leave the network, it is important that ...
  • Mobility work re-visited not considered harmful 

    Trossen, D.; Vasilakos, X.; Flegkas, P.; Sourlas, V.; Parisis, G. (2011)
    The Internet is a universal source of information for its users. However, obtaining desired content has become the main focus of interest rather than the communication with machine endpoints. The increased availability of ...
  • Modeling the dynamics of caching in content-based publish/subscribe systems 

    Sourlas, V.; Paschos, G. S.; Mannersalo, P.; Flegkas, P.; Tassiulas, L. (2011)
    This paper considers cache dimensioning in the context of publish/subscribe (pub/sub) systems. We assume that each broker is equipped with a limited capacity cache and it decides upon a policy for caching and prioritizing ...
  • A novel cache aware routing scheme for Information-Centric Networks 

    Sourlas, V.; Flegkas, P.; Tassiulas, L. (2014)
    Information-Centric Networking (ICN) has attracted the attention of the research community, which has argued that content, instead of end-points, must be at the center stage of attention. The research issues addressed by ...
  • On exploiting network coding in cache-capable small-cell networks 

    Poularakis, K.; Sourlas, V.; Flegkas, P.; Tassiulas, L. (2014)
    Recently, network coding has emerged as an effective way to increase the efficiency of the content placement in the caching networks and thus boost the content delivery to the requesters. Its superiority compared to network ...
