      Adaptive mixing control with multiple estimators 

      Baldi, S.; Ioannou, Petros A.; Kosmatopoulos, E. B. (2012)
      A recently proposed adaptive control scheme with mixing involves the use of precalculated candidate controllers whose output is weighted on the basis of the parameter estimates generated by an online parameter estimator. ...

      Analysis of probabilistic flooding in VANETs for optimal rebroadcast probabilities 

      Saeed, T.; Lestas, Marios; Mylonas, Yiannos; Pitsillides, Andreas; Lesta, Vicky Papadopoulou (Institute of Electrical and Electronics Engineers Inc., 2016)
      A number of probabilistic flooding schemes have been recently considered in VANETs to address problems of information dissemination in safety applications. The design approach has so far been simulative, a method which ...

      Evaluating the utility of content delivery networks 

      Stamos, Kostas; Vakali, Athena I.; Pallis, George C.; Dikaiakos, Marios D. (2009)
      Content Delivery Networks (CDNs) balance costs and quality in services related to content delivery. This has urged many Web entrepreneurs to make contracts with CDNs. In the literature, a wide range of techniques has been ...

      Evaluation of identifier based and & non-identifier based adaptive supervisory & control using a benchmark example 

      Baldi, S.; Ioannou, Petros A.; Mosca, E. (2010)
      Several classes of identifier and non-identifier based adaptive control schemes using a supervisory switching logic have been proposed in the literature. These schemes are based on different assumptions and claim to guarantee ...

      A feedback-based approach to reduce duplicate messages in unstructured peer-to-peer networks 

      Papadakis, Charis; Fragopoulou, Paraskevi; Markatos, Evangelos P.; Athanasopoulos, Elias; Dikaiakos, Marios D.; Labrinidis, Alexandros (Springer Science and Business Media, LLC, 2007)
      Resource location in unstructured P2P systems is mainly performed by having each node forward each incoming query message to all of its neighbors, a process called flooding. Although this algorithm has excellent response ...

      Hash-based overlay partitioning in unstructured peer-to-peer systems 

      Papadakis, Charis; Fragopoulou, Paraskevi; Markatos, Evangelos P.; Dikaiakos, Marios D.; Labrinidis, Alexandros (2009)
      Unstructured peer-to-peer (P2P) networks suffer from the increased volume of traffic produced by flooding. Methods such as random walks or dynamic querying managed to limit the traffic at the cost of reduced network coverage. ...

      Lightweight, self-tuning data dissemination for dense nanonetworks 

      Tsioliaridou, A.; Liaskos, Christos K.; Ioannidis, S.; Pitsillides, Andreas (2015)
      A nanonetwork comprises a high number of autonomous nodes with wireless connectivity, assembled at micro-to-nanoscale. In general, manufacturing and cost considerations imply that nanonetworking approaches should have ...

      On the evaluation of caching in Vehicular Information Systems 

      Loulloudes, Nicholas; Pallis, George C.; Dikaiakos, Marios D. (2010)
      VANETs have been envisioned as an infrastructure for deploying Vehicular Information Systems (VIS) that among others provide drivers with an up-to-date view on the prevailing traffic conditions. In this work we evaluate ...
