Graph Operator Modeling over Large Graph Datasets
Tasos Bakogiannis, Ioannis Giannakopoulos, Dimitrios Tsoumakos +1
As graph representations of data emerge in multiple domains, data analysts need to be able to intelligently select among a magnitude of different data graphs based on the effects d…
Skyline Queries in O(1) time?
Spyros Sioutas, Kostas Tsichlas, Andreas Kosmatopoulos +3
The skyline of a set of points () consists of the "best" points with respect to minimization or maximization of the attribute values. A point dominates another poin…
A Decision Tree Based Approach Towards Adaptive Profiling of Distributed Applications
Ioannis Giannakopoulos, Dimitrios Tsoumakos, Nectarios Koziris
The adoption of the distributed paradigm has allowed applications to increase their scalability, robustness and fault tolerance, but it has also complicated their structure, leadin…
SART: Speeding up Query Processing in Sensor Networks with an Autonomous Range Tree Structure
Spyros Sioutas, Alexandros Panaretos, Ioannis Karydis +3
We consider the problem of constructing efficient P2P overlays for sensornets providing "Energy-Level Application and Services". The method presented in \cite{SOPXM09} presents a n…
