    • Algorithms for processing the group K nearest-neighbor query on distributed frameworks 

      Moutafis P., García-García F., Mavrommatis G., Vassilakopoulos M., Corral A., Iribarne L. (2021)
      Given two datasets of points (called Query and Training), the Group (K) Nearest-Neighbor (GKNN) query retrieves (K) points of the Training with the smallest sum of distances to every point of the Query. This spatial query ...

      We are living in the era of Big Data, and Spatial and Spatio-temporal Data are not an exception. Mobile apps, cars, GPS devices, ships, airplanes, medical devices, IoT devices, etc. are generating explosive amounts of data ...

    • A framework for joint network coding and transmission rate control in wireless networks 

      Kim, T. S.; Vural, S.; Broustis, I.; Syrivelis, D.; Krishnamurthy, S. V.; La Porta, T. F. (2010)
      Network coding has been proposed as a technique that can potentially increase the transport capacity of a wireless network via processing and mixing of data packets at intermediate routers. However, most previous studies ...
