Abstract: The emergence of the Fog computing paradigm that leverages in-network virtualized resources raises important challenges in terms of resource and IoT application management in a heterogeneous environment offering only limited computing resources. In this work, we propose a novel Pareto-based approach for application placement close to the data sources called Multi-objective IoT Application Placement in fOg (MAPO). MAPO models applications based on a finite state machine and uses three convicting optimization objectives, namely completion time, energy consumption, and economic cost, considering both the computation and communication aspects. In contrast to existing solutions that optimize a single objective value, MAPO enables multi-objective energy and cost-aware application placement. To evaluate the quality of the MAPO placements, we created both simulated and real-world testbeds tailored for a set of medical IoT application case studies. Compared to the state-of-the-art approaches, MAPO reduces the economic cost by up to 27%, while decreasing the energy requirements by 23-68%, and optimizes the completion time by up to 7.3 times.

Keywords: Fog computing, IoT application placement, multi-objective optimization, energy consumption

Last week, Klaus Schoeffmann co-organized the 8th Video Browser Showdown (VBS) at MMM2019 in Thessaloniki, and it was a great success. For the first time they used the V3C1 dataset (Part 1 of the Vimeo Creative Commons Collection), which consists of 7475 video files that amount for about 1000 hours of content. The six participating teams (including an ITEC team with Andreas Leibetseder) could solve all visual and textual Known-Item Search (KIS) tasks, as well as all Ad-Hoc Video Search (AVS) tasks within a short amount of time! The teams have clearly demonstrated that their sophisticated video retrieval systems are very powerful and allow fast and effective content-based search in videos. They look forward to the next VBS in January 2020 in Daejeon, Korea at MMM2020! More information here: www.VideoBrowserShowdown.org

Prof. Radu Prodan coordinated EU H2020 Horizon project – ARTICONF (smART socIal media eCOsystem in a blockchaiN Federated environment) held its first kick-off meeting at Klagenfurt from January 8th – 10th 2019. The ARTICONF team comprising of international partners from Austria, Netherlands, UK, Macedonia, Portugal, Spain, and Norway pledged support to create a novel decentralized and trusted social media ecosystem.  The international team with diverse expertise ranging from blockchain to digital sociology discussed the road map of the project over three years stipulated period and outlined innovative ways of contribution to European Union’s grand vision of Next Generation Internet (NGI) goals.
