Redefining distributed knowledge and data management

February 6, 2025
Posted by Melanie Schranz

The evolution of the edge-to-cloud continuum brings transformative potential, but also significant hurdles in distributed data management. The European project ACES is addressing these challenges through a cognitive-by-design methodology, moving beyond simple data storage toward active knowledge interpretation. A core innovation in ACES is the introduction of a resource pool, which presents a significant shift from current edge definitions. By leveraging technologies like CXL and PCIe switches, the system can…

Talk “Unlocking Nature’s secrets”

October 31, 2024
Posted by Melanie Schranz

Melanie Schranz, senior researcher and project leader at LAkeside Labs, headlined a Discover-US webinar, delivering her presentation Unlocking Nature’s Secrets: Engineering Cyber-Physical Systems with Swarm Intelligence. The session is available on the YouTube channel HiPEAC TV. From biological inspiration to cyber-physical reality The presentation took the audience on a journey from observing natural phenomena—such as the foraging of ants, the coordination of bee colonies, and the flocking of birds—to the…

Swarm intelligence in the factory

July 2, 2024
Posted by Melanie Schranz

Modern semiconductor production is a operating at huge complexity, often involving over 1,500 products moving through 300 processing steps across 1,200 different machines. Traditional centralized scheduling methods frequently fail to optimize these NP-hard environments in real-time. To address this, the SwarmIn project leverages Artificial Bee Colony (ABC) algorithms to create a self-organizing, bottom-up scheduling system. Unlike standard scheduling that calculates a global plan from the top down, the SwarmIn approach…

Communication demands of drone applications

May 24, 2016
Posted by Evsen Yanmaz

Small drones become increasingly popular for civil applications, including production of movies and delivery of important goods. The wireless communications and networking of drones is an essential building block in such systems. Lakeside Labs researchers have been working in this domain for several years; now they wrote a comprehensive survey article on the characteristics and requirements of drone networks. Evsen Yanmaz, senior researcher and project manager, states: “Our survey quantifies…

Achieving consensus in networks with disturbances

March 17, 2015
Posted by Christian Bettstetter

The problem of finding a consensus in a group of people occurs in many social contexts. In a similar way, distributed algorithms for consensus play an important role in networked computing and communication systems if centralized decision making is difficult or impossible. Each entity in such a system processes only local information obtained from its neighbors and ideally performs only simple computations. Despite this simplicity, the process of consensus building…

Collaborative mapping with mobile robot teams

January 15, 2015
Posted by Christian Bettstetter

New packages for the Robot Operating System (ROS) are available for autonomous exploration of unknown environments using collaborating mobile robots equipped with cameras. The software offers wireless ad hoc communications between robots, merging of maps from different robots, and coordinated selection of exploration frontiers. A prototype with up to four robots was built that demonstrates its functionality in an indoor environment. There is a broad spectrum of applications for mobile…

Job selection in UAV-based delivery services

July 31, 2014
Posted by Christian Bettstetter

Aerial delivery services using small unmanned aerial vehicles (UAVs) have been proposed by major online retailers, logistics companies, and startups. An interdisciplinary project team at the University of Klagenfurt aims at contributing to the architectural setup and distributed control of such future systems. Small UAVs have found their way to civil applications. A broad variety of UAV models has been developed and commercialized in the past few years and is…

Pulse-coupled oscillator synchronization on FPGA radios

February 8, 2014
Posted by Christian Bettstetter

The mathematical modeling of pulse-coupled biological oscillators offers a fully decentralized and scalable approach for time synchronization. There is a broad spectrum of work on pulse-coupled oscillators in physics, biology, neuroscience, and other disciplines. The communications engineering community has been interested to transfer these results to the synchronization of nodes in wireless networks. A one-to-one transfer is infeasible due to the differences between wireless and biological communications. Several extensions and…
