World Wide Streams - a new World Wide Web for in-the-moment information

  • Trappeniers L.

We are evolving to a world where multi-sensory experiences and new interaction modalities become increasingly important. A world where human augmented intelligence - based on massive amounts of available data - is expected to change our lives in drastic ways. We are moving to an IoT world where information sources are many and volatile, heterogenous and nomadic. This will set the context for a different kind of data processing systems - a new WWW, World Wide Streams (WWS). This new WWS infrastructure - designed to provide personal, in-the-moment experiences - needs to deal with massive amounts of ephemeral information generated around us. It needs to provide highly-selective, scalable, and transparent filtering to select (only) the relevant pieces, and provide timely processing before the information disappears. I will sketch the technological foundations for this WWS, grounded in the Bell Labs FutureX Network vision. I will then discuss the class of unsolved problems in the area of dynamic queries on streaming data and present future research directions.

Fair Dynamic Spectrum Management for QRD-Based Precoding with User Encoding Ordering in Downstream G.fast Transmission

In next generation DSL networks such as G.fast, employing discrete multi-tone transmission in high frequencies up to 212 MHz, the crosstalk among lines reaches very high levels. To precompensate the crosstalk in downstream transmission, QRD-based precoding has been proposed as a near-optimal dynamic spectrum management (DSM) technique. However, the performance ...

Practical Mitigation of Passive Intermodulation in Microstrip Circuits

This paper presents new experimental evidence and a novel practical approach for mitigation of passive intermodulation (PIM) in microstrip circuits fabricated on commercial printed circuit board laminates. The mechanisms of distributed PIM in microstrip circuits are reviewed and a phenomenology of PIM generation due to locally enhanced electromagnetic fields at ...

Efficient Cooperative HARQ for Multi-Source Multi-Relay Wireless Networks

In this paper, we compare the performance of three different cooperative Hybrid Automatic Repeat reQuest (HARQ) protocols for slow-fading half-duplex orthogonal multiple access multiple relay channel. Channel State Information (CSI) is available at the receiving side of each link only. Time Division Multiplexing is assumed, where each orthogonal transmission occurs ...
