Researchers from CTTC, UOC, and UPC are awarded at IEEE INFOCOM 2014

The cross-institutional team of researchers formed by Pere Tuset-Peiró, Francisco Vazquez-Gallego, Dr. Jesus Alonso-Zarate, Dr. Luis Alonso and Dr. Xavier Vilajosana, joining efforts from Centre Tecnológic de Telecommunications de Catalunya (CTTC), Universitat Oberta de Catalunya (UOC)  I Universitat Politècnica de Catalunya (UPC), has been awarded with the Best Demo Runner-Up Award at the prestigious IEEE International Conference on Computer Communications (IEEE INFOCOM) 2014 with a research demo entitled: “Demonstrating Low-Power Distributed Queuing for Active RFID Communications At 433 MHz”.

The demo consists of a wireless Machine-to-Machine (M2M) dense network communicating at 433MHz, where a novel Medium Access Control (MAC) protocol has been implemented. This demonstration shows that it is possible to go away from the widely used variations of ALOHA and CSMA protocols (used in WiFi, Zigbee, 3G, LTE technologies), and overcome their well-known congestion problems. With the use of Distributed Queuing (DQ) solutions, it is possible to achieve performance which is independent of the number of devices in a network and is close to the theoretical maximum capacity of a wireless channel. One of the reasons why these solutions are not yet in the market is the number of technological challenges that remain still open to make this technology available. The research group has been working over the last years to solve all these challenges and this demo represents a major breakthrough to show that we are not that far from seeing DQ in the market and changing the way we operate wireless networks as they become denser. This technology is deemed to become a true enabler for the advent of the Internet of Things.
