IoTWORLD® DQ

Distributed Queuing (DQ) is a revolutionary technology that will change the way that wireless networks operate in the future.

Its key features are:
  • Infinite number of connected devices
  • Fair resource allocation among nodes
  • Traffic prioritization: QoS-enabled
  • No congestion under any load conditions
  • Stable maximum performance
  • Performance independent of network size
  • Performance independent of network composition (no need to know the devices associated to the network). This is a key value for the IoT.
  • Maximization of data transmissions
  • Collision-free data transmissions
  • Minimization of silence periods (no backoffs or random waiting windows).
  • Performance independent of traffic load
  • Ultra-Low energy consumption

At CTTC, we have been designing, modeling and studying this technology via advanced mathematical models (Queuing theory, Probabilistic methods, and Markov Chain analysis) and computer-based simulations for the last 10 years.

Some key fields of application (already studied):

  • Wireless Access Networks for the IoT.
  • Mobile Ad Hoc Networks (example: Smart Cities).
  • Radio Frequency Identification (RFID).
  • Access Channels of 3G/LTE (Random Access Channels)
  • Body Area Networks.

Since 2014, we are proud to announce that the first proof-of-concept of this technology is already available. This was a joint effort between CTTC, UOC (Universitat Oberta de Catalunya), and UPC (Universitat Politècnica de Catalunya).
