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