About

Wireless Networks Lab (WNL) is a ‘Megagrant’ lab established in 2017 around the project on Cloudified Wireless Networks for 5G and beyond, led by Prof. Ian F. Akyildiz. The project aims to design a novel cloud architecture for wireless networks based on software-defined networking and network function virtualization concepts and essential management tools which allow satisfying the requirements for 5G and beyond.

Our areas of interest include

  • Dynamic reconfiguration of the cloudified networks, which allow significantly reducing telecom operator CAPEX and OPEX while providing high quality of experience for the end users.
  • Traffic classification in wireless networks.
  • Resource allocation for heterogeneous traffic in multi-RRH environment
  • Cooperation and coexistence for the technologies working in licensed and unlicensed spectrum (including LTE-U, LAA, Wi-Fi coexistence)
  • Centralized algorithms for managing multihop mmWave networks, including fast link setup and beamforming algorithms, routing algorithms, and resources scheduling algorithms.
  • Ultra-reliable low latency communications
  • Massive Machine-Type Communications
  • Visible light and Terahertz Communications

  • Wireless Networks Lab Publishes a Survey on Candidate Features of Wi-Fi 7 (May 12, 2020) - The paper “Current Status and Directions of IEEE 802.11be, the Future Wi-Fi 7” by WNL members Evgeny Khorov, Ilya Levitsky, and Ian F. Akyildiz has been accepted for publication in IEEE Access. The survey gives a detailed description of the activity of IEEE 802.11be Task Group. WNL members have identified the main directions of the new technology development and documented them in the paper. It focuses on the open problems that can be solved by the researchers who want to contribute to the 802.11be.
  • WNL Design on Energy Harvesting Wireless Sensor Networks is Published in MDPI Sensors Journal (May 10, 2020) - The WNL members have developed a solution for Wi-Fi HaLow networks to divide the energy-harvesting sensors into groups and to assign them the time intervals in such a way, that the sensors can deliver their data with the required reliability and at the same time consume a minimal amount of channel time. The WNL Lab solution is designed to avoid the possibility of sensors running out of energy during the transmission and thus losing their data and enables the support of thousands of energy-harvesting sensors in a Wi-Fi HaLow network.
  • WNL Lab Presents NOMA Wi-Fi Testbed with Constellation Rotation at the IEEE INFOCOM 2020 (April 23, 2020) - The paper “Prototyping NOMA Constellation Rotation in Wi-Fi” by WNL members Evgeny Khorov, Aleksey Kureev, Ilya Levitsky, and Ian F. Akyildiz and the new version of NOMA Wi-Fi Prototype will be presented at the #1 conference in telecommunications: IEEE INFOCOM 2020. The prototype is modified to enable transmission and reception of NOMA frames, where the secondary constellations that have lower power can now be rotated by 0, 45, or 90 degrees.
  • WNL Lab Publishes the Pioneering Framework Enabling Massive URLLC Applications in 5G+ Systems (March 10, 2020) - WNL team describes a pioneering framework enabling Massive URLLC applications in 5G networks, which they have developed in 2018. Providing Ultra-Reliable Low-Latency Communications (URLLC) is one of the key challenges for 5G systems, which requires the redesign of both radio access technologies and the architectures. While 3GPP and the research community focus mainly on radio low layer functionality and architectural changes that enable URLLC, WNL Lab proposes a novel cross-layer framework that extends the already standardized 5G solutions to support a very massive number of users/flows in the system.
