4. 17. 5G Backhauling with Software-defined Wireless Mesh Networks

   Author : Ricardo Santos; Andreas Kassler; Rui L. Agar; Karlstads universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; SDN; wireless backhaul; heterogeneous networks; mmWave; 5G; resiliency; Computer Science; Datavetenskap;

   Abstract : Current technological advances have caused an exponential growth of the number of mobile Internet-connected devices, along with their respective traffic demands. To cope with this increase of traffic demands, fifth generation (5G) network architectures will need to provide multi-gigabit capacity at the access base stations (BSs), through the deployment of ultra-dense small cells (SCs) operating with millimeter-wave (mmWave) frequencies, e.
