A Cluster-Based Channel Assignment Technique in IEEE 802.11 Networks
Channel assignment has become a critical configuration task in Wi-Fi networks due to the increasing number and density of devices which use the same frequency band in the radioelectric spectrum. There have been a number of research efforts that propose how to assign channels to the access points of...
