Efficient channel assignment is crucial for successful deployment and operation of IEEE
802.11-based WLANs. In this article we present a survey on the state of the art channel …

There is need to develop better models and characterization methods for spectrum usage
and radio environments of cognitive radios. Currently different theoretical and simulation …

In this paper, we tackle a problem of frequency assignment in Wi-Fi networks with a novel
evolutionary-type algorithm. In this version of the problem, we consider the interferences …

To meet rapidly increasing data rate requirements in WLANs, one important technique
adopted in 802.11 ac is the channel bonding (CB) scheme that combines multiple 20MHz …

The sharing of the wireless spectrum is a major concern of network administrators. Access
points in the same network interfere with each other, degrading the aggregate performance …

This paper presents a novel multi-objective hybrid metaheuristic that combines an artificial
immune system (AIS) with genetic operators to address the multi-objective Frequency …

Due to the high density of Wi‐Fi networks, especially in the unlicensed 2.4 GHz frequency
band, channel assignment has become a critical duty for achieving a satisfactory user …

As the number of WLAN users grows, the need to perform efficient radio resource
management strategies becomes essential due to the fact that most popular technologies …

In densely deployed WLAN environment, the WLAN can experience severe inter-cell
interference which may cause a considerable performance degradation. In order to mitigate …

In this paper, we propose a cloud-assisted dynamic channel assignment system, MDU-
CACS, for groups of Wi-Fi networks in a coordinated fashion to improve the performance …
