Description
Summary:802.11 WLANs are getting more and more popular. Even though an independent WLAN works in an optimal manner, many problems occur when they are deployed densely particularly with the advancement of new standards and new devices supporting dual- or non-standard features. Research community has been exploring an integrated system to monitor or control the APs and clients so that the network performance can be maximized. Enterprise WLAN (EWLAN) uses a central controller to address problems arising from a collection of APs and their associated clients due to their behavior with the lack of knowledge of other APs and clients in the proximity. This article presents EWLAN's architecture and characteristics. Then it presents a survey on several solutions in terms of interference mitigation, traffic balance, and mobility support.
