The handover procedure of IEEE 802.11 wireless local area networks (WLANs) introduces
significant delay, which can degrade the quality of service (QoS) especially for delay …

Due to the limited coverage range of access points (APs) and the mobility of stations (STAs),
handoff occurs frequently in IEEE 802.11 wireless local area network (WLAN). However …

Recently, new technologies improve WLANs to provide high quality of service (QoS) and
support real time applications. In this paper, we improve network efficiency in terms of …

Nowadays, IEEE 802.11 WLANs have been widely deployed in parallel with the growth of
mobile devices. However, due to design choices and requirements, the communication …

In this letter, we propose an efficient channel scanning scheme for IEEE 802.11 WLANs to
reduce the handoff delay. The proposed scheme is fundamentally different from existing …

Recently, wireless LANs have become popular and more widely used. New technologies to
improve WLAN provide high data rates and support for real-time services such as Voice over …

With the development of WLAN (Wireless Local Area Network) technologies, many hotspots
have been deployed and mobile devices can get Internet services through WLAN in many …

ABSTRACT IEEE 802.11 Wireless LANs are increasingly being used in real environments
for broad-band access. Such large scale IEEE 802.11 WLAN implies the need for client …

A proactive fast handover strategy over 802.11 WLANs to reduce high delay and service
disruption during handover has been designed and implemented. By issuing proactive scan …

We propose a mobility enhancement method in which APs periodically change their RF
channels in a predetermined order that prevents overlap of neighboring APs' channels …
