A Novel Approach for Handoff Avoidance and Qos Improvement in WLAN
Maximizing network throughput while providing fairness is one of the key challenges in Wireless LANs (WLANs). Dense deployments of WLANs suffer from increased interference and, as a result, reduced capacity and wireless network conditions in general are diverse owing to both traffic and wireless channel variations. Hence effective mechanisms are required to exploit the diversity across a multiple access points and to provide a uniform load distribution in order to improve the QoS of users and to improve the overall composite capacity. In this paper, the authors propose a handoff scheme considering the current active application in use rather than a single fixed threshold value and dynamically changing the threshold value depending upon the currently active applications.
