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, we 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.In addition to it, we also propose a pro-active Load Balancing scheme which completely avoids unnecessary overloading of access points by considering the load at the target access point before associating with it.
