A Novel Approach For Handoff Avoidance And Qos Improvement In Wlan

Abstract

Maximizing network throughput while providing fairness is one of the key challenges in wireless LANs

An Optimized Mechanism for Adaptive and Dynamic Policy Based Handover in Clustered Manet

“…Application Specific RSSI Observer calculates the RSSI requirement of all the active mobile nodes within a cluster according to the currently running applications in each mobile node [8]. If more than one application is running simultaneously in a mobile node and all applications require different RSSI values then this module selects the maximum of them as RSSI AST .…”

“…A probability based node selection method [7] identifies the inter-mediate node with optimum stored energy that could withstand through duration of connection. A handover 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 [8] have been used to avoid unnecessary handovers.…”
