Handoff decision algorithm in WiFi zone using Fuzzy Logic

Abstract

The main contributions of the research paper are designing and implementation of an algorithm for handoff decision in WiFi coverage zone based on Fuzzy Logic. We have designed and implemented the handoff algorithm in WiFi coverage zone considering Free Space Propagation Model. We have considered Received Signal Strength, Channel Capacity, Network Load and User Velocity as the parameters in the algorithm. We have also studied the variation in point of handoff under the various conditions of Network Load, User Velocity and location of the access points.
