An Adaptive Handover Prediction Scheme for Seamless Mobility based-Wireless Networks

In this paper, we propose an Adaptive Handover Prediction scheme (AHP) for seamless mobility based wireless networks. That is, the AHP scheme incorporates fuzzy logic with AP prediction process in order to lend cognitive capability to handover decision making. Selection metrics, including received s...
