Abstract
Handover in 5G wireless networks introduces new and complex challenges because a user not only changes between base stations or access technologies, but also between slices. Users should select the slices that satisfy their requirements or preferences. When making a handover decision to satisfy user requirements, the constraints on Network Slicing (NS) should be considered. In this paper, we propose a Fuzzy-based system for Handover considering four parameters: Slice Delay (SD), Slice Bandwidth (SB), Slice Stability (SS) and Slice Reliability (SR) as a new parameter. From simulation results, we conclude that the considered parameters have different effects on the Handover Decision (HD). When SD is increased, the HD parameter is increased. But when SB, SS and SR are increasing, the HD parameter is decreased.
