A Handover Scheme Based on Fuzzy Logic Approach

Handover initiation demands special attention in cellular mobile systems to provide uninterrupted services to the dedicated end users. Though many handover schemes have been proposed yet it has been a big ask to deliver the desired quality of service. In this paper, an efficient handover scheme has been proposed which makes use of fuzzy logic theory. The proposed system uses four parameters to make the handover decision. These parameters are signal strength from the home base station (SSH), signal strength from the neighboring base station (SSN), distance between the mobile user (MU) and the home base station and the available network bandwidth (BW) in the neighboring cells. Higher bandwidth helps in achieving high data rates. The simulation results reveal that the proposed system executes an efficient handoff taking care of the probability of the false handover.
