Signal to interference ratio based fuzzy logic controlled call handover

To accommodate huge traffic load cellular communication systems often use sectorized antennas at the base station in urban area where the co-channel interference is reduced. But as the number of call handover increases the handover algorithm need to be modified so as to respond faster and efficiently. It should also take into consideration the mobile velocity to avoid undue call termination and unnecessary handover for high and low velocity mobiles respectively. In this paper, a signal to interference ratio based fuzzy logic controlled mobile velocity dependent call handover algorithm is proposed and studied which shows quick response and suggest handover at positions which avoid call termination for high velocity mobiles and early handover for low velocity mobiles and applicable under any cell size.
