Abstract :
The performance or handoff algorithm is critical to the overall system performance of cellular mobile communications. This paper presents a handoff algorithm that uses adaptive handoff values based on mobile location information and cell RF propagation statistics. Analysis is focused on the probability of hard/soft handoff and the probability of dropped calls/outage in the TDMA and CDMA systems. The simulation results shorn, that the probability of unnecessary handoff is reduced using the adaptive handoff algorithm with a minor increase in the dropped-call probability. This improvement is significant if the propagation signal varies rapidly in the cell.
