Proposing a novel handoff algorithm based on fuzzy logic and pre-decision method
which can adapt to the dynamic network condition and reduce the system load
is applied to the All-IP heterogeneous network for vertical handoffs.And it is combined with the forward difference prediction for the signal strength of next time to improve the handoff accuracy.The results of simulations indicate that the proposed algorithm can make accurate handoff decision and eliminate the ping-pong effect in the process of vertical handoffs.
