Abstract: In this paper we propose to improve handoff performance by applying a mobility prediction technique, which is optimised using evolutionary algorithms such as genetic algorithm and particle swarm optimisation. Here, we describe a hybrid technique that uses the Grey model in combination with fuzzy logic and evolutionary algorithms. Handoff is the call handling mechanism invoked when a mobile node moves from one cell to another and the accuracy in predicting mobility holds a key to handoff performance. Our model uses the received signal strength from the base stations to help the mobile device during handoff. We also describe the optimisation criterion adopted in this paper and compare the self-tuning algorithm and the two evolutionary algorithms in terms of accuracy and faster convergence time. The improved accuracy of the approaches is shown by comparing results of simulations and experiments.
