Next Generation Networks will employ hybrid network architectures using both cellular and ad hoc networking concepts. The vision of real-time multimedia services requires that mobility management be addressed in a proactive manner. If the user movements can be predicted accurately in a hybrid network environment then handoff/cluster change, resource reservation and context transfer procedures can be efficiently completed as required by node mobility. In this work we propose a sectorized ad hoc mobility prediction scheme for cluster change prediction. Simulation study of the scheme shows it to be efficient in terms of prediction accuracy and prediction related control overhead despite randomness in user movement.
