An Interest Management Mechanism Based on N-Tree

This paper proposes a method for game space partitioning with N-Tree, and a predictive interest management algorithm based on the partition. This mechanism sets the playerpsilas awareness area based on the awareness model, and sets different DR thresholds for entities on the basis of the playerspsila awareness level, and reduces bandwidth cost by employing transferring different messages with different frequencies. The simulation results show that the algorithm reduces computation resource and bandwidth usage greatly compared with other kinds of interest management mechanisms, and is more suitable for scalable requirements of P2P MMOG.
