Performance Enhancement in MMOGs Using Entity Types

State management is a fundamental requirement of multi-user applications like distributed simulations or networked games. The quality of the experience of such applications heavily depends on synchronous communication. The movement of an entity from one logical zone into another initiates reorganization of the peer-to-peer structure and eventually ruins synchronous interactions. The frequent nature of such event in the distributed simulations has significant impact on the performance and cannot be ignored. In this paper, we present a performance enhancement mechanism considering the physical attributes of the entities. We demonstrate that clustering the entities based on their physical characteristics or behavior significantly reduces peer- to-peer structural reformation penalties. The effectiveness of such clustering mechanism is simulated and analyzed in the context MMOG.
