Object Management Method for Air Traffic Control Simulation Based on HLA/RTI

HLA is made for interoperability and reusability as distributed system framework under DMSO. RTI provides the necessary services for message transmission, object management as HLA 's understructure. But its performance can decrease as it becomes larger and more complex because of communication overhead. To solve this problem, RTI and TCP socket are partially used during data exchange and OMM is designed to efficiently manage objects. The efficiency of the proposed method is proved through simulation when it is applied to an air traffic control simulation based on HLA/RTI.
