Abstract
With the development of simulation scalability, federates of various abilities are required to cooperate in a virtual environment. Restricted to HLA(High Level Architecture) standard, all the subscribing federates have to process the same traffic from an virtual object. As a result, existing RTI(Run-Time Infrastructure) software cannot conduct flow control on low-bandwidth federates. This paper suggests to reduce the object updating frequency and to restrict the update interval based on LoI(Layer of Interest) according to the host bandwidth. A bandwidth adaptive flow control model was built on the basis of LoI. This model depicts the way to conduct flow control with fidelity guarantee. Flow control algorithms are proposed to drop update packets according to the object LoI and packet LoI. Experiments illustrated that the flow control model can cut down the federate bandwidth requirements.
