Development of HLA-DDS wrapper API for network-controllable distributed simulation

Abstract

These days, distributed simulation system domain is growing increasingly in terms of data size and number of data transmission. Therefore, network control mechanism for data transmission in distributed system is required. For this, we replace transport layer of HLA-based distributed simulation system using Data Distribution Service (DDS) communication. In this paper, we pursue the network-controllable distributed simulation using DDS. We suggest HLA-DDS wrapper API which combines HLA APIs and DDS APIs and wraps them to be seen as one middleware API to users. HLA-DDS wrapper API consists of simulation service APIs from HLA and QoS-based network configuration APIs from DDS and some HLA-DDS data transformation APIs for interconnecting HLA data object and DDS data object. HLA-DDS wrapper is not only allow network-controllable distributed simulation systems but also preserve existing HLA-based distributed simulation system; because HLA-DDS wrapper API comply with HLA standard APIs.
