A Locality-Aware Publish/Subscribe Scheme for High Level Architecture on Structured Peer-to-Peer Networks

High Level Architecture (HLA) is a distributed simulation architecture which is applied to many simulation environments. In most of these environments, the simulation entities (called the federate in HLA) communicate with each other by interconnected local area networks (LANs). Due to the communications among federates which are in the same LAN have shorter latency and higher bandwidth, this paper proposes a message publish/subscribe scheme of HLA based on structured peer-to-peer overlay according to the principle of locality, by increasing the size of affordable federates and the size of workload by using the same hardware environment. Moreover, the run-time infrastructure (RTI) is implemented in accordance with HLA for performance evaluation. Experimental results show that the proposed scheme improves the performance of simulations.
