An interest filtering mechanism based on loi

Abstract

In large-scale DVE (Distributed Virtual Environment), data filtering is a critical factor to consider in connection with the real-time communications between simulators geographically separated. However, several existing data filtering mechanisms such as region-based, grid-based and hybrid ones result in limitations in computational complexity, filtering accuracy, or scalability. Aiming at providing an extensible filtering approach and reducing the overhead on both host and network, we propose an interest filtering mechanism based on LoI (Layer of Interest). The mechanism performs data filtering by means of multicast region publication, distributed receiver-side matching, and LoI-Based data filtering. We have implemented the mechanism into our RTI (Run-Time Infrastructure) software, and experiments are taken to demonstrate the effectiveness of it.
