A Causality Consistency Approach in Large-scale Asynchronous Distributed Virtual Environments
Since Distributed Virtual Environments (DVEs) aim to simulate the scenarios in the real world, it is required to consistently preserve the causality of event delivery with real-time property. at each node in a DVE. However, for the DVEs, especially those running on WAN and containing large-scale simulation nodes with asynchronous simulation clocks, maintaining causality of events in real time becomes a problem. In this article, a novel causality consistency approach is proposed to compare the asynchronous time values of different nodes, and keep the cause-effect relationship among received events by analyzing the causal control information recorded in the adjacency list. The experiment results show that the approach can preserve the causality of event delivery with small control overhead and consequently meet the real-time requirement of DVEs.
