A Simplified Belonging Tree for Optimizing Information Transmission on Large-Scale Distributed Simulations

摘要

The distributed simulation is popular in both commercial and academic M&S. One of the main challenges faced by large-scale use is a speedy information transmission(IT) technology, where traditional ones such as unicast, broadcast and mul-ticast may not suitable for large scale applications because of the lack of transmission control. In this paper, we present a content based IT technology via a simplified belonging tree(BT). It uses attributes-value pairs and a set of predicates to formally denote information and consumer's interests. So it can transmit information based on its content rather than its destination address, which provides a fine-granularity transmission control. Based on insights of belonging relation-ships among consumer's interests, a simplified BT is proposed to preserve relationships and optimize IT. Experiments show that by contrast with the compared method, our method significantly reduces the time cost for maintaining BT and can always perform on a high level while the application scale grows.
