Research on Fairness Problem in Distributed Virtual Environment Systems

摘要

Distributed Virtual Environment (DVE) systems have become more and more important both in academic communities and the industries. To achieve fairness in DVE Systems, three factors should be considered simultaneously. They are consistency, responsiveness and usability. Most existing fairness control methods only consider the consistency requirement and the fairness of message processing, which cannot satisfy the real fairness need of users in DVE systems. In this paper, we first present a novel fairness model that takes care of all these three factors. Based on the model, we propose a two-stage fairness control method instructed by the asynchronous time model. The method can improve the overall system fairness without compromising system functionality. Experimental results show that our method can significantly improve the fairness of DVE systems.
