Distributed virtual environment requires high stability and low delay to support real-time data transmission for large number of users. In wireless network-based virtual environment, traditional transmission protocol fails to meet the requirements of virtual environment due to variety of nodes distribution, complexity, and difference of bandwidth. Based on our research of rate control for distributed virtual environment, we hereby propose a bandwidth self-adaptive rate control algorithm based on layers of interest. According to effective bandwidth of proxy gateway in distributed virtual environment, this method solving the problem of time inconsistency between publishers and subscribers, constraining occupied bandwidth within the range of effective bandwidth of gateways. Our experiments prove that this algorithm can solve the problem that users’needs of interactive with each other very frequently in wireless network virtual environment. The algorithm automatically match data transmission based on bandwidth and the received datagram is smooth and much more stable. The prime performances meet our expected research objectives.
