Research on Multicast Reliability in Distributed Virtual Environment

Abstract

This paper proposes a novel multicast reliability algorithm in distributed virtual environment. Firstly, architecture of the distributed virtual environment system is made up of three layers, which are 1) Layer 1 is made up of distributed virtual environment server, which can transmit information from internet to clients, 2) Layer 2 is constructed by clients, which are connected to a specific server and can only solve a specific task, and 3) Layer 3 are tasks which should be solved by the distributed virtual environment system. Afterwards, the multicast problem of distributed virtual environment can be converted into a tree network with several nodes, of which the key issue is how to obtain a multicast strategy with the maximum reliability satisfying several constraints. Then, a multicast reliability algorithm for the distributed virtual environment system is present by finding key nodes and key paths in the tree network. Finally, experiments are conducted by both the performance evaluation metric “average cost” and “blocking probability” to demonstrate the effectiveness of the proposed algorithm

Interaction Design of National Dance Based on Realistic 3D Character

“…It is only an important step to realize the digitized recovery of dance, but not our ultimate goal. Only through a convenient way to display, even with some entertainment features, and in the aid of high-speed network, the masses can have the opportunity to watch and understand this recovery achievement [17]. It can promote the protection and spread of the cultural heritage effetely.…”
