Virtual Net: A Decentralized Architecture for Interaction in Mobile Virtual Worlds

Abstract

With the development of mobile technology, mobile virtual worlds have attracted massive users. To improve scalability, a peer-to-peer virtual world provides the solution to accommodate more users without increasing hardware investment. In mobile settings, however, existing P2P solutions are not applicable due to the unreliability of mobile devices and the instability of mobile networks. To address the issue, a novel infrastructure model, called Virtual Net, is proposed to provide fault-tolerance in managing user content and object state. In this paper, the key problem, namely object state update, is resolved to maintain state consistency and high interaction responsiveness. This work is important in implementing a scalable mobile virtual world.

A Study on Design Requirement Development and Satisfaction for Future Virtual World Systems

“…Total Recall [125] provides optimized storage efficiency with high responsiveness and low bandwidth cost. The authors of [126] proposed a content retrieval approach based on Total Recall to provide an efficient content integrity check. These properties are requested by the content persistency requirement.…”

“…As no existing architecture can fully satisfy all new requirements, is it to possibly leverage their advantages to create a new one? For answering this question, a new architecture called Virtual Net is under development to satisfy more requirements [126]. The central idea of Virtual Net is that nobody owns a virtual world, but all users collectively create a selforganized one.…”
