Improving Responsiveness By Locality In Distributed Virtual Environments

Abstract

The recent diffusion of wide area networks distributed applications, like distributed virtual environments (DV Es), for instance massively multiplayer games, requires the definition of proper consistency models and protocols. Models like perceptive consistency take into account the interactivity of these applications by defining a set of real time constraints. This paper presents MultiLags, a protocol implementing perceptive consistency which exploits DV E locality to dynamically refine the time constraints according to the network conditions. An implementation of the protocol is presented. A set of experimental results show the effectiveness of the MultiLags approach.

“…Since the AOI of a peer may be crowded, a set of optimizations are applied to reduce the number of connections with neighbouring peers. The approach defined in [4], [5], [6] exploits a publish/subscribe computational model for the interactions among peers.…”
