Abstract

This paper proposes architecture for Distributed Virtual Environments (DVEs) integrating

cloud and peer nodes. We define the overall structure of the architecture and propose a

flexible strategy to distribute the load due to the management of the entities of the DVE. The

proposed approach takes into account the utilization of the nodes, the economical cost due to

their use of bandwidth, and their probability of failure. A greedy heuristics is exploited to

reduce the computational cost of the algorithm in order to maintain a fair interactivity level to

the end user of the DVE. A mobility model generating realistic Second Life traces is

exploited to evaluate our algorithm. The experimental results show the effectiveness of our

approach.
