Real Time P2P Network Simulation for Very Large Virtual Environment

The ever increasing speed of Internet connections has led to a point where it is actually possible for every end user to seamlessly share data on Internet. Peer-to-peer (P2P) networks are typical of this evolution. The goal of our paper is to show that thanks to self-adaptive assignment techniques, server-less P2P networks can efficiently deal with very large environments such as met in the geo-visualisation area. Our method takes advantage of a hierarchical and progressive data structure that describes the environment. In order to assess the global efficiency of this P2P technique, we have implemented a dedicated real time simulator. Experimentation results are presented using a hierarchical LOD model of a very large urban environment
