The peer-to-peer networking concept has revolutionized the cost structure of Internet data dissemination by making large scale content delivery with low server cost feasible. In a peer-to-peer network, the total upload capacity increases with the number of down loaders instead of staying constant as in a client-server architecture, making it highly scalable. Despite of its importance, the problem...
We investigate the scalability of distributed virtual environments (DVEs) based on a structured peer-to-peer (P2P) overlay. We focus on network load and message routing latency. To this end, we study a prototypical DVE consisting of a simple game scenario and a P2P architecture based on Pastry and Scribe as proposed by Knutsson et al.. Both our theoretical analysis and simulation results show that...
In this paper we consider the problem of how several observer nodes can cooperatively make reliable judgements about one mobile node. These judgments shall not only cover the mere presence or absence of the mobile node, but also include coarse indications about the distance of the mobile node to the observers. To this end, we present and investigate in this paper a scheme for distance classification...
