The key space of the so-called Distributed Hash Tables (DHTs) is partitioned and each partition with its keys and values is assigned to a node in the DHT. For data retrieval however, the very nature of hash tables allows only exact pattern matches. We propose Cerco, a simple solution for the problem of range queries by employing a hierarchically structured P2P approach based on the principles of Distributed Hash Tables. We show that a dynamic hierarchy of DHTs with on-demand classification of items can positively influence the response time of queries while maintaining lookup correctness.

Massively multiplayer online games (MMOGs) are becoming increasingly popular today. However, even high-budget titles like World of Warcraft that have gone through extensive beta-testing suffer from downtimes because of hard- and software problems. Our approach is to use structured P2P technology for the server infrastructure of MMOGs to improve their reliability and scalability. Such P2P networks are also able to adapt to the current state of the game and handle uneven distributions of the players in the game world. Another feature of our approach is being able to add supplementary servers at runtime. Our system allows using off-the-shelf PCs as infrastructure peers for participation in different game worlds as needed. Due to the nature of the Economy of Scale the same number of hosts will provide a better service than dedicated servers for each game world.

Although a huge number of simulation models are available today, these models do not interoperate and cannot be easily combined to form a full protocol simulation stack.
