Project JXTA: A Loosely-Consistent DHT Rendezvous Walker

The open-source community Project JXTA defines an open set of standard protocols for ad hoc, pervasive, peer-to-peer (P2P) computing as a common platform for developing a wide variety of decentralized network applications. The following paper describes a loosely- consistent DHT walker approach for searching adver- tisements and routing queries in the JXTA rendezvous network. The loosely-consistent DHT walker uses an hybrid approach that combines the use of a DHT to index and locate contents, with a limited range walker to resolve inconsistency of the DHT within the dynamic rendezvous network. This proposed DHT approach does not require maintaining consistency across the rendezvous network, a stable super-peer infrastructure, and is well adapted to ad hoc P2P net- work with high peer churn rate.
