Trivial Support For Continous Queries in Formless Peer-To-Peer Networks
M. Chandrasekhar Varma, M. Balakrishna · 2012
This paper presents CoQUOS a scalable and lightweight middleware to support continuous queries in unstructured P2P networks. A key strength of the CoQUOS system is that it can be implemented on any unstructured overlay network. Moreover,CoQUOS preserves the simplicity and flexibility of the overlaynetwork.The CoQUOS middleware is a completely decentralized scheme to register a query at different regions of the P2P network. This mechanism includes two novel components, namely cluster resilient random walk and dynamic probability-basedquery registration technique The loosely-coupled and highly dynamic nature of underlying P2P network poses several additional challenges. This paper focuses on the issues that are of particular importance to the performance of the CoQUOS system, namely Churn of the P2P overlay and Load distribution among peers.
