摘要: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 overlay network. Central to our design of 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 algorithm for propagating query to various regions of the network and dynamic probabilitybased query registration technique for ensuring that the registrations are well distributed. Our experiments show that the proposed techniques are highly effective and their overheads are low.
