Web QoS Management Model Based on CAN

A large number of works have been made to apply P2P techniques into services discovery. However, most of them only focus on matching the functional properties. This paper proposed a web QoS Model, which is based on the content addressable network. In this model, we use the non-functional properties values to match web service, and the service matching algorithm is given out. We assign a virtual weight to reduce the query cost of some nodes since they receive more query request. Experiments with real datasets show the ectiveness of the proposed scheme by comparing with KD-Tree Model.
