Efficient Query Mechanism Based on P2P Networks
一种基于对等网络的高效查询机制

How to implement the efficient query is the key point of applications deployed on P2P networks. This paper analyses the shortage of several query algorithms, and presents the process of DDI, which means distributed searching with double indices. It discusses the popularity of documents and the linking status of the networks, and calculates the availability of the nodes in whole network, determines the route of query steps. It compares the items of time using, the quantity of query requests and update information by the emulate experiments.
