A New Resources Discovery Based On Flooding

The resource discovery is very widespread in the p2p application domain, however the node joins dynamically, leaves, as well as the heterogeneous network architecture, which causes the resource discovery become very difficult.Int the peer-to-peer(p2p) network of Decentralized Unstructured Topology,the point route carries on through the network broadcast way, and correspondence between the points makes use of Flooding to realize the resource find and the localization. Although it has the very high efficiency in the content search aspect, simultaneously it produces a large amount of redundant information and restricts the network extendibility seriously. the existing improvement search strategy reduces the redundant news, but it also obviously reduced the news cover area. This is because the Flooding way had not considered that the inquiried historic record and the point interest which are helpful to reduce the news redundancy and the rogatory efficiency. But many networks such as Gnutella network topology and social network both have a small world and the power-law properties in the actual network environment, some points may have similar interest behavior, if these points are put together to form cluster which has the similar interest , while the others points inquire this kind of resource, on account of the points has the similar interest in same cluster, a majority of the request of inquires to be fulfilled , while will reduce the news storm which greatly by Flooding way , moreover the rogatory success ratio will enhance greatly. In my paper I will introduced what based on the Flooding resources discovery mechanism in detail.In the end ,we conclude our work ,and give a prospect of the future work.
