Research on index releasing in MP2P based on super-peers

Index releasing technology is used to improve the efficiency of resource search and plays an important supporting role in MP2P. While its application must be first resolve the invalid of index, the limited scope of the issue of proliferation that both are caused by the MP2P´s dynamic topology. For upper purpose, the paper presents a method of twice resources index published: in the local area using register ownership of release mechanism; the backbone network using the release mechanism of Chord-based. According to different levels of network-level structural characteristics, combined with each other to achieve the index on a large scale as diffusion. In addition, proposed methods ensure the validity of the index information to solve the index failure the survival index by maintain the node status and the correlation identify of location.
