In the unstructured P2P networks, the flooding resource search method may cause much communication overhead, and severely constrains the scalability of network. In order to overcome this disadvantage, a new search strategy named TTL-Search based on the local caching and the scope of searching requests is proposed in this paper. According to this strategy, the searching process is divided into two...
Due to the existence of hubs in P2P networks, the network becomes more and more vulnerable because of great reducing in defending against coordinated attacks. This paper propose a model based on trust value of nodes against vulnerability, which not only takes into account the node's connections, but also gives full consideration about the node's trust value, and the calculation of trust value is broken...
In this paper, we propose a multimedia information retrieval frame-work in distributed networks, which is suitable for both cooperative and non-cooperative environments and resistant to biased content summaries. The relations of peers are established and evolved according to their historical interactions, which are computed with a peer reputation model. Peers sharing the same topic tend to group themselves...
