    Based on Bayesian network theorem, the paper proposed the novel trust model of P2P network named Trust-BT. The novel new Trust-BT model is based on the P2P network nodes' history of all types of transactions, prior experience, the use of Bayesian statistical analysis methods calculate the global trust value of...

    A Lightweight Cooperative Detection Framework of DDOS/DOS Attacks Based on Counting Bloom Filter

    Detection and trace-back of Distributed Denial of Service (DDoS/DoS) attacks have become a challenge for network security. In this paper, the authors propose a lightweight cooperative detection framework (CCBFF) based on counting bloom filter to detect and trace DDoS/DoS attack online. The CCBFF contains 2 counting bloom filters CBF1 and...

    A Restricted-Scope Lookup Service in Peer-to-Peer Network

    Consistent hashing-based P2P networks, which scalability is indicated by efficiency of query and maintenance cost, take the hashing algorithm as mapping relation between the data and the identifier of every node in the network. By analyzing some main characters in structured P2P network, the authors introduce the Restricted Scope Lookup...

    Applications of Local-Range Network Theory in Designed P2P Routing Algorithm

    Peer-to-peer file sharing has a great prospect, peer-to-peer search problems have become the academic focus of one of the research questions. Already distributed P2P systems for the lack of caching mechanism unorganized navigation capacity of the lack of global routing algorithm, is a disorderly search this end, this paper proposes...

    A Traffic Network Design Scheme Based on Travel Time Reliability

    On the basis of travel time reliability, this paper puts forward the concepts of absolute reliability and relative reliability to better assess road network; simultaneously, regional traffic road network reliability formula is deducted according to series and parallel connection of link, OD pair and road network. Finally, a bi-level programming...
