An Efficient Unstructured P2P Network Search Algorithm Based on Multi-information

In order to improve the search efficiency of unstructured P2P network, the paper presents a routing algorithm based on multi-information integrated decision-making guidance. In the algorithm, indexing mechanism of neighbors' resource information is used to improve search probability and dynamic TTL adjustment mechanism is used to improve search efficiency. Meanwhile, indexing mechanism of routing information based on variable probability and management mechanism of index credibility are designed to improve the effectiveness of routing index. Simulation results show the algorithm can greatly enhance the efficiency of resource search.
