Abstract

We researched one search algorithm based on direction in the unstructured P2P network, analyzed the limited insufficiencies of this algorithm to the search speed, we proposed the improved direction search algorithm based on LAN agent-ABDS algorithm. We expounded the basic thought and the design principle of ABDS algorithm, carried on the theoretical analysis to the aspects of accuracy and parameter value. We took simulation experiments to the improved algorithms, carried on the quantification analysis to the improved algorithms through the experimental datum, drew up charts with the experimental datum, presented the network search process through the images, all which made the complex problems be more clearer and direct-viewing. Simulation experiments verify the improved algorithms improve the search speed of the P2P network, shorten the search response time.
