Research on Direction Search Algorithm Based on LAN Agent in P2P Network

In view of the problem of slow search speed conduced by failure topology and limited retransmission nodes quantity in MDBS search algorithm; we proposed the LAN agent-based direction search algorithm-ABDS algorithm. We expounded the basic thought and design principle of ABDS algorithm and carried on the theoretical analysis to such as aspects of its accuracy and parameter values. The analysis results show that ABDS algorithm greatly improves the search speed while doesn't reduce the network coverage.
