The super-peer networks adopt two-layer structure to organize super-peers and ordinary peers to improve the performance of network and the search efficiency. However,the dynamic maintenance and search routing mechanism of current network topology will lead to complexity of dynamic maintenance and excessive information caused by the query. To solve these problems,this paper proposed a novel HPDG(k) graph. With this structure,it constructed a new super-peer network HPDGN based on HPDG(k) graph,and presented a...
