- Abstract
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 mechanism of dynamic maintenance and search routing. This new topology had good performance with constant degree and fixed adjacent nodes, supported proximity search and solved the issues that structured super-peer topology could not support the dynamic environment well. Simulation show that compared with current supper-peer topology, HPDGN reduces the bandwidth consuming during searching, and keeps less topology construction and failure repair cost.
