摘要: The peer-to-peer network for sharing information and data through direct exchange has emerged rapidly in recent years. searching problem is a basic issue that addresses the question “Where X”. Breadth-first search, mechanism used Gnutella networks [4], floods to maximize return results. Depth-first search Freenet [3] retrieves popular files faster than other but on average results are not maximized. Other algorithms networks, such as iterative deepening [9], local indices routing [2] NEVRLATE [1] provide different improved mechanisms. In this paper, we propose dominating-set-based algorithm of while keeping low cost both creating/maintaining connected-dominating-set (CDS) network. This approach based random walk. However, space restricted dominating nodes. Simulation been done compared with one using regular
