| Abstract: | This paper proposes an Improved Semi-structured Adaptive Topology Scheme(ISATS) . Based on its features of notable free-rider phenomenon,it proposes an improvement to its topologic structure. By imposing the ranked neighbor caching scheme which is used for Gnutella querying,it proposes a new adaptive topology scheme. Simulation data analysis shows this scheme makes significant reduction in the network load and the response time. It enhances the efficiency of enquiries and the success rate of enquiries. |
