The DHT-based Chord protocol for P2P networks is one of the research hotspots recently. Considering the low efficiency problem on the resource lookup, we have developed a more efficient double-ring Chord protocol for P2P networks. We analyze theoretically the expectation of hops and present the simulation results.
In this paper, a crossover factor, f<sub>TIG</sub> is introduced to the Finite Persisting Sphere Genetic Algorithm (FPSGA). The factor provides a variable range of the loop in the process of Finite Persisting Sphere. By the existing of the variable range, the risk to have too large number of loop or too small number of loop in the FPSGA can be reduced. Too… (More)
